Usage Guidelines

The show cable mac-domain cgd-associations command displays the following information for each cable MAC domain:

Shared port adapter (SPA) downstream channels that have been added to each MAC domain.
Upstream channels associated with each SPA downstream channel and the downstream channels of the integrated cable interface line card.

If the All column in the command output indicates Y, then this indicates that all upstream channels associated with the line card downstream channels or SPA downstream channels are configured using the upstream cable connector command. If all upstream channels are not configured, then this column will not be displayed.

The SPA downstream channels that are currently active.

A SPA downstream channel is active when the corresponding modular cable interface, which represents the SPA downstream channel, and its line protocol are up. A SPA downstream channel that is considered active is an operational primary downstream channel in the cable MAC domain.

Note

For more information on Channel Grouping Domains, refer to the Cisco DOCSIS 3.0 Downstream Solution Design and Implementation Guide, Release 2.0 .

Command History

Release	Modification
12.3(21)BC	This command was introduced for the Cisco uBR10012 router.
12.3(23)BC	This command displays the MAC Domain Downstream Service Group information for primary downstream channels from the SPA as well as the Cisco uBR10-MC5X20 line card.
12.2(33)SCA	This command was integrated into Cisco IOS Release 12.2(33)SCA.
12.2(33)SCD	This command was modified. Support was added for Cisco uBR7225VXR and Cisco uBR7246VXR routers.
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR Series Converged Broadband Router.

Usage Guidelines

Use the show cable mac-domain downstream-service-group command to display MAC Domain Downstream Service Group (MD-DS-SG) information for the specified primary downstream channel.

For each fiber node, a traditional DOCSIS downstream channel on a Cisco uBR10-MC5X20 cable interface line card is used to carry MAC management and signaling messages, and the associated traditional DOCSIS upstream channel is used for return data traffic and signaling. The traditional DOCSIS downstream channel used in this way for a MAC domain is called the primary downstream channel .

Note

Beginning in Cisco IOS Release 12.3(23)BC, either an RF channel from the SPA or a Cisco uBR10-MC5X20 downstream channel can serve as a primary channel in a fiber node. Changes in Cisco IOS Release 12.3(23)BC apply to Cisco IOS Release 12.2(33)SCB but do not apply to Cisco IOS Release 12.2(33)SCA.

Usage Guidelines

This command displays information for all cable modems, for all cable modems attached to a specific CMTS cable interface, or for a particular cable modem, identified by its IP address, MAC address, or its domain name. The output is sorted by the cable interface and the cable modem’s MAC address.

Note

The upstream channel list displayed by show cable modem ip-address/mac-address [verbose]command is the subset of upstream service flow forwarding interface channel set of the cable modem.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

Tip

Several options in the show cable modem command do not pause the screen to display the information page by page, even if the terminal length command has been used to set the page size of your terminal. Paging and pausing the display could result in outdated or stale information for cable modems, and thus produce an incorrect snapshot of the current cable modem state of the system. To capture or review this information, use your terminal program’s capture buffer to save the information to a file, and then review it offline.

Tip

You can also specify the MAC address or IP address for a CPE device, and the Cisco CMTS will display the information for the cable modem that is associated with that CPE device in its internal database.

Note

If the CPE IP address is no longer associated with a cable modem, the show cable modem command might not display information about the cable modem. To display the IP address of the CPE device for the cable modem, use the clear cable host ip-address command to clear the IP address of the modem from the router database, and then enter the ping docsis mac-address command, which resolves the MAC address by sending the DOCSIS ping to the CM.

Note

When an IPv4 CPE is moved from one bundle interface to another bundle interface, the show cable modem command displays duplicate CPE device under the original modem and new modem. CPE ping may also fail. To prevent duplication, use the clear cable host command to manually remove the old CPE device entry before moving the IPv4 CPE from one bundle interface to another. Reload the CPE after moving it to another bundle interface.

Refer to the following document on Cisco.com for additional information about cable interface bundling and virtual interface bundling on the Cisco CMTS:

Cable Interface Bundling and Virtual Interface Bundling on the Cisco CMTS

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Operation of the show cable modem Commands with Different Cable Interface Line Cards

The show cable modem commands display the most current information for standard cable interface line cards. If the card itself is down, the show cable modem commands still show whatever information is appropriate (such as offline cable modems and flap list information).

The show cable modem commands function slightly different when used on routers that are using Broadband Processing Engine (BPE) cable interface line cards (such as the Cisco uBR-MC16U/X, Cisco uBR-MC28U/X, or Cisco uBR10-MC5X20S/U/H). When BPE cards are the only cable interface cards installed, the show cable modem commands do not display any output until at least one BPE card is up and communicating with the router processor. If the BPE cards are not yet up, the show cable modem command does not display any output.

Note

The hccp commands are not supported on the Cisco cBR router for Cisco IOS-XE 3.15.0S.

Examples

The following sample output from the show cable modem command shows the default cable modem displays for individual cable modems.

Note

When a DCC occurs, the cable modem US and DS counters are reset. The US and DS counters include counters such as data and throughput seen in the show cable modem (mac-address) verbose command output and packets and bytes seen in the show cable modem (mac-address) counters command output.

Note

The “Number of CPES” field shows the value set for the CM, not the value for the CMTS that is set by the cable modem max-cpe command. In Cisco IOS Release 12.2(15)BC1 and later releases, the verbose display also includes information about the dynamic shared-secret feature (see the cable dynamic-secret command).

Note

An asterisk (*) in the Receive Power column indicates that a power adjustment has been made for that CM. An exclamation point (!) in the Receive Power column indicates that the cable modem has reached its maximum power transmit level and cannot increase its power level further. An exclamation point (!) in the Timing Offset column indicates that the cable modem has exceeded the maximum delay and timing offset specified by the cable map-advance command. A pound sign (#) in the MAC State column indicates that the cable tftp-enforce mark-only command has been used for the cable modem to attempt a TFTP download of the DOCSIS configuration file before registering, but the cable modem did not do so (Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases).

Tip

The show cable modem command displays the cable modem timing offset in DOCSIS ticks, while other commands, such as cable map-advance, display the offset in microseconds. Use the following method to convert microseconds to DOCSIS ticks: ticks = microseconds*64/6.25 .

Examples

Effective from Cisco IOS Release 12.2(33)SCG5, the verbose keyword displays the status of the Upstream Drop Classifier (UDC) feature for a specific cable modem. The “UDC Enabled” field displays ‘Y’ if it is enabled.

The following example shows the output of the show cable modem command with the verbose keyword for the UDC feature:

Note

When the verbose keyword is used without a specific MAC address, the UDC Enabled status of each cable modem on the interface is displayed.

Examples

The following is a sample output for the verbose option that displays the channel IDs for 16 downstream channels and channel information for 4 upstream channels of a cable modem:

Upstream signal-to-noise ratio (SNR) for a particular cable modem (CM), in decibels (dB).

Upstream SM MER (dB)

Upstream station maintenance (SM) modulation error ratio (MER) for a particular cable modem, in decibels (dB).

Upstream Data MER (dB)

Upstream modulation error ratio (MER) for a particular cable modem, in decibels (dB). This field is displayed only when RF adaptation is enabled.

RxPwr, Received Power

Average power in dBmV for the upstream channel symbol rate for the CM. With default settings, 0 dBmV is considered optimal, but a range of -1 to 1 dBmV is allowable. When cable modems exceed this range, older Cisco IOS releases supported a drop to as low as -2 dBmV. Recent Cisco IOS releases support a drop to as low as -4 dBmV.

This field supports a resolution of 0.25 dBmV, but the dB resolution level for cable modems and for the Cisco CMTS are slightly higher—approximately 1.0 and 1.4 dB.

Note

An asterisk (*) in the RxPwr column indicates that a power adjustment has been made for that CM. An exclamation point (!) indicates that the cable modem has reached its maximum power transmit level and cannot increase its power level further.

Timing Offset and Initial Timing Offset

Timing offset for the CM, in ticks, as recognized on the CMTS. (A tick, as used here, is 6.25/64 microseconds.) This is the delay between when a particular cable modem is scheduled to make a transmission and when the CMTS actually receives it.

Note

An exclamation point (!) in the Timing Offset column indicates that the cable modem has exceeded the maximum delay and timing offset specified by the cable map-advance command.

Note

The timing offset shown here is typically smaller than the TX Time Offset value shown by the show cable modem remote-query command, because the latter value is the offset as recognized on the cable modem (which will include any internal delay between when the cable modem software begins the transmission and when the bits actually appear on the local cable interface).

Reported Transmit Power (dBmV)

Reported Transmit Power level by the cable modem for each upstream channel. This applies only to the cable modems operating in the MTC mode.

Peak Transmit Power (dBmV)

This is the maximum transmit power level that the cable modem in the MTC mode could transmit at for the upstream channel.

Minimum Transmit Power (dBmV)

This is the minimum transmit power level that the cable modem in the MTC mode could transmit at for the upstream channel.

The table below shows the possible values for the MAC state field.

Note

The CM MAC state field can also be retrieved using SNMP by getting the value of the cdxCmtscable modemstatusValue object in the CISCO-DOCS-EXT-MIB. The following symbols appended to the modem state indicate a special condition:An exclamation mark (!) indicates that the cable dynamic-secret command is used with either the mark or reject keyword and the cable modem has failed the dynamic secret authentication check.An ampersand (and) indicates that the cable modem has registered using a self-signed certificate. This is inherently not secure and can be avoided by negating the cable privacy accept-self-signed-certificate command.The asterisk () indicates that the cable modem does not satisfy the BPI+ policy and the data traffic is blocked. The cable privacy bpi-plus-policy command enforces this requirement.A hash sign () indicates that the cable modem is using an unknown configuration file. To solve this problem, use the cable dynamic-secret command with the reject keyword. This will reject registration for cable modems with DOCSIS configuration files. In Cisco IOS Releases 12.1(20)EC, 12.2(15)BC1, and earlier releases, when network access is disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) even if BPI encryption fails.

MAC State Value

Description

Ranging Status Conditions for Devices Using IPv4 Addressing

init(r1)

The cable modem sent initial ranging.

init(r2)

The cable modem is ranging. The CMTS received initial ranging from the cable modem and has sent RF power, timing offset, and frequency adjustments to the CM.

init(rc)

Ranging has completed.

Note

If a cable modem appears to be stuck in this state, it could be that the cable modem is able to communicate successfully on the cable network, but that the upstream is at capacity and does not have any additional bandwidth to allow the cable modem to finish registration and come online. Either manually move one or more cable modems to other upstreams, or enable load balancing on the upstream using the cable load-balance group commands.

Registration and Provisioning Status Conditions for Devices Using IPv4 Addressing

If early authentication and encryption is used, the letter ‘s’ is appended to these states to indicate secure registration.

init(d)

The DHCP request was received, as DHCPDISCOVER. This also indicates that the first IP broadcast packet has been received from the CM.

init(dr)

The DHCP request has been sent to the cable modem.

init(i)

The cable modem has received the DHCPOFFER reply (DHCPACK) from the DHCP server that has assigned an IP address to the modem, but the modem has not yet replied with a DHCPREQUEST message requesting that particular IP address, nor has it sent an IP packet with that IP address.

Note

If a cable modem appears to be stuck in this state, the cable modem has likely received the DHCPOFFER reply from the DHCP server, but this reply might have contained one or more invalid options for that particular CM.

init(io)

The Cisco CMTS has seen the DHCP offer as sent to the cable modem from the DHCP server that has assigned an IP address to the modem.

init(o)

The cable modem has begun to download the option file (DOCSIS configuration file) using the Trivial File Transfer Protocol (TFTP), as specified in the DHCP response. If the cable modem remains in this state, it indicates that the download has failed.

init(t)

Time-of-day (TOD) exchange has started.

Registration and Provisioning Status Conditions for Devices Using IPv6 Addressing

If early authentication and encryption is used, the letter ‘s’ is appended to these states to indicate secure registration.

init6(t)

The Cisco CMTS router has seen the REQUEST message from the cable modem to the TOD server.

Non-error Status Conditions

cc(r1)

The cable modem had registered and was online, but has received a Downstream Channel Change (DCC) or Upstream Channel Change (UCC) request message from the CMTS. The cable modem has begun moving to the new channel, and the CMTS has received the CM’s initial ranging on the new downstream or upstream channel. At the MAC layer, the cable modem is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

cc(r2)

This state should normally follow cc(r1) and indicates that the cable modem has finished its initial ranging on the new channel, and is currently performing continuous ranging on the new channel. At the MAC layer, the cable modem is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

offline

The cable modem is considered offline (disconnected or powered down).

resetting

The cable modem is being reset and will shortly restart the ranging and registration process.

online

The cable modem has registered and is enabled to pass data on the network.

online(d)

The cable modem does not forward traffic to or from the CPE devices, but the CMTS can continue to communicate with the cable modem using DOCSIS messages and IP traffic (such as SNMP commands).

Note

If BPI was enabled in the DOCSIS configuration file sent to the CM, assume that the cable modem is using BPI encryption, unless other messages show that the BPI negotiation and key assignments have failed.

online(pkd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and KEK is assigned.

Note

This state is equivalent to the online(d) and online(pk) states.

online(ptd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

online(pk)

The cable modem registered, BPI is enabled and KEK is assigned.

online(pt)

The cable modem registered, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

If network access was disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) instead of online(pt) even when BPI encryption is enabled and operational.

expire(pk)

The cable modem registered, BPI is enabled, KEK was assigned, but the current KEK expired before the cable modem could successfully renew a new KEK value.

expire(pkd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, KEK was assigned, but the current KEK expired before the cable modem could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pk) states.

expire(pt)

The cable modem registered, BPI is enabled, TEK was assigned, but the current TEK expired before the cable modem could successfully renew a new KEK value.

expire(ptd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, TEK was assigned, but the current TEK expired before the cable modem could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pt) states.

Error Status Conditions

reject(m)

The cable modem attempted to register but registration was refused due to a bad Message Integrity Check (MIC) value. This also could indicate that the shared secret in the DOCSIS configuration file does not match the value configured on the CMTS with the cable shared-secret command.

In Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases, this could also indicate that the cable tftp-enforce command has been used to require that a cable modem attempt a TFTP download of the DOCSIS configuration file before registering, but the cable modem did not do so.

reject(c)

The cable modem attempted to register, but registration was refused due to a a number of possible errors:

The cable modem attempted to register with a minimum guaranteed upstream bandwidth that would exceed the limits imposed by the cable upstream admission-control command.
The cable modem has been disabled because of a security violation.
A bad class of service (COS) value in the DOCSIS configuration file.
The cable modem attempted to create a new COS configuration but the CMTS is configured to not permit such changes.
The cable modem failed the timestamp check for its DOCSIS configuration file. (This could indicate a possible theft-of-service attempt, or a problem with the synchronization of the clocks on the cable modem and CMTS.)

reject(pk)

KEK key assignment is rejected, and the modem has not been authenticated.

reject(pkd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because KEK key assignment was rejected.

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because TEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pt) states.

reject(ts)

The cable modem attempted to register, but registration failed because the TFTP server timestamp in the cable modem registration request did not match the timestamp maintained by the CMTS. This might indicate that the cable modem attempted to register by replaying an old DOCSIS configuration file used during a prior registration attempt.

reject(ip)

The cable modem attempted to register, but registration failed because the IP address in the cable modem request did not match the IP address that the TFTP server recorded when it sent the DOCSIS configuration file to the CM. IP spoofing could be occurring.

reject(na)

The cable modem attempted to register, but registration failed because the cable modem did not send a Registration-Acknowledgement (REG-ACK) message in reply to the Registration-Response (REG-RSP) message sent by the CMTS. A Registration-NonAcknowledgement (REG-NACK) is assumed.

IOS-XE 3.15.0S	This command was implemented on the Cisco cBR Series Converged Broadband Router. The name is removed.

Usage Guidelines

The show cable modem cnr command displays information on the current CNR value for cable modems that are using interfaces on the following cable line cards:

Cisco uBR-MC16U/X
Cisco uBR-MC28U/X
Cisco uBR10-MC5X20S/U/H
Cisco uBR-E-28U
Cisco uBR-E-16U
Cisco cBR-8 CCAP line cards

For cable modems on all other interfaces, this command displays information about the current SNR value of the modem.

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the Cisco CMTS router before any domain name can be used as part of a cable command.

Starting Cisco IOS Release 12.2(33)SCF, carrier-to-noise plus interference ratio (CNiR [CNR]) can be measured for all upstream channels irrespective of whether spectrum management is enabled or not for the upstream channels. Therefore, the output of the show cable modem cnr command displays only the CNR (CNiR) values for all the upstream channels for a specific cable modem.

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address cnr command might not show a particular cable modem until the Cisco CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address cnr command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when the HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond with a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.1(12)EC, Cisco IOS Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Examples

This example shows the output of the show cable modem cnr command for a CM:

Router# show cable modem 10.20.114.34 cnr
 
MAC Address    IP Address      I/F         MAC         Prim  snr/cnr

Table below describes the significant fields shown in the display:

Table 11 show cable modem cnr Field Descriptions

Field

Description

MAC Address

MAC address of the CM.

IP Address

IP address that the DHCP server has assigned to the CM.

I/F

Cable interface line card providing the upstream for this CM.

MAC State

Current state of the MAC layer.

Prim Sid

Primary Sid assigned to this CM.

In Cisco IOS Release 12.2(33)SCC, this field is renamed to SID and represents multiple upstream connections with unique SIDs providing service to a single CM.

ExPwr (dBmv)

Expected carrier power level, in decibel millivolts (dBmv).

RxPwr (dBmv)

Received carrier power level, in decibel millivolts (dBmv).

snr/cnr (db)

The current upstream CNR or SNR for this particular CM, in decibels (dB). In Cisco IOS Release 12.2(15)BC1 and later releases, this field shows “-----” for offline cable modems.

Note

You can also use the show controllers cable command to display the SNR or CNR for a cable interface line card, but this value is only an estimate because it uses a random sampling of modems to determine the average for the card at any particular time. The CNR value shown by the show controllers cable command can therefore appear to fluctuate compared to the individual values shown by the show cable modem cnr command.

Table below shows the possible values for the MAC state field.

Table 12 MAC State Field Descriptions

MAC State Value¹

Description

Registration and Provisioning Status Conditions for Devices Using IPv4 Addressing

init(r1)

CM sent initial ranging.

init(r2)

CM is ranging. The Cisco CMTS received initial ranging from the CM and has sent RF power, timing offset, and frequency adjustments to the CM.

init(rc)

Ranging has completed.

Note

If a CM appears to be stuck in this state, it could be that the CM is able to communicate successfully on the cable network, but that the upstream is at capacity and does not have any additional bandwidth to allow the CM to finish registration and come online. Either manually move one or more CMs to other upstreams, or enable load balancing on the upstream using the cable load-balance group commands.

init(d)

DHCP request was received, as DHCPDISCOVER. This also indicates that the first IP broadcast packet has been received from the CM.

init(dr)

Cable modem has broadcast a DHCP REQUEST packet back to the DHCP server.

init(i)

Cable modem has received the DHCPOFFER reply (DHCPACK) from the DHCP server that has assigned an IP address to the modem, but the modem has not yet replied with a DHCPREQUEST message requesting that particular IP address, nor has it sent an IP packet with that IP address.

Note

If a CM appears to be stuck in this state, the CM has likely received the DHCPOFFER reply from the DHCP server, but this reply might have contained one or more invalid options for that particular CM.

init(io)

Cisco CMTS learns the DHCP offer that is sent to the cable modem from the DHCP server, which has assigned an IP address to the modem.

init(o)

CM has begun to download the option file (DOCSIS configuration file) using the Trivial File Transfer Protocol (TFTP), as specified in the DHCP response. If the CM remains in this state, it indicates that the download has failed.

init(t)

Time-of-day (ToD) exchange has started.

resetting

CM is being reset and will shortly restart the registration process.

Registration and Provisioning Status Conditions for Devices Using IPv6 Addressing

init6(s)

Cisco CMTS router learns the DHCPv6 SOLICIT message from the CM.

init6(a)

Cisco CMTS router learns the ADVERTISE message from the DHCPv6 server to the CM.

init6(r)

Cisco CMTS router learns the REQUEST response from the CM to the DHCPv6 server.

init6(i)

Cisco CMTS router learns the REPLY message from the DHCPv6 server to the CM.

init6(o)

Cisco CMTS router learns the REQUEST message from the CM to the TFTP server.

init6(t)

Cisco CMTS router learns the REQUEST message from the CM to the ToD server.

Non-error Status Conditions

cc(r1)

CM had registered and was online, but has received a Downstream Channel Change (DCC) or Upstream Channel Change (UCC) request message from the Cisco CMTS. The CM has begun moving to the new channel, and the Cisco CMTS has received the initial ranging of the CM on the new downstream or upstream channel. At the MAC layer, the CM is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

cc(r2)

This state should normally follow cc(r1) and indicates that the CM has finished its initial ranging on the new channel, and is currently performing continuous ranging on the new channel. At the MAC layer, the CM is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

offline

CM is considered offline (disconnected or powered down).

online

CM has registered and is enabled to pass data on the network.

online(d)

CM is registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. The CM does not forward traffic to or from the CPE devices, but the Cisco CMTS can continue to communicate with the CM using DOCSIS messages and IP traffic (such as SNMP commands).

Note

If BPI was enabled in the DOCSIS configuration file sent to the CM, assume that the CM is using BPI encryption unless other messages show that the BPI negotiation and key assignments have failed.

online(pkd)

CM is registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and KEK is assigned.

Note

This state is equivalent to the online(d) and online(pk) states.

online(ptd)

CM is registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

This state is equivalent to the online(d) and online(pt) states.

online(pk)

CM is registered, BPI is enabled and KEK is assigned.

online(pt)

CM is registered, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

If network access was disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) instead of online(pt) even when BPI encryption is enabled and operational.

Note

If an exclamation point (!) appears in front of one of the online states, it indicates that the cable dynamic-secret command has been used with either the mark or reject option, and that the cable modem has failed the dynamic secret authentication check.

expire(pk)

CM is registered, BPI is enabled, KEK was assigned, but the current KEK expired before the CM could successfully renew a new KEK value.

expire(pkd)

CM is registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, KEK was assigned, but the current KEK expired before the CM could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pk) states.

expire(pt)

CM is registered, BPI is enabled, TEK was assigned, but the current TEK expired before the CM could successfully renew a new KEK value.

expire(ptd)

CM is registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, TEK was assigned, but the current TEK expired before the CM could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pt) states.

Error Status Conditions

reject(m)

CM attempted to register but registration was refused due to a bad Message Integrity Check (MIC) value. This also could indicate that the shared secret in the DOCSIS configuration file does not match the value configured on the Cisco CMTS with the cable shared-secret command.

In Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases, this could also indicate that the cable tftp-enforce command has been used to require that a CM attempt a TFTP download of the DOCSIS configuration file before registering, but the CM did not do so.

reject(c)

CM attempted to register, but registration was refused due to a a number of possible errors:

CM attempted to register with a minimum guaranteed upstream bandwidth that would exceed the limits imposed by the cable upstream admission-control command.
CM has been disabled because of a security violation.
Bad class of service (CoS) value in the DOCSIS configuration file.
CM attempted to create a new CoS configuration but the Cisco CMTS is configured to not permit such changes.
CM failed the timestamp check for its DOCSIS configuration file. (This could indicate a possible theft-of-service attempt, or a problem with the synchronization of the clocks on the CM and Cisco CMTS.)

reject(pk)

KEK key assignment is rejected, BPI encryption has not been established.

reject(pkd)

CM is registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because KEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pk) states.

reject(pt)

TEK key assignment is rejected, BPI encryption has not been established.

reject(ptd)

CM is registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because TEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pt) states.

Note

In Cisco IOS Release 12.1(20)EC, Cisco IOS Release 12.2(15)BC1, and earlier releases, when network access is disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) even if BPI encryption fails. Use the show cable modem mac-address command to confirm whether BPI is enabled or disabled for a particular cable modem.

reject(ts)

CM attempted to register, but registration failed because the TFTP server timestamp in the CM registration request did not match the timestamp maintained by the CMTS. This might indicate that the CM attempted to register by replaying an old DOCSIS configuration file used during a prior registration attempt.

reject(ip)

CM attempted to register, but registration failed because the IP address in the CM request did not match the IP address that the TFTP server recorded when it sent the DOCSIS configuration file to the CM. IP spoofing could be occurring.

reject(na)

CM attempted to register, but registration failed because the CM did not send a Registration-Acknowledgement (REG-ACK) message in reply to the Registration-Response (REG-RSP) message sent by the Cisco CMTS. A Registration-NonAcknowledgement (REG-NACK) is assumed.

¹ The CM MAC state field can also be retrieved using SNMP by getting the value of the cdxCmtsCmStatusValue object in the CISCO-DOCS-EXT-MIB.

IOS-XE 3.15.0S	This command was implemented on the Cisco cBR Series Converged Broadband Router. The upstream and name keywords and logical-channel-index variable were removed.

Usage Guidelines

This command displays connectivity information for all cable modems , for all cable modems attached to a specific CMTS cable interface, or for a particular CM, as identified by its IP address or MAC address.

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

Note

The show cable modem connectivity command replaces the connectivity option for the show interface cable sid command, because the connectivity statistics are better managed on a per-modem basis than on a per-SID basis.

Usage Guidelines

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

IOS-XE 3.15.0S	This command was implemented on the Cisco cBR Series Converged Broadband Router. The upstream and name keywords and logical-channel-index variable were removed.

Usage Guidelines

This command displays packet header error information for all cable modems , for all cable modems attached to a specific CMTS cable interface, or for a particular CM, as identified by its IP address or MAC address.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.2(15)BC1 and later releases, use the clear cable modem flap-counters command to clear these counters.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Examples

The following example shows sample output for the show cable modem errors command for all cable modems on a particular cable interface.

If this occurs, wait a minute or so and retry the command.

Note

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

For cable modems in MTC mode, the show cable modem flap command will display aggregate data across all upstream channels for each flap detector. However, for a single MTC cable modem, the show cable modem flap command will display per channel flap information.

Note

The output of the show cable modem flap command will remain unchanged for non-MTC mode cable modems.

Usage Guidelines

Use the show cable modem ipv6 command without any options to display IPv6 information for all CMs on the CMTS router.

Using the keyword options, you can display IPv6 information by IP address (IPv4 or IPv6) of a particular CM, for all CMs associated with a specified cable interface, by MAC address of a CM, or by domain name of a CM.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the Cisco CMTS router before any domain name can be used as part of a cable command.

To display the number of CPEs behind a CM, use the show cable modem ipv6 registered command.

To display CPE information behind a specific CM, use the show cable modem mac-address ipv6 cpe command.

IP address acquired by the CM. Prior to acquisition of the IP address, or if the CM fails registration, the following output is shown:

IPv4 address not yet acquired—”0.0.0.0”
IPv6 address not yet acquired—“::”
CM fails IPv6 registration, but online with IPv4 address or CM fails IPv4 registration, but online with IPv6 address: “---”
IPv6 address of IPv4-only CM, or IPv4 address of an IPv6-only CM: “---”

Domain Name

Domain name for the CM.

Table below shows the possible values for the MAC state field:

Table 27 Descriptions for the MAC State Field

MAC State Value

²

Description

Registration and Provisioning Status Conditions for Devices Using IPv4 Addressing

init(r1)

The CM sent initial ranging.

init(r2)

The CM is ranging. The CMTS received initial ranging from the CM and has sent RF power, timing offset, and frequency adjustments to the CM.

init(rc)

Ranging has completed.

Note

If a CM appears to be stuck in this state, it could be that the CM is able to communicate successfully on the cable network, but that the upstream is at capacity and does not have any additional bandwidth to allow the CM to finish registration and come online. Either manually move one or more CMs to other upstreams, or enable load balancing on the upstream using the cable load-balance group commands.

init(d)

The DHCP request was received, as DHCPDISCOVER. This also indicates that the first IP broadcast packet has been received from the CM.

init(dr)

The DHCP request has been sent to the cable modem.

init(i)

The cable modem has received the DHCPOFFER reply (DHCPACK) from the DHCP server that has assigned an IP address to the modem, but the modem has not yet replied with a DHCPREQUEST message requesting that particular IP address, nor has it sent an IP packet with that IP address.

Note

If a CM appears to be stuck in this state, the CM has likely received the DHCPOFFER reply from the DHCP server, but this reply might have contained one or more invalid options for that particular CM.

init(io)

The Cisco CMTS has seen the DHCP offer as sent to the cable modem from the DHCP server that has assigned an IP address to the modem.

init(o)

The CM has begun to download the option file (DOCSIS configuration file) using the Trivial File Transfer Protocol (TFTP), as specified in the DHCP response. If the CM remains in this state, it indicates that the download has failed.

init(t)

Time-of-day (TOD) exchange has started.

resetting

The CM is being reset and will shortly restart the registration process.

Registration and Provisioning Status Conditions for Devices Using IPv6 Addressing

init6(s)

The Cisco CMTS router has seen the DHCPv6 SOLICIT message from the CM.

init6(a)

The Cisco CMTS router has seen the ADVERTISE message from the DHCPv6 server to the CM.

init6(r)

The Cisco CMTS router has seen the REQUEST response from the CM to the DHCPv6 server.

init6(i)

The Cisco CMTS router has seen the REPLY message from the DHCPv6 server to the CM.

init6(o)

The Cisco CMTS router has seen the REQEST message from the CM to the TFTP server.

init6(t)

The Cisco CMTS router has seen the REQUEST message from the CM to the TOD server.

Non-error Status Conditions

cc(r1)

The CM had registered and was online, but has received a Downstream Channel Change (DCC) or Upstream Channel Change (UCC) request message from the CMTS. The CM has begun moving to the new channel, and the CMTS has received the CM’s initial ranging on the new downstream or upstream channel. At the MAC layer, the CM is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

cc(r2)

This state should normally follow cc(r1) and indicates that the CM has finished its initial ranging on the new channel, and is currently performing continuous ranging on the new channel. At the MAC layer, the CM is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

offline

The CM is considered offline (disconnected or powered down).

online

The CM has registered and is enabled to pass data on the network.

online(d)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. The CM does not forward traffic to or from the CPE devices, but the CMTS can continue to communicate with the CM using DOCSIS messages and IP traffic (such as SNMP commands).

Note

If BPI was enabled in the DOCSIS configuration file sent to the CM, assume that the CM is using BPI encryption, unless other messages show that the BPI negotiation and key assignments have failed.

online(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and KEK is assigned.

Note

This state is equivalent to the online(d) and online(pk) states.

online(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

This state is equivalent to the online(d) and online(pt) states.

online(pk)

The CM registered, BPI is enabled and KEK is assigned.

online(pt)

The CM registered, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

If network access was disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) instead of online(pt) even when BPI encryption is enabled and operational.

Note

If an exclamation point (!) appears in front of one of the online states, it indicates that the cable dynamic-secret command has been used with either the mark or reject option, and that the cable modem has failed the dynamic secret authentication check.

expire(pk)

The CM registered, BPI is enabled, KEK was assigned, but the current KEK expired before the CM could successfully renew a new KEK value.

expire(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, KEK was assigned, but the current KEK expired before the CM could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pk) states.

expire(pt)

The CM registered, BPI is enabled, TEK was assigned, but the current TEK expired before the CM could successfully renew a new KEK value.

expire(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, TEK was assigned, but the current TEK expired before the CM could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pt) states.

Error Status Conditions

reject(m)

The CM attempted to register but registration was refused due to a bad Message Integrity Check (MIC) value. This also could indicate that the shared secret in the DOCSIS configuration file does not match the value configured on the CMTS with the cable shared-secret command.

In Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases, this could also indicate that the cable tftp-enforce command has been used to require that a CM attempt a TFTP download of the DOCSIS configuration file before registering, but the CM did not do so.

reject(c)

The CM attempted to register, but registration was refused due to a a number of possible errors:

The CM attempted to register with a minimum guaranteed upstream bandwidth that would exceed the limits imposed by the cable upstream admission-control command.
The CM has been disabled because of a security violation.
A bad class of service (COS) value in the DOCSIS configuration file.
The CM attempted to create a new COS configuration but the CMTS is configured to not permit such changes.
The CM failed the timestamp check for its DOCSIS configuration file. (This could indicate a possible theft-of-service attempt, or a problem with the synchronization of the clocks on the CM and CMTS.)

reject(pk)

KEK key assignment is rejected, BPI encryption has not been established.

reject(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because KEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pk) states.

reject(pt)

TEK key assignment is rejected, BPI encryption has not been established.

reject(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because TEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pt) states.

Note

In Cisco IOS Release 12.1(20)EC, Cisco IOS Release 12.2(15)BC1, and earlier releases, when network access is disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) even if BPI encryption fails. Use the show cable modemmac-address command to confirm whether BPI is enabled or disabled for a particular cable modem.

reject(ts)

The CM attempted to register, but registration failed because the TFTP server timestamp in the CM registration request did not match the timestamp maintained by the CMTS. This might indicate that the CM attempted to register by replaying an old DOCSIS configuration file used during a prior registration attempt.

reject(ip)

The CM attempted to register, but registration failed because the IP address in the CM request did not match the IP address that the TFTP server recorded when it sent the DOCSIS configuration file to the CM. IP spoofing could be occurring.

reject(na)

The CM attempted to register, but registration failed because the CM did not send a Registration-Acknowledgement (REG-ACK) message in reply to the Registration-Response (REG-RSP) message sent by the CMTS. A Registration-NonAcknowledgement (REG-NACK) is assumed.

² The CM MAC state field can also be retrieved using SNMP by getting the value of the cdxCmtsCmStatusValue object in the CISCO-DOCS-EXT-MIB.

Usage Guidelines

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Cisco IOS Release 12.3(17a)BC introduces changes for two versions of the show cable modem mac command.

show cable modem mac summary

The information displayed with this command is revised. The DOCSIS 2.0 column in the Quality of Service (QoS) Provision Mode field has been removed, as this field is not applicable to QoS provisioning in DOCSIS 2.0.

Table 29 Descriptions for the MAC State Field

MAC State Value³

Description

Registration and Provisioning Status Conditions for Devices Using IPv4 Addressing

init(r1)

The CM sent initial ranging.

init(r2)

The CM is ranging. The CMTS received initial ranging from the Cm and has sent RF power, timing offset, and frequency adjustments to the CM.

init(rc)

Ranging has completed.

Note

If a CM appears to be stuck in this state, it could be that the CM is able to communicate successfully on the cable network, but that the upstream is at capacity and does not have any additional bandwidth to allow the CM to finish registration and come online. Either manually move one or more CMs to other upstreams, or enable load balancing on the upstream using the cable load-balance group commands.

init(d)

The DHCP request was received, as DHCPDISCOVER. This also indicates that the first IP broadcast packet has been received from the CM.

init(dr)

The DHCP request has been sent to the cable modem.

init(i)

The cable modem has received the DHCPOFFER reply (DHCPACK) from the DHCP server that has assigned an IP address to the modem, but the modem has not yet replied with a DHCPREQUEST message requesting that particular IP address, nor has it sent an IP packet with that IP address.

Note

If a CM appears to be stuck in this state, the CM has likely received the DHCPOFFER reply from the DHCP server, but this reply might have contained one or more invalid options for that particular CM.

init(io)

The Cisco CMTS has seen the DHCP offer as sent to the cable modem from the DHCP server that has assigned an IP address to the modem.

init(o)

The CM has begun to download the option file (DOCSIS configuration file) using the Trivial File Transfer Protocol (TFTP), as specified in the DHCP response. If the CM remains in this state, it indicates that the download has failed.

init(t)

Time-of-day (TOD) exchange has started.

resetting

The CM is being reset and will shortly restart the registration process.

Registration and Provisioning Status Conditions for Devices Using IPv6 Addressing

init6(s)

The Cisco CMTS router has seen the DHCPv6 SOLICIT message from the CM.

init6(a)

The Cisco CMTS router has seen the ADVERTISE message from the DHCPv6 server to the CM.

init6(r)

The Cisco CMTS router has seen the REQUEST response from the CM to the DHCPv6 server.

init6(i)

The Cisco CMTS router has seen the REPLY message from the DHCPv6 server to the CM.

init6(o)

The Cisco CMTS router has seen the REQEST message from the CM to the TFTP server.

init6(t)

The Cisco CMTS router has seen the REQUEST message from the CM to the TOD server.

Non-error Status Conditions

cc(r1)

The CM had registered and was online, but has received a Downstream Channel Change (DCC) or Upstream Channel Change (UCC) request message from the CMTS. The CM has begun moving to the new channel, and the CMTS has received the CM’s initial ranging on the new downstream or upstream channel. At the MAC layer, the CM is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

cc(r2)

This state should normally follow cc(r1) and indicates that the CM has finished its initial ranging on the new channel, and is currently performing continuous ranging on the new channel. At the MAC layer, the CM is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

offline

The CM is considered offline (disconnected or powered down).

online

The CM has registered and is enabled to pass data on the network.

online(d)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. The CM does not forward traffic to or from the CPE devices, but the CMTS can continue to communicate with the CM using DOCSIS messages and IP traffic (such as SNMP commands).

Note

If BPI was enabled in the DOCSIS configuration file sent to the CM, assume that the CM is using BPI encryption, unless other messages show that the BPI negotiation and key assignments have failed.

online(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and KEK is assigned.

Note

This state is equivalent to the online(d) and online(pk) states.

online(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

This state is equivalent to the online(d) and online(pt) states.

online(pk)

The CM registered, BPI is enabled and KEK is assigned.

online(pt)

The CM registered, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

If network access was disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) instead of online(pt) even when BPI encryption is enabled and operational.

Note

If an exclamation point (!) appears in front of one of the online states, it indicates that the cable dynamic-secret command has been used with either the mark or reject option, and that the cable modem has failed the dynamic secret authentication check.

expire(pk)

The CM registered, BPI is enabled, KEK was assigned, but the current KEK expired before the CM could successfully renew a new KEK value.

expire(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, KEK was assigned, but the current KEK expired before the CM could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pk) states.

expire(pt)

The CM registered, BPI is enabled, TEK was assigned, but the current TEK expired before the CM could successfully renew a new KEK value.

expire(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, TEK was assigned, but the current TEK expired before the CM could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pt) states.

Error Status Conditions

reject(m)

The CM attempted to register but registration was refused due to a bad Message Integrity Check (MIC) value. This also could indicate that the shared secret in the DOCSIS configuration file does not match the value configured on the CMTS with the cable shared-secret command.

In Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases, this could also indicate that the cable tftp-enforce command has been used to require that a CM attempt a TFTP download of the DOCSIS configuration file before registering, but the CM did not do so.

reject(c)

The CM attempted to register, but registration was refused due to a a number of possible errors:

The CM attempted to register with a minimum guaranteed upstream bandwidth that would exceed the limits imposed by the cable upstream admission-control command.
The CM has been disabled because of a security violation.
A bad class of service (COS) value in the DOCSIS configuration file.
The CM attempted to create a new COS configuration but the CMTS is configured to not permit such changes.
The CM failed the timestamp check for its DOCSIS configuration file. (This could indicate a possible theft-of-service attempt, or a problem with the synchronization of the clocks on the CM and CMTS.)

reject(pk)

KEK key assignment is rejected, BPI encryption has not been established.

reject(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because KEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pk) states.

reject(pt)

TEK key assignment is rejected, BPI encryption has not been established.

reject(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because TEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pt) states.

Note

In Cisco IOS Release 12.1(20)EC, Cisco IOS Release 12.2(15)BC1, and earlier releases, when network access is disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) even if BPI encryption fails. Use the show cable modemmac-address command to confirm whether BPI is enabled or disabled for a particular cable modem.

reject(ts)

The CM attempted to register, but registration failed because the TFTP server timestamp in the CM registration request did not match the timestamp maintained by the CMTS. This might indicate that the CM attempted to register by replaying an old DOCSIS configuration file used during a prior registration attempt.

reject(ip)

The CM attempted to register, but registration failed because the IP address in the CM request did not match the IP address that the TFTP server recorded when it sent the DOCSIS configuration file to the CM. IP spoofing could be occurring.

reject(na)

The CM attempted to register, but registration failed because the CM did not send a Registration-Acknowledgement (REG-ACK) message in reply to the Registration-Response (REG-RSP) message sent by the CMTS. A Registration-NonAcknowledgement (REG-NACK) is assumed.

³ The CM MAC state field can also be retrieved using SNMP by getting the value of the cdxCmtsCmStatusValue object in the CISCO-DOCS-EXT-MIB.

IOS-XE 3.15.0S	This command was implemented on the Cisco cBR Series Converged Broadband Router. The name keyword and logical-channel-index variable are removed.

Usage Guidelines

This command displays information about the number of times that a CM has exhausted its maximum retry attempts to respond to a Station Maintenance (SM) request, as well as the number of times that the CMTS has aborted ranging with a CM during a Station Maintenance interval. This information can be used to determine whether a particular cable modem or interface is experiencing plant or network difficulties.

You can display this information for all online cable modems, all online cable modems for a specific cable interface, or for one particular cable modem.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Syntax Description

ip-address	(Optional) IPv4 or IPv6 address of a specific CM to be displayed. If you specify the IP address for a CPE device behind a CM, information for that CM is displayed.
mac-address	(Optional) MAC address of a specific CM to be displayed. If you specify the MAC address for a CPE device behind a CM, information for that CM is displayed.
slot	Slot where the line card resides. Cisco uBR7225VXR router—The valid value is 1 or 2. Cisco uBR7246VXR router—The valid range is from 3 to 6. Cisco uBR10012 router—The valid range is from 5 to 8.
subslot	(Cisco uBR10012 only) Secondary slot number of the cable interface line card. The valid subslots are 0 or 1.
port	Downstream port number. Cisco uBR7225VXR and Cisco uBR7246VXR routers—The valid value is 0 or 1. Cisco uBR10012 router—The valid range is from 0 to 4 (depending on the cable interface).
cable-interface-index	Downstream port of the Cisco uBR10-MC5X20 and Cisco uBR-MC28 line cards, or MAC domain index of the Cisco UBR-MC20X20V and Cisco uBR-MC3GX60V line cards. Cisco uBR7225VXR and Cisco uBR7246VXR routers—The valid port value is 0 or 1. Cisco uBR10012 router—The valid range for the Cisco UBR-MC20X20V and Cisco uBR-MC5X20 line cards is from 0 to 4. The valid range for the Cisco uBR-MC3GX60V line card is from 0 to 14.
upstream port	(Optional) Displays information for all CMs using the specified upstream port. You can specify this option only when displaying information for a cable interface. The valid range for port begins with 0 and ends with a value that depends on the number of upstream ports supported by the cable interface line card.
logical-channel-index	(Optional) Logical channel index. The valid values are 0 or 1.
name fqdn	(Optional) Specifies the fully qualified domain name (FQDN) of the cable device to be displayed. This option is only available if the show cable modem domain-name command has been run for the first time to update the cable DNS cache on the CMTS router.
offline	Displays a list of the cable modems that are marked as offline.

Command Default

Displays a list of all offline CMs known by the Cisco CMTS router.

Command History

Release	Modification
12.0(7)XR and 12.1(1a)T1	This command was introduced.
12.2(4)BC1	Support for the Cisco uBR10012 router was introduced.
12.2(33)SCA	This command was integrated into Cisco IOS Release 12.2(33)SCA, with the following changes: Support for the Cisco uBR7225VXR router was added. Support for specifying the IPv6 address of a CM or CPE device was added. The name keyword option was added for specifying the fully-qualified domain name of a CM. The following new initialization states were added to show initialization of CMs and CPEs supporting IPv6: init6(s)—CMTS router has seen SOLICIT message. init6(a)—CMTS router has seen ADVERTISE message. init6(r)—CMTS router has seen REQUEST message. init6(i)—CMTS router has seen REPLY message. init6(o)—CMTS router has seen version 6 TFTP request. init6(t)—CMTS router has seen version 6 TOD request.
12.2(33)SCE	This command was modified. The port parameter was changed to cable-interface-index.
12.2(33)SCF	This command was modified. The logical-channel-index argument was added.
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR-8 Converged Broadband Router. All the keywords and variables were removed.

Usage Guidelines

This command displays a list of CMs that had either been online previously or had attempted to register with the CMTS, but that are now considered offline. Offline cable modems remain in the CMTS databases for 24 hours and then are deleted.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

MAC address

Hardware MAC address for this CM.

Prim SID

The primary SID that had been last assigned to this CM before it went offline.

Previous State

The last known state of the MAC layer for this CM before it went offline.

Note

A pound sign (#) in the Previous State column indicates that the cable tftp-enforce mark-only command has been used to require that a CM attempt a TFTP download of the DOCSIS configuration file before registering, but the CM did not do so (Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases).

Offline Time

The time and date that this CM last went offline.

Rx Power

The last known received power level (in dB) for the CM before it went offline.

Note

An asterisk (*) in the Rx Power column indicates that a power adjustment was made for that CM. An exclamation point (!) indicates that the CM had reached its maximum power transmit level and could not increase its power level further.

Rx SNR

The last known signal-to-noise ratio (SNR) value for this CM before it went offline.

SM Exhaust Count

Number of times that this CM has exhausted the maximum allowable retries for not responding to the regular Station Maintenance (SM) messages sent to it by the CMTS.

Note

Using the clear counters command to reset a cable interface’s counters also resets the SM Exhaust Count field for all offline CMs to zero and resets the Offline Time field for all offline CMs to the current time.

Table below shows the possible values for the Previous State field:

Table 33 Descriptions for the Previous State Field

MAC State Value ⁴

Description

Registration and Provisioning Status Conditions for Devices Using IPv4 Addressing

init(r1)

The CM sent initial ranging.

init(r2)

The CM is ranging. The CMTS received initial ranging from the Cm and has sent RF power, timing offset, and frequency adjustments to the CM.

init(rc)

Ranging has completed.

Note

If a CM appears to be stuck in this state, it could be that the CM is able to communicate successfully on the cable network, but that the upstream is at capacity and does not have any additional bandwidth to allow the CM to finish registration and come online. Either manually move one or more CMs to other upstreams, or enable load balancing on the upstream using the cable load-balance group commands.

init(d)

The DHCP request was received, as DHCPDISCOVER. This also indicates that the first IP broadcast packet has been received from the CM.

init(dr)

The DHCP request has been sent to the cable modem.

init(i)

The cable modem has received the DHCPOFFER reply (DHCPACK) from the DHCP server that has assigned an IP address to the modem, but the modem has not yet replied with a DHCPREQUEST message requesting that particular IP address, nor has it sent an IP packet with that IP address.

Note

If a CM appears to be stuck in this state, the CM has likely received the DHCPOFFER reply from the DHCP server, but this reply might have contained one or more invalid options for that particular CM.

init(io)

The Cisco CMTS has seen the DHCP offer as sent to the cable modem from the DHCP server that has assigned an IP address to the modem.

init(o)

The CM has begun to download the option file (DOCSIS configuration file) using the Trivial File Transfer Protocol (TFTP), as specified in the DHCP response. If the CM remains in this state, it indicates that the download has failed.

init(t)

Time-of-day (TOD) exchange has started.

resetting

The CM is being reset and will shortly restart the registration process.

Registration and Provisioning Status Conditions for Devices Using IPv6 Addressing

init6(s)

The Cisco CMTS router has seen the DHCPv6 SOLICIT message from the CM.

init6(a)

The Cisco CMTS router has seen the ADVERTISE message from the DHCPv6 server to the CM.

init6(r)

The Cisco CMTS router has seen the REQUEST response from the CM to the DHCPv6 server.

init6(i)

The Cisco CMTS router has seen the REPLY message from the DHCPv6 server to the CM.

init6(o)

The Cisco CMTS router has seen the REQEST message from the CM to the TFTP server.

init6(t)

The Cisco CMTS router has seen the REQUEST message from the CM to the TOD server.

Non-error Status Conditions

cc(r1)

The CM had registered and was online, but has received a Downstream Channel Change (DCC) or Upstream Channel Change (UCC) request message from the CMTS. The CM has begun moving to the new channel, and the CMTS has received the CM’s initial ranging on the new downstream or upstream channel. At the MAC layer, the CM is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

cc(r2)

This state should normally follow cc(r1) and indicates that the CM has finished its initial ranging on the new channel, and is currently performing continuous ranging on the new channel. At the MAC layer, the CM is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

offline

The CM is considered offline (disconnected or powered down).

online

The CM has registered and is enabled to pass data on the network.

online(d)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. The CM does not forward traffic to or from the CPE devices, but the CMTS can continue to communicate with the CM using DOCSIS messages and IP traffic (such as SNMP commands).

Note

If BPI was enabled in the DOCSIS configuration file sent to the CM, assume that the CM is using BPI encryption, unless other messages show that the BPI negotiation and key assignments have failed.

online(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and KEK is assigned.

Note

This state is equivalent to the online(d) and online(pk) states.

online(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

This state is equivalent to the online(d) and online(pt) states.

online(pk)

The CM registered, BPI is enabled and KEK is assigned.

online(pt)

The CM registered, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

If network access was disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) instead of online(pt) even when BPI encryption is enabled and operational.

Note

If an exclamation point (!) appears in front of one of the online states, it indicates that the dynamic-secret command has been used with either the mark or reject option, and that the cable modem has failed the dynamic secret authentication check.

expire(pk)

The CM registered, BPI is enabled, KEK was assigned, but the current KEK expired before the CM could successfully renew a new KEK value.

expire(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, KEK was assigned, but the current KEK expired before the CM could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pk) states.

expire(pt)

The CM registered, BPI is enabled, TEK was assigned, but the current TEK expired before the CM could successfully renew a new KEK value.

expire(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, TEK was assigned, but the current TEK expired before the CM could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pt) states.

Error Status Conditions

reject(m)

The CM attempted to register but registration was refused due to a bad Message Integrity Check (MIC) value. This also could indicate that the shared secret in the DOCSIS configuration file does not match the value configured on the CMTS with the cablecable shared-secret command.

In Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases, this could also indicate that the cable tftp-enforce command has been used to require that a CM attempt a TFTP download of the DOCSIS configuration file before registering, but the CM did not do so.

reject(c)

The CM attempted to register, but registration was refused due to a a number of possible errors:

The CM attempted to register with a minimum guaranteed upstream bandwidth that would exceed the limits imposed by the cable upstream admission-control command.
The CM has been disabled because of a security violation.
A bad class of service (COS) value in the DOCSIS configuration file.
The CM attempted to create a new COS configuration but the CMTS is configured to not permit such changes.
The CM failed the timestamp check for its DOCSIS configuration file. (This could indicate a possible theft-of-service attempt, or a problem with the synchronization of the clocks on the CM and CMTS.)

reject(pk)

KEK key assignment is rejected, BPI encryption has not been established.

reject(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because KEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pk) states.

reject(pt)

TEK key assignment is rejected, BPI encryption has not been established.

reject(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because TEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pt) states.

Note

In Cisco IOS Release 12.1(20)EC, Cisco IOS Release 12.2(15)BC1, and earlier releases, when network access is disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) even if BPI encryption fails. Use the show cable modem mac-address command to confirm whether BPI is enabled or disabled for a particular cable modem.

reject(ts)

The CM attempted to register, but registration failed because the TFTP server timestamp in the CM registration request did not match the timestamp maintained by the CMTS. This might indicate that the CM attempted to register by replaying an old DOCSIS configuration file used during a prior registration attempt.

reject(ip)

The CM attempted to register, but registration failed because the IP address in the CM request did not match the IP address that the TFTP server recorded when it sent the DOCSIS configuration file to the CM. IP spoofing could be occurring.

reject(na)

The CM attempted to register, but registration failed because the CM did not send a Registration-Acknowledgement (REG-ACK) message in reply to the Registration-Response (REG-RSP) message sent by the CMTS. A Registration-NonAcknowledgement (REG-NACK) is assumed.

⁴ The CM MAC state field can also be retrieved using SNMP by getting the value of the cdxCmtsCmStatusValue object in the CISCO-DOCS-EXT-MIB.

Command History

CX and BC Releases	Modification
12.1(4)CX and 12.2(4)BC1	This command was introduced for the Cisco uBR7100 series, Cisco uBR7200 series, and CIsco uBR10012 routers.
12.2(15)BC2	The service ID (SID) and Mode fields were added to the default display.
12.3(17a)BC	Enhanced the show cable modem phy command. The MicroReflec column (MicroReflections) has been removed, and the DOCSIS Prov (DOCSIS Provider) column has been added in its place. This new column contains DOCSIS version information. See updated examples.
SC Release	Modification
12.2(33)SCA	This command was integrated into Cisco IOS Release 12.2(33)SCA, with the following changes: Support for the Cisco uBR7225VXR router was added. Support for specifying the IPv6 address of a CM or CPE device was added. The name keyword option was added for specifying the fully-qualified domain name of a CM.
12.2(33)SCC	For DOCSIS 3.0-certified cable modems with multiple upstream channels, the command output was modified to display PHY layer details of each upstream channel. In this case, the output may contain multiple results for the same MAC address. The asterix (*) that appears beside the DOCSIS operating mode under the Mode column identifies that the CM is operating in the MTC mode.
12.2(33)SCE	This command was modified. The port parameter was changed to cable-interface-index.
12.2(33)SCF	This command was modified. The logical-channel-index argument was added.
Cisco cBR-8 Converged Broadband Router
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR-8 Converged Broadband Router. The upstream and name keywords were removed. The logical-channel-index is removed.
Cisco IOS XE Everest 16.6.1	This command was modified. The ofdma keyword was added.

Usage Guidelines

This command displays information about the DOCSIS PHY layer for one or more CMs. You can display information for all CMs, for all CMs on a particular cable interface, or for a particular CM, as identified by its IP or MAC address.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Table below describes the fields shown in the show cable modem phy displays:

Table 36 Descriptions for the show cable modem phy fields

Field

Description

MAC Address

The MAC address for the CM.

I/F

The cable interface on the CMTS that is providing services for this CM.

SID

Service ID that this CM is using.

USPwr (dBmV)

Displays the CM transmit level in dBmV, as measured by the CMTS.

USSNR (dBmV)

Upstream signal-to-noise ratio (SNR) or carrier-to-noise ratio (CNR), in dB, as measured by the CMTS. This field shows the CNR value for cable interfaces that support onboard hardware-based spectrum management, such as the Cisco uBR-MC16S card, and shows the SNR value for other cable interfaces.

Note

Although the field name shows the value as being given in dBmV, the actual value should be interpreted in dB.

Timing Offset

The timing offset for the CM, in ticks, as recognized on the CMTS. (A tick, as used here, is 6.25/64 microseconds.) This is the delay between when a particular cable modem is scheduled to make a transmission and when the CMTS actually receives it.

Note

An exclamation point (!) in the Timing Offset column indicates that the CM has exceeded the maximum delay and timing offset specified by the cable map-advance command.

Note

The timing offset shown here is typically smaller than the TX Time Offset value shown by the show cable modem remote-query command, because the latter value is the offset as recognized on the CM (which will include any internal delay between when the CM software begins the transmission and when the bits actually appear on the local cable interface).

Microreflec (dBc)

The approximate value of microreflections on the downstream, measured in dBc below the signal level, as seen by the CM. Microreflections are a type of impairment that is caused by impedance mismatches between amplifiers, couples, cables, and other equipment in the cable plant. Microreflections create copies of a signal that arrive at the receiver with different amounts of delay and attenuation, generating intersymbol interference (ISI) that can cause the receiver to improperly detect the amplitude and phase of the incoming signal.

Note

This value is not exact but provides an approximate indication of the microreflections that have been received.

DSPwr (dBmV)

Downstream receive power level, in dBmV, as reported by the CM.

DSSNR (dBmV)

Note

This command displays values for the downstream power and SNR values only if you have configured the cable modem remote-query command on the CMTS, and if the CM supports providing those options.

Downstream signal-to-noise ratio (SNR), in dB, as reported by the CM.

Mode

DOCSIS operating mode for the CM:

tdma=DOCSIS 1.X, TDMA-only mode
atdma=DOCSIS 2.0 A-TDMA mode

A hyphen (-) indicates the mode is unknown or the CM has not yet registered.

For DOCSIS 3.0-certified cable modems with multiple upstream channels, the output may contain multiple results for the same MAC address. In Cisco IOS Release 12.2(33)SCC, the asterix (*) that appears beside the DOCSIS operating mode under the Mode column identifies that the CM is operating in the MTC mode.

Note

This field is the same as that returned by the docsIfCmtsCmStatusModulationType object in the DOCS-IF-MIB.

Command	Description
show controllers integrated-cable rf-channel prof-order	Displays information about the profile downgrade ordering on a given OFDM channel.
show cable modem phy ofdm-profile	Displays information about the profiles associated with the cable modems (CMs).

show cable modem qos

To display the quality of service (QoS) and service flow information for a particular cable modem (CM), use the show cable modem qos command in privileged EXEC mode.

show cable modem { ip-address | mac-address | name fqdn } qos [ service-class | verbose ]

Cisco cBR-8 Converged Broadband Router

show cable modem { ip-address | mac-address } qos [ service-class | verbose ]

Syntax Description

ip-address	IPv4 or IPv6 address of a specific CM to be displayed. If you specify the IP address for a CPE device behind a CM, information for that CM is displayed.
mac-address	MAC address of a specific CM to be displayed. If you specify the MAC address for a CPE device behind a CM, information for that CM is displayed.
name fqdn	(Optional) Specifies the fully qualified domain name (FQDN) of the cable device to be displayed. This option is only available if the show cable modem domain-name command has been run for the first time to update the cable DNS cache on the CMTS router. This option is not supported on the Cisco cBR-8 router.
service-class	(Optional) Displays the service class names associated with each service flow for a specific cable modem.
verbose	(Optional) Displays detailed information for each service flow ID (SFID) for the CM.

Command History

Release	Modification
11.3XA	This command was introduced.
12.2(33)SCA	This command was integrated into Cisco IOS Release 12.2(33)SCA, with the following changes: Support for the Cisco uBR7225VXR router was added. Support for specifying the IPv6 address of a CM or CPE device was added. The name keyword option was added for specifying the fully-qualified domain name of a CM.
12.2(33)SCC	The command output was modified to display the traffic peak rate value for a specific service flow.
12.2(33)SCF	This command was modified. The service-class keyword was added to display the service class names for each service flow for a specific cable modem.
12.2(33)SCG	The command output was modified to display the scheduling type as “N/A” for all downstream service flows.
12.2(33)SCI1	The command output was modified to display the IP ToS Overwrite [AND-mask, OR-mask] for the downstream service flow.
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR-8 Converged Broadband Router. The name variable was removed.

Usage Guidelines

This command displays the service flows currently in use by a CM. The default form of the display shows one service flow per line, while the verbose keyword displays complete information for each flow.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Note

Starting with Cisco IOS Release 12.2(33)SCG, the output of the show cable modem qos command displays the scheduling type of all downstream service flows (DS-SF) as “N/A” to indicate that the DS-SFs do not have any scheduling type.

Usage Guidelines

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

The following example shows sample output for the default form of the show cable modem registered command in Cisco IOS Release 12.2(33)SCA:

Note

An asterisk (*) in the Receive Power column indicates that a power adjustment has been made for that CM. An exclamation point (!) in the Receive Power column indicates that the CM has reached its maximum power transmit level and cannot increase its power level further. An exclamation point (!) in the Timing Offset column indicates that the CM has exceeded the maximum delay and timing offset specified by the cable map-advance command. A pound sign (#) in the MAC State column indicates that the cable tftp-enforce mark-only command has been used to require that a CM attempt a TFTP download of the DOCSIS configuration file before registering, but the CM did not do so (Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases).

Tip

The show cable modem command displays the CM timing offset in DOCSIS ticks, while other commands, such as cable map-advance, display the offset in microseconds. Use the following method to convert microseconds to DOCSIS ticks: ticks = microseconds*64/6.25 .

Table below describes the major fields shown in the show cable modem registered displays:

Table 40 Descriptions for the show cable modem registered Fields

Field

Description

Interface

The cable interface line card providing the upstream for this CM.

Prim SID

The primary SID assigned to this CM.

Online State

The current state of the MAC layer. Should show “online” for registered CMs.

Timing Offset

The timing offset for the CM, in ticks, as recognized on the CMTS. (A tick, as used here, is 6.25/64 microseconds.) This is the delay between when a particular cable modem is scheduled to make a transmission and when the CMTS actually receives it.

Note

An exclamation point (!) in the Timing Offset column indicates that the CM has exceeded the maximum delay and timing offset specified by the cable map-advance command.

Note

The timing offset shown here is typically smaller than the TX Time Offset value shown by the show cable modem remote-query command, because the latter value is the offset as recognized on the CM (which will include any internal delay between when the CM software begins the transmission and when the bits actually appear on the local cable interface).

Rec Power

The received power level (in dB) for the CM.

Note

An asterisk (*) in the RxPwr column indicates that a power adjustment has been made for that CM. An exclamation point (!) indicates that the CM has reached its maximum power transmit level and cannot increase its power level further.

QoS

Displays the QoS profile assigned to the CM (DOCSIS 1.1 and DOCSIS 2.0 CMs only).

CPE

Indicates the number of CPE devices for which the CM is providing services.

IP Address

The IP address that the DHCP server has assigned to the CM.

MAC Address

The MAC address for the CM.

The following examples show the output of the show cable modem registered command with specific IP Address, MAC Address and cable interface.

Table below shows the fields displayed by the show cable modem remote-query command.

Table 41 Descriptions for the show cable modem remote-query Fields

Field

Description

IP Address

The IP address that the DHCP server has assigned to the CM.

MAC Address

The MAC address for the CM.

S/N Ratio

The current signal-to-noise ratio (SNR) on the downstream, as seen by the CM.

US Power

The current operational transmit power level, in dBmV, as seen by the CM.

DS Power

The received power level, in dBmV, as seen by the CM. This field is set to zero if the CM does not support power level measurements.

TX Time Offset

The timing offset for the CM, in ticks, as recognized on the CM. (A tick, as used here, is 6.25/64 microseconds.) This is the delay between when a particular cable modem is scheduled to make a transmission and when the CMTS actually receives it. The CM value includes any internal delay between when the CM software begins the transmission and when the bits actually appear on the local cable interface.

Note

The timing offset shown here is typically larger than the Time Offset value shown by the show cable modem command, because the latter value is the offset as recognized on the CMTS (which does not include the internal delay on the CM).

Micro (dB) Reflection

The approximate number of total microreflections (including in-channel responses) on the downstream, measured in dBc below the signal level, as seen by the CM. Microreflections are a type of impairment that is caused by impedance mismatches between amplifiers, couples, cables, and other equipment in the cable plant. Microreflections create copies of a signal that arrive at the receiver with different amounts of delay and attenuation, generating intersymbol interference (ISI) that can cause the receiver to improperly detect the amplitude and phase of the incoming signal.

Note

This value is not exact but provides an approximate indication of the microreflections that have been received.

Modem State

The current state of the MAC layer for the CM.

Command History

Release	Modification
12.2(15)BC1	This command was introduced for Cisco uBR7100 series, Cisco uBR7200 series, and Cisco uBR10012 routers.
12.2(33)SCA	This command was integrated into Cisco IOS Release 12.2(33)SCA, with the following changes: Support for the Cisco uBR7225VXR router was added. Support for specifying the IPv6 address of a CM or CPE device was added. The name keyword option was added for specifying the fully-qualified domain name of a CM.
12.2(33)SCE	This command was modified. The port parameter was changed to cable-interface-index.
12.2(33)SCF	This command was modified. The logical-channel-index argument was added.
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR-8 Converged Broadband Router. The upstream and name keywords, and the logical-channel-index variable were removed.

Usage Guidelines

This command displays a list of cable modems that attempted to register with a DOCSIS configuration file that does not pass the authentication required by the cable dynamic-secret command. After a cable modem is added to the rogue list, it remains in the rogue list until one of the following occurs:

The cable modem remains offline, without attempting to reregister, for 24 hours. It is then removed from all of the CMTS internal databases, including the rogue list.
An administrator manually deletes the cable modem from the CMTS internal databases, using the clear cable modem delete command.
An administrator unlocks the cable modem using the clear cable modem lock command.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

show cable modem select [ mac| ip]

Syntax Description

ip

Specifies the IPv4 address of a specific CM to be displayed.

mac

Identifies the MAC address of a specific CM to be displayed.

ipv6

IPv6 address of the cable modem to be displayed.

intf

Name of the host interface.

dip

Dual IP Support of dual IP for both IPv4 and IPv6 addressing.

sid

Primary SID assigned to this CM.

st

Displays cable modem status events.

dssg

MD-DS-SG for cable modem.

ussg

MD-US-SG for cable modem.

cmsg

MD-CM-SG for cable modem.

mtc

Multi-Transmit Channel Mode. Cable modem is in MTC mode or not.

macver

Displays the maximum supported version of DOCSIS that the cable modem supports (DOCSIS 1.0, DOCSIS 1.1, DOCSIS 2.0, DOCSIS 3.01).

show cable modem service-flow

To display information about all service flows associated with a particular modem, use the show cable modem service-flow command in privileged EXEC mode.

show cable modem { ip-address | mac-address } service-flow [ verbose | ds-hardware ]

Cisco cBR-8 Converged Broadband Router

show cable modem { ip-address | mac-address } service-flow [ verbose | ds-hardware | upstream ]

Syntax Description

ip-address	Specifies the IPv4 address of a specific CM to be displayed. If you specify the IP address for a CPE device behind a CM, information for that CM is displayed.
mac-address	Identifies the MAC address of a specific CM to be displayed. You can also specify the MAC address for a CPE device behind a CM, and information for that CM will be displayed.
service-flow	Displays summary of relevant parameters and statistics for all service flows associated with a particular modem.
verbose	(Optional) Displays comprehensive details for all service flows associated with a particular modem. In addition, it displays the active cable-filter group for the cable modem.
ds-hardware	(Optional) Displays details of Baseline Privacy Interface (BPI), Payload Header Suppression (PHS), Downstream Service Identifier (DSID) and other statistical data.
upstream	Displays summary of relevant parameters and statistics for upstream service flows with a particular modem for a Cisco cBR-8 router.

12.2(33)SCB1	This command was introduced for Cisco uBR7200 series and Cisco uBR10012 routers in Cisco IOS Release 12.2(33)SCB1.
12.3(23)BC7	This command was integrated into Cisco IOS Release 12.3(23)BC7.
12.2(33)SCE	This command was modified. The ds-hardware keyword was added.
12.2(33)SCF2	This command was modified. The command output was enhanced to display upstream buffer control parameters.
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR-8 Converged Broadband Router. The upstream keyword was added.
IOS-XE 3.18.1SP	This command was modified. The command output for the verbose option was enhanced to display the active cable filter groups for the cable modem.

Usage Guidelines

The show cable modem service-flow command has a verbose and a non-verbose option. The non-verbose command supports live debugging and provides a summary of relevant parameters and statistics for all service flows of a particular modem. The verbose option of the command provides comprehensive details for all service flows associated with a particular modem.

The optional ds-hardware keyword is used to display per service flow BPI, PHS, DSID and stats data obtained directly from the hardware on the line card or SPA.

Note

The output data for unconfigured or non applicable features are not always displayed.

Examples

The following is a sample output of the show cable modem service-flow command without the verbose option:

Router# show cable modem 40.30.0.5 service-flow

Command History

Release	Modification
12.2(33)SCG2	This command was introduced.
12.2(33)SCH 12.2(33)SCG5	This command is supported for IPv6 cable modems.
12.2(33)SCH	This command was modified. The variable ipv6-address was added for IPv6 support.
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR-8 Converged Broadband Router.

Usage Guidelines

You must enable the Simple Network Management Protocol (SNMP) manager process using the snmp-server manager command in global configuration mode before using the show cable modem sysDescr command. The show cable modem sysDescr command displays result for IPv4 cable modems only.

Note

Effective with Cisco IOS Release 12.2(33)SCH and 12.2(33)SCG5, the show cable modem sysDescr command displays results for IPv6 cable modems.

In Cisco IOS Release 12.2(33)SCG1 and earlier, you cannot view the system description of a single cable modem. Instead, you can view system descriptions of all the cable modems connected to the Ciso CMTS router. To view the system descriptions of all cable modems, enable the remote-query functionality on the Cisco CMTS router using the cable modem remote-query command in global configuration mode. Then, run the show cable modem verbose | include sysDescr command.

Note

The remote-query functionality might impact system performance because it queries all the cable modems connected to the Cisco CMTS router.

A community name string is configured in the CMTS for the cable modems using the snmp-server communitycommunity-string command or by enabling the cable modem remote-query feature using the cable modem remote-query community-string command.

The CMTS uses the default community name public if you do not specify the community option when you use the show cable modem sysDescr command.

Note

Ensure that the community-name specified in the show cable modem sysDescr command matches the community name configured in the cable modem's configuration file. Also ensure that public is configured as a community name in the cable modem configuration file in case you do not specify the community string in this show command.

If the community name specified in this show command does not match the community names configured in the cable modem's configuration file , then the show cable modem sysDescr command output does not provide any system description and the output is as follows:

Router#show cable modem 602a.d001.faa0 sysdescr
Querying remote CM...
Timeout

Examples

The following is a sample output of the show cable modem sysDescr command that displays system description of the specified cable modem:

Router# show cable modem 001c.ea37.9b52 sysDescr
Querying remote CM...

Usage Guidelines

Operation with Hot Standby Connection-to-Connection Protocol (HCCP) Configuration

If you are using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1) redundancy, the new primary processor after a switchover automatically creates a new database of the online cable modems. This means that the show cable modem ip-address command might not show a particular cable modem until the CMTS receives IP traffic from that cable modem. You can force IP traffic by using the ping ip-address command, and then the show cable modem ip-address command will show the cable modem. You can also display any particular cable modem by using the show cable modem | include ip-address command.

In addition, when HCCP redundancy has been configured, the Cisco IOS software automatically synchronizes the secondary, backup cards whenever the configuration is changed. The cards can also be synchronized manually, using the hccp resync command. When a SYNC event command is occurring, CLI commands might be very slow to respond. In particular, if you enter the show cable modem command at the same time a SYNC event is occurring, the command might respond produce a blank display, or it might display an error message similar to the following:

%No response from slot 6/1. Command aborted

If this occurs, wait a minute or so and retry the command.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Note

In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.

Note

An asterisk (*) in the Receive Power column indicates that a power adjustment has been made for that CM. An exclamation point (!) in the Receive Power column indicates that the cable modem has reached its maximum power transmit level and cannot increase its power level further. An exclamation point (!) in the Timing Offset column indicates that the cable modem has exceeded the maximum delay and timing offset specified by the cable map-advance command. A pound sign (#) in the MAC State column indicates that the cable tftp-enforce mark-only command has been used to require that a cable modem attempt a TFTP download of the DOCSIS configuration file before registering, but the cable modem did not do so (Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases).

Tip

The show cable modem command displays the cable modem timing offset in DOCSIS ticks, while other commands, such as cable map-advance, display the offset in microseconds. Use the following method to convert microseconds to DOCSIS ticks: ticks = microseconds*64/6.25 .

Table below describes the major fields shown in the show cable modem unregistered displays:

Table 51 Descriptions for the show cable modem unregistered Fields

Field

Description

Interface

The cable interface line card providing the upstream for this CM.

Prim SID

The primary SID assigned to this CM.

Online State

The current state of the MAC layer.

Timing Offset

The timing offset for the cable modem, in ticks, as recognized on the CMTS. (A tick, as used here, is 6.25/64 microseconds.) This is the delay between when a particular cable modem is scheduled to make a transmission and when the CMTS actually receives it.

Note

An exclamation point (!) in the Timing Offset column indicates that the cable modem has exceeded the maximum delay and timing offset specified by the cable map-advance command.

Note

The timing offset shown here is typically smaller than the TX Time Offset value shown by the show cable modem remote-query command, because the latter value is the offset as recognized on the cable modem (which will include any internal delay between when the cable modem software begins the transmission and when the bits actually appear on the local cable interface).

Rec Power

The received power level (in dB) for the CM.

Note

An asterisk (*) in the RxPwr column indicates that a power adjustment has been made for that CM. An exclamation point (!) indicates that the cable modem has reached its maximum power transmit level and cannot increase its power level further.

QoS

Displays the QoS profile assigned to the cable modem (DOCSIS 1.1 and DOCSIS 2.0 CMs only).

CPE

Indicates the number of CPE devices for which the cable modem is providing services.

IP Address

The IP address that the DHCP server has assigned to the CM.

MAC Address

The MAC address for the CM.

Table below shows the possible values for the Online State field:

Table 52 Descriptions for the Online State Field

MAC State Value⁵

Description

Registration and Provisioning Status Conditions for Devices Using IPv4 Addressing

init(r1)

The cable modem sent initial ranging.

init(r2)

The cable modem is ranging. The CMTS received initial ranging from the cable modem and has sent RF power, timing offset, and frequency adjustments to the CM.

init(rc)

Ranging has completed.

Note

If a cable modem appears to be stuck in this state, it could be that the cable modem is able to communicate successfully on the cable network, but that the upstream is at capacity and does not have any additional bandwidth to allow the cable modem to finish registration and come online. Either manually move one or more CMs to other upstreams, or enable load balancing on the upstream using the cable load-balance group commands.

init(d)

The DHCP request was received, as DHCPDISCOVER. This also indicates that the first IP broadcast packet has been received from the CM.

init(dr)

The DHCP request has been sent to the cable modem.

init(i)

The cable modem has received the DHCPOFFER reply (DHCPACK) from the DHCP server that has assigned an IP address to the modem, but the modem has not yet replied with a DHCPREQUEST message requesting that particular IP address, nor has it sent an IP packet with that IP address.

Note

If a cable modem appears to be stuck in this state, the cable modem has likely received the DHCPOFFER reply from the DHCP server, but this reply might have contained one or more invalid options for that particular CM.

init(io)

The Cisco CMTS has seen the DHCP offer as sent to the cable modem from the DHCP server that has assigned an IP address to the modem.

init(o)

The cable modem has begun to download the option file (DOCSIS configuration file) using the Trivial File Transfer Protocol (TFTP), as specified in the DHCP response. If the cable modem remains in this state, it indicates that the download has failed.

init(t)

Time-of-day (TOD) exchange has started.

resetting

The cable modem is being reset and will shortly restart the registration process.

Registration and Provisioning Status Conditions for Devices Using IPv6 Addressing

init6(s)

The Cisco CMTS router has seen the DHCPv6 SOLICIT message from the CM.

init6(a)

The Cisco CMTS router has seen the ADVERTISE message from the DHCPv6 server to the CM.

init6(r)

The Cisco CMTS router has seen the REQUEST response from the cable modem to the DHCPv6 server.

init6(i)

The Cisco CMTS router has seen the REPLY message from the DHCPv6 server to the CM.

init6(o)

The Cisco CMTS router has seen the REQEST message from the cable modem to the TFTP server.

init6(t)

The Cisco CMTS router has seen the REQUEST message from the cable modem to the TOD server.

Non-error Status Conditions

cc(r1)

The cable modem had registered and was online, but has received a Downstream Channel Change (DCC) or Upstream Channel Change (UCC) request message from the CMTS. The cable modem has begun moving to the new channel, and the CMTS has received the CM’s initial ranging on the new downstream or upstream channel. At the MAC layer, the cable modem is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

cc(r2)

This state should normally follow cc(r1) and indicates that the cable modem has finished its initial ranging on the new channel, and is currently performing continuous ranging on the new channel. At the MAC layer, the cable modem is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

offline

The cable modem is considered offline (disconnected or powered down).

online

The cable modem has registered and is enabled to pass data on the network.

online(d)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. The cable modem does not forward traffic to or from the CPE devices, but the CMTS can continue to communicate with the cable modem using DOCSIS messages and IP traffic (such as SNMP commands).

Note

If BPI was enabled in the DOCSIS configuration file sent to the cable modem, assume that the cable modem is using BPI encryption, unless other messages show that the BPI negotiation and key assignments have failed.

online(pkd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and KEK is assigned.

Note

This state is equivalent to the online(d) and online(pk) states.

online(ptd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

This state is equivalent to the online(d) and online(pt) states.

online(pk)

The cable modem registered, BPI is enabled and KEK is assigned.

online(pt)

The cable modem registered, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

If network access was disabled in the DOCSIS configuration file sent to the cable modem, the network disabled status takes precedence, and the MAC status field shows online(d) instead of online(pt) even when BPI encryption is enabled and operational.

Note

If an exclamation point (!) appears in front of one of the online states, it indicates that the cable dynamic-secret command has been used with either the mark or reject option, and that the cable modem has failed the dynamic secret authentication check.

expire(pk)

The cable modem registered, BPI is enabled, KEK was assigned, but the current KEK expired before the cable modem could successfully renew a new KEK value.

expire(pkd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, KEK was assigned, but the current KEK expired before the cable modem could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pk) states.

expire(pt)

The cable modem registered, BPI is enabled, TEK was assigned, but the current TEK expired before the cable modem could successfully renew a new KEK value.

expire(ptd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, TEK was assigned, but the current TEK expired before the cable modem could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pt) states.

Error Status Conditions

reject(m)

The cable modem attempted to register but registration was refused due to a bad Message Integrity Check (MIC) value. This also could indicate that the shared secret in the DOCSIS configuration file does not match the value configured on the CMTS with the cable shared-secret command.

In Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases, this could also indicate that the cable tftp-enforce command has been used to require that a cable modem attempt a TFTP download of the DOCSIS configuration file before registering, but the cable modem did not do so.

reject(c)

The cable modem attempted to register, but registration was refused due to a a number of possible errors:

The cable modem attempted to register with a minimum guaranteed upstream bandwidth that would exceed the limits imposed by the cable upstream admission-control command.
The cable modem has been disabled because of a security violation.
A bad class of service (COS) value in the DOCSIS configuration file.
The cable modem attempted to create a new COS configuration but the CMTS is configured to not permit such changes.
The cable modem failed the timestamp check for its DOCSIS configuration file. (This could indicate a possible theft-of-service attempt, or a problem with the synchronization of the clocks on the cable modem and CMTS.)

reject(pk)

KEK key assignment is rejected, BPI encryption has not been established.

reject(pkd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because KEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pk) states.

reject(pt)

TEK key assignment is rejected, BPI encryption has not been established.

reject(ptd)

The cable modem registered, but network access for CPE devices using this cable modem has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because TEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pt) states.

Note

In Cisco IOS Release 12.1(20)EC, Cisco IOS Release 12.2(15)BC1, and earlier releases, when network access is disabled in the DOCSIS configuration file sent to the cable modem, the network disabled status takes precedence, and the MAC status field shows online(d) even if BPI encryption fails. Use the show cable modem mac-address command to confirm whether BPI is enabled or disabled for a particular cable modem.

reject(ts)

The cable modem attempted to register, but registration failed because the TFTP server timestamp in the cable modem registration request did not match the timestamp maintained by the CMTS. This might indicate that the cable modem attempted to register by replaying an old DOCSIS configuration file used during a prior registration attempt.

reject(ip)

The cable modem attempted to register, but registration failed because the IP address in the cable modem request did not match the IP address that the TFTP server recorded when it sent the DOCSIS configuration file to the CM. IP spoofing could be occurring.

reject(na)

The cable modem attempted to register, but registration failed because the cable modem did not send a Registration-Acknowledgement (REG-ACK) message in reply to the Registration-Response (REG-RSP) message sent by the CMTS. A Registration-NonAcknowledgement (REG-NACK) is assumed.

⁵ The cable modem MAC state field can also be retrieved using SNMP by getting the value of the cdxCmtsCmStatusValue object in the CISCO-DOCS-EXT-MIB.

Note

For the complete list of the cable modem status, see Table 2.

Tip

The show cable modem vendor command displays the CM timing offset in DOCSIS ticks, while other commands, such as cable map-advance, display the offset in microseconds. Use the following method to convert microseconds to DOCSIS ticks: ticks = microseconds*64/6.25 .

Table below describes the major fields shown in the show cable modem vendor displays:

Table 53 Descriptions for the show cable modem vendor Fields

Field

Description

Vendor

The vendor name for the indicated CM, as specified by the cable modem vendor command. If no name for this vendor has been specified, displays the modem’s OUI value.

MAC Address

The MAC address for the CM.

I/F

The cable interface line card providing the upstream for this CM.

MAC State

The current state of the MAC layer.

Prim SID

The primary SID assigned to this CM.

RxPwr

The received power level (in dB) for the CM.

Note

An asterisk (*) in the RxPwr column indicates that a power adjustment has been made for that CM. An exclamation point (!) indicates that the CM has reached its maximum power transmit level and cannot increase its power level further.

Note

RxPwr field is not supported on Cisco cBR-8 router.

Timing Offset

The timing offset for the CM, in ticks, as recognized on the CMTS. (A tick, as used here, is 6.25/64 microseconds.) This is the delay between when a particular cable modem is scheduled to make a transmission and when the CMTS actually receives it.

Note

An exclamation point (!) in the Timing Offset column indicates that the CM has exceeded the maximum delay and timing offset specified by the cable map-advance command.

Note

The timing offset shown here is typically smaller than the TX Time Offset value shown by the show cable modem remote-query command, because the latter value is the offset as recognized on the CM (which will include any internal delay between when the CM software begins the transmission and when the bits actually appear on the local cable interface).

Note

Timing Offset field is not supported on Cisco cBR-8 router.

Num CPE

Indicates the number of CPE devices for which the CM is providing services.

BPI Enbld

Indicates whether Baseline Privacy Interface (BPI) or BPI Plus (BPI+) encryption is enabled for the CM.

Note

An asterisk (*) in the RxPwr column indicates that a power adjustment has been made for that CM. An exclamation point (!) in the Receive Power column indicates that the CM has reached its maximum power transmit level and cannot increase its power level further. An exclamation point (!) in the Timing Offset column indicates that the CM has exceeded the maximum delay and timing offset specified by the cable map-advance command. A pound sign (#) in the MAC State column indicates that the cable tftp-enforce mark-only command has been used to require that a CM attempt a TFTP download of the DOCSIS configuration file before registering, but the CM did not do so (Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases).

The following example shows typical output for the show cable modem vendor summary command, displaying the total numbers for each vendor and OUI, along with the total numbers of those vendor’s CMs that are currently registered with the CMTS, unregistered, or offline.

Command History

Release	Modification
12.3(21)BC	This command was introduced for the Cisco uBR10012 universal broadband router.
12.2(33)SCA	This command was integrated into Cisco IOS Release 12.2(33)SCA.
12.2(33)SCB	This command output no longer shows the downstream (DS) channel ID or the bonding group (BG) ID. A new column was added to display the Receive Channel Configuration (RCC) ID of the RCC assigned to the cable modem.
12.2(33)SCE	This command was modified. The port parameter was changed to cable-interface-index.
12.2(33)SCF	This command was modified. The channel keyword and logical-channel-index argument was added.
12.2(33)SCG	This command output was modified to display direct downstream and upstream channel information on downstream channel bonding (DSCB) and upstream channel bonding (USCB) partial services.
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR Series Converged Broadband Routers. The logical-channel-index variable was removed.
IOS-XE 3.18.1SP	This command was modified. The forwarding-summary argument was added.

Usage Guidelines

This command displays information for a one or more wideband CMs. Optionally, the CMs for which to display information can be identified IP address, MAC address, or cable interface.

If a wideband-capable CM is not able to register as a wideband CM (for example, if no wideband channel is available), the CM attempts to register as a traditional DOCSIS modem. The registered-traditional-docsis keyword limits the set of wideband CMs for which to display information to wideband-capable CMs that are currently registered as DOCSIS 1.X or DOCSIS 2.0 modems.

Table below shows the possible values for the MAC State field for a wideband CM modem that registers as a traditional DOCSIS modem:

Table 55 Descriptions for the MAC State Field (for Traditional DOCSIS Modems)

MAC State Value ⁶

Description

Registration and Provisioning Status Conditions

init(r1)

The CM sent initial ranging.

init(r2)

The CM is ranging. The CMTS received initial ranging from the CM and has sent RF power, timing offset, and frequency adjustments to the CM.

init(rc)

Ranging has completed.

Note

If a CM appears to be stuck in this state, it could be that the CM is able to communicate successfully on the cable network, but that the upstream is at capacity and does not have any additional bandwidth to allow the CM to finish registration and come online. Either manually move one or more CMs to other upstreams, or enable load balancing on the upstream using the cable load-balance commands.

init(d)

The DHCP request was received, as DHCPDISCOVER. This also indicates that the first IP broadcast packet has been received from the CM.

init(dr)

The DHCP request has been sent to the cable modem.

init(i)

The cable modem has received the DHCPOFFER reply (DHCPACK) from the DHCP server that has assigned an IP address to the modem, but the modem has not yet replied with a DHCPREQUEST message requesting that particular IP address, nor has it sent an IP packet with that IP address.

Note

If a CM appears to be stuck in this state, the CM has likely received the DHCPOFFER reply from the DHCP server, but this reply might have contained one or more invalid options for that particular CM.

init(io)

The Cisco CMTS has seen the DHCP offer as sent to the cable modem from the DHCP server that has assigned an IP address to the modem.

init(o)

The CM has begun to download the option file (DOCSIS configuration file) using the Trivial File Transfer Protocol (TFTP), as specified in the DHCP response. If the CM remains in this state, it indicates that the download has failed.

init(t)

Time-of-day (TOD) exchange has started.

resetting

The CM is being reset and will shortly restart the registration process.

Non-error Status Conditions

cc(r1)

The CM had registered and was online, but has received a Downstream Channel Change (DCC) or Upstream Channel Change (UCC) request message from the CMTS. The CM has begun moving to the new channel, and the CMTS has received the CM’s initial ranging on the new downstream or upstream channel. At the MAC layer, the CM is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

cc(r2)

This state should normally follow cc(r1) and indicates that the CM has finished its initial ranging on the new channel, and is currently performing continuous ranging on the new channel. At the MAC layer, the CM is considered offline because it is not yet passing traffic on the new channel, but this state does not trigger the flap-list counters.

offline

The CM is considered offline (disconnected or powered down).

online

The CM has registered and is enabled to pass data on the network.

online(d)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. The CM does not forward traffic to or from the CPE devices, but the CMTS can continue to communicate with the CM using DOCSIS messages and IP traffic (such as SNMP commands).

Note

If BPI was enabled in the DOCSIS configuration file sent to the CM, assume that the CM is using BPI encryption, unless other messages show that the BPI negotiation and key assignments have failed.

online(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and KEK is assigned.

Note

This state is equivalent to the online(d) and online(pk) states.

online(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

This state is equivalent to the online(d) and online(pt) states.

online(pk)

The CM registered, BPI is enabled and KEK is assigned.

online(pt)

The CM registered, BPI is enabled and TEK is assigned. BPI encryption is now being performed.

Note

If network access was disabled in the DOCSIS configuration file sent to the CM, the network disabled status takes precedence, and the MAC status field shows online(d) instead of online(pt) even when BPI encryption is enabled and operational.

Note

If an exclamation point (!) appears in front of one of the online states, it indicates that the cable dynamic-secret command has been used with either the mark or reject option, and that the cable modem has failed the dynamic secret authentication check

expire(pk)

The CM registered, BPI is enabled, KEK was assigned, but the current KEK expired before the CM could successfully renew a new KEK value.

expire(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, KEK was assigned, but the current KEK expired before the CM could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pk) states.

expire(pt)

The CM registered, BPI is enabled, TEK was assigned, but the current TEK expired before the CM could successfully renew a new KEK value.

expire(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI is enabled, TEK was assigned, but the current TEK expired before the CM could successfully renew a new KEK value.

Note

This state is equivalent to the online(d) and expire(pt) states.

Error Status Conditions

reject(m)

The CM attempted to register but registration was refused due to a bad Message Integrity Check (MIC) value. This also could indicate that the shared secret in the DOCSIS configuration file does not match the value configured on the CMTS with the cable shared-secret command.

In Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later releases, this could also indicate that the cable tftp-enforce command has been used to require that a CM attempt a TFTP download of the DOCSIS configuration file before registering, but the CM did not do so.

reject(c)

The CM attempted to register, but registration was refused due to a a number of possible errors:

The CM attempted to register with a minimum guaranteed upstream bandwidth that would exceed the limits imposed by the cable upstream admission-control command.
The CM has been disabled because of a security violation.
A bad class of service (COS) value in the DOCSIS configuration file.
The CM attempted to create a new COS configuration but the CMTS is configured to not permit such changes.
The CM failed the timestamp check for its DOCSIS configuration file. (This could indicate a possible theft-of-service attempt, or a problem with the synchronization of the clocks on the CM and CMTS.)

reject(pk)

KEK key assignment is rejected, BPI encryption has not been established.

reject(pkd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because KEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pk) states.

reject(pt)

TEK key assignment is rejected, BPI encryption has not been established.

reject(ptd)

The CM registered, but network access for CPE devices using this CM has been disabled through the DOCSIS configuration file. In addition, BPI encryption was not established because TEK key assignment was rejected.

Note

This state is equivalent to the online(d) and reject(pt) states.

reject(ts)

The CM attempted to register, but registration failed because the TFTP server timestamp in the CM registration request did not match the timestamp maintained by the CMTS. This might indicate that the CM attempted to register by replaying an old DOCSIS configuration file used during a prior registration attempt.

reject(ip)

The CM attempted to register, but registration failed because the IP address in the CM request did not match the IP address that the TFTP server recorded when it sent the DOCSIS configuration file to the CM. IP spoofing could be occurring.

reject(na)

The CM attempted to register, but registration failed because the CM did not send a Registration-Acknowledgement (REG-ACK) message in reply to the Registration-Response (REG-RSP) message sent by the CMTS. A Registration-NonAcknowledgement (REG-NACK) is assumed.

⁶ The CM MAC state field can also be retrieved using SNMP by getting the value of the cdxCmtsCmStatusValue object in the CISCO-DOCS-EXT-MIB.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Table below shows the possible values for the MAC state field for a wideband-capable CM that registers as a wideband modem:

Table 56 Additional MAC States for a Wideband Cable Modem

Syntax Description

profile	(Optional) Profile number. Valid values start with 1.
verbose	(Optional) Displays detailed information for an individual profile.
iuc-code	(Optional) Internal usage code (IUC). Valid options are: a-long—Advanced Phy Long Grant Burst (IUC 10)a-short—Advanced Phy Short Grant Burst (IUC 9)a-ugs—Advanced Phy Unsolicited Grant Burst (IUC 11)initial—Initial Ranging Burst (IUC 3) long—Long Grant Burst (IUC 6) reqdata—Request/Data Burst (IUC 2) ⁷request—Request Burst (IUC 1) short—Short Grant Burst (IUC 5) station—Station Ranging Burst (IUC 4)
cable slot /port	For uBR series router, identifies a cable interface and downstream port on the Cisco uBR7100 series and Cisco uBR7200 series routers. On the Cisco uBR7100 series router, the only valid value is 1/0. On the Cisco uBR7200 series router, slot can range from 3 to 6, and port can be 0 or 1, depending on the cable interface.
cable slot /subslot /port	For uBR series router, identifies a cable interface on the Cisco uBR10012 router. The following are the valid values: slot = 5 to 8 subslot = 0 or 1 port = 0 to 4 (depending on the cable interface)
upstream port	(Optional) For uBR series router, displays information for a particular upstream on the selected cable interface. The port value starts with 0 and continues up, depending on the type of cable interface card.
cable slot /card/port	For cBR series router, identifies a cable interface on the Cisco cBR-8 router. The following are the valid values: slot = 0 to 9 card = 0 port = 0 to 15 (depending on the cable interface)
us-channel us-channel-id	(Optional) For cBR series router, displays information for a particular upstream on the selected cable interface. The us-channel-id value is from 0 to 12, depending on the type of cable interface card.
ofdma	Displays the OFDMA modulation profile details.

⁷ The Cisco CMTS recognizes the reqdata burst type but does not use it.

Command Modes

Privileged EXEC

Command History

Release	Modification
11.3 XA	This command was first introduced.
12.(0)5T1, 12.0(6)SC, 12.1(2)EC	This command was supported, replacing the show cable burst-profile command.
12.1(3a)EC	This reqdata type was added as a placeholder for scripts that might reference it, but the DOCSIS MAC scheduler on the Cisco CMTS does not use this type of burst.
12.2(15)CX	Support was added for the Cisco uBR-MC28U/X cable interface line card, including support for DOCSIS 2.0 A-TDMA and mixed modulation profiles. This includes adding additional information to the command’s display, as well as adding the a-long, a-short, a-ugs, and verbose options.
12.2(15)CX1	Added the ability to display the modulation profiles being used by a particular cable interface and upstream.
12.2(15)BC2	This command displays all default modulation profiles 1, 21, 41, 101, 121, 201, 221, and 241), even when the cable interface card that is associated with those profiles is not installed. Previous releases displayed only the default modulation profiles that were in use.
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR Series Converged Broadband Routers. The value range for the slot /card /port variables are changed.
Cisco IOS XE Everest 16.6.1	This command was modified. The ofdma keyword was added to display the OFDMA modulation profile details.

Usage Guidelines

The show cable modulation-profile command displays modulation profile group information. A modulation profile is a collection of burst profiles that are sent out in a Upstream Channel Descriptor (UCD) message to configure a modem’s transmit parameters for an upstream message burst type.

Table below shows the IUC codes for each burst type:

Table 60 Internal Usage Code Types
IUC	Type	IUC	Type
IUC 1	Request Burst (req)	IUC 7	Not used
IUC 2	Request/Data Burst (reqdata)⁸	IUC 8	Not used
IUC 3	Initial Ranging Burst (initial)	IUC 9	Advanced Phy Short Grant Burst (a-short)
IUC 4	Station Ranging Burst (station)	IUC 10	Advanaced Phy Long Grant Burst (a-long)
IUC 5	Short Grant Burst (short)	IUC 11	Advanaced Phy Unsolicited Grant Burst (a-ugs)
IUC 6	Long Grant Burst (long)	IUC 12	Not used

⁸ The Cisco CMTS recognizes the reqdata burst type but does not use it.

Modulation Profile Ranges

The ranges for modulation profiles depends on the cable interface being used and the type of modulation profile being created. Table below lists the valid ranges according to cable interface and modulation type:

Table 61 Allowable Ranges for Modulation Profiles
Cable Interface	DOCSIS 1.X (TDMA)	Mixed DOCSIS 1.X/2.0	DOCSIS 2.0 (A-TDMA)
Cisco uBR7100 series	1 to 10⁹, default=1	N/A	N/A
Cisco uBR-MC16C	1 to 10, default=1	N/A	N/A
Cisco uBR-MC16S	1 to 10, default=1	N/A	N/A
Cisco uBR-MC28C	1 to 10, default=1	N/A	N/A
Cisco uBR10-MC5X20S, Cisco uBR10-MC5X20U, Cisco uBR10-MC5X20H	21 to 30, default=21	121 to 130, default=121	221 to 230, default=221
Cisco uBR-MC16U/X, Cisco uBR-MC28U/X	41 to 50, default=41	141 to 150, default=141	241 to 250, default=241

⁹ Only 8 modulation profiles are supported in Cisco IOS software releases before 12.2(15)BC1, so in these releases the valid range is 1 to 8.

Note

Default modulation profiles are created for each type of card and operation mode. You cannot delete the default modulation profiles (1, 21, 41, 101, 121, 201, 221, and 241). In Cisco IOS Release 12.2(15)BC2 and later, all default modulation profiles are displayed, even when that particular cable interface is not installed. In previous versions, only the default modulation profiles that were in use were displayed.

Table below describes the significant fields displayed by the show cable modulation-profile command.

Table 62 show cable modulation-profile field descriptions
Field	Description
Mo	Modulation profile group number. A modulation profile group is the set of burst profiles that defines upstream transmit characteristics for the various types of upstream transmission classes.
IUC	Interval usage code. Each upstream transmit burst belongs to a class that is given a number called the interval usage code (IUC). Bandwidth maps messages (MAP) by IUC codes used to allocate upstream time slots. The following types are currently defined: Request—Bandwidth request slot Request Data—Bandwidth request and short data burst slot Initial Maintenance—Initial link registration contention slot Station Maintenance—Link keepalive slot Short Data Grant—Short data burst slot Long Data Grant—Long data burst slot
Type	Modulation type.
Preamb length	Preamble length.
Diff enco	Differential encoding enabled (yes) or not enabled (no).
FEC T bytes	Number of bytes that can be corrected for each forward error correction (FEC) code word.
FEC CW size	Size, in bytes, of the FEC code word.
Scrambl seed	Scrambler seed value in hex format.
Max B size	Maximum burst size.
Guard time size	Time between successive bursts measured in symbols.
Last CW short	Handling of FEC for shortened last code word.
Scrambl	Scrambler enabled (yes) or not enabled (no).
Preamb offset	(DOCSIS 1.0 and DOCSIS 1.1 modulation profiles) The bits to be used for the preamble value.
Pre offst	(DOCSIS 2.0 modulation profiles) The bits to be used for the preamble value.
Pre Type	(DOCSIS 2.0 modulation profiles) The A-TDMA preamble type (qpsk0 or qpsk1).
RS	(DOCSIS 2.0 modulation profiles) The A-TDMA RS encoding type.

Command History

Release	Modification
12.2(33)SCE	This command was introduced.

Usage Guidelines

The show cable multicast debug command provides information only about the explicit tracking database counter in Cisco IOS Release 12.2(33)SCE and later. This means that the command output does not include other debug counters such as multicast authorization and multicast quality of service (QoS).

If you want to verify multicast group specific or MAC specific debug counters, you must turn on debugging of multicast counters using the debug cable multicast counter start command before using the show cable multicast debug command.

Note

The command output will be the same if you run the show cable multicast debug command with or without the keyword etdb in Cisco IOS Release 12.2(33)SCE, because this command does not support any other debug counters in Cisco IOS Release 12.2(33)SCE.

Examples

The following is a sample output of the show cable multicast debug command that displays information about multicast explicit tracking database debug counters on the Cisco uBR10012 router:

Router# show cable multicast debug

Profiles 1 and 2 are always created by the CMTS at initial startup. The CMTS dynamically creates profiles 3 and 4, as shown above, to support Voice over IP (VoIP) codecs G.711 and G.729 when a CM configures phone lines and uses dynamic service requests to request VoIP service. The remaining profiles, such as profile 5 above, are typically created by a CM when it comes online.

Profile 3 creates a grant-size of 31.22 KiloBytes per second for G.729 service, and profile 4 creates a grant-size of 87.2 KiloBytes per second for G.711 service. Both profiles use a default grant-interval of 20 milliseconds. For more information on these profiles, see the TAC technical note at the following URL: http://www.cisco.com/warp/public/109/uBR7200_QoSMAC.html

The following example displays detailed output for profile 1:

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Related Commands

Command	Description
cable service class	Defines and modifies a service class.
show interface cable qos paramset	Displays the parameters in one or more service templates.

show cable service-voice downstream-type

To display the downstream-types that are capable of providing voice services, use the show cable service-voice downstream-type command.

show cable service-voice downstream-type

Syntax Description

This command has no keywords or arguments.

Command Default

None

Command Modes

Privileged EXEC

Command History

Release	Modification
12.3(23)BC	This command was introduced for the Cisco uBR10012 router.
IOS-XE 3.15.0S	This command is not supported on the Cisco cBR Series Converged Broadband Routers.

Usage Guidelines

Use this command to display the downstream-types that are capable for providing voice services on each uBR10-MC 5x20 line card.

Examples

The example below shows that both HA-capable-DS and MDC-DS are enabled for downstream types on the uBR10-MC5X20 line card in slot 5, subslot 1 and the line card in slot 6, subslot 0.

Router# show cable service-voice downstream-type
Slot 5/1 :    HA-capable-DS               MDC-DS
Slot 6/0 :    HA-capable-DS               MDC-DS

show cable service-flow summary

To display system level service flow and downstream classifier summary information per line card basis, use the show cable service-flow summary command in privileged EXEC mode..

show cable service-flow summary

Syntax Description

This command has no keywords or arguments.

Command Default

None

Command Modes

Privileged EXEC mode

Command History

Release	Modification
12.2(33)SCJ	This command was introduced.
IOS-XE 3.18.0S	This command was implemented on the Cisco cBR Series Converged Broadband Routers.

Usage Guidelines

The show cable service-flow summary command displays system level service flow and downstream classifier summary information per line card basis. For uBR10K series routers, system level downstream classifier resource used percentage and downstream service flow system limit are displayed. However, for cBR Series Converged Broadband Routers, the downstream classifier used percentage and system limit are not displayed. This command displays only the unicast service flow summary information and limit and excludes multicast service flows.

For uBR10k series routers:

Downstream service flow:

For a given MC2020, MC3G60, 3GSPA or 6GSPA Line Card, per Line Card limit is about 64k. However, the upper limit per line card is highly dependent on configuration. For example, the downstream service flow limit would differ if two MC3G60 Line Cards share the same 3GSPA. So it is not possible to set a fixed value for Line Card downstream service flow upper limit.

For each chassis limit the fixed value is 294865. This is similar to a “RP flow” table resource.

Note

Each downstream service flow and downstream classifier consumes one “RP flow” table resource. So actual limit depends on the downstream service flow and classifier configuration.

Upstream service flow

Limited by 8K SID space per mac-domain.

Note

If SID Cluster is configured, one upstream service flow might have multiple SIDs and the total upstream service flow limit per mac-domain will be lesser than 8K.

64K per line card.
There is no chassis limit on the CMTS. In order to specify this, the command output displays "Not Applicable".

Dowstream classifier
- Each chassis is limited by "RP flow" table resource.
- The fixed limit is displayed in percentage.
Upstream classifier
- The upstream classifier has no limit on CMTS and it is not displayed on the output.

For cBR Series Converged Broadband Routers, the following limitations are applicable:

Downstream service flow
- The downstream service flow count is limited by Yoda capability even though hardware limitation per CLC is 128K. Each Yoda has a limitation about 100K+ service flows and the Yoda to CLC mapping decides the CLC limitation. For example, if Yoda 1 is mapped to CLC1 and CLC2, the two CLCs has a shared limitation of 100K service flows. However, if Yoda 1 is mapped only to CLC1, CLC1 alone could reach 100K service flows.
- 426K per chassis for Quad Yoda. 72K per chassis for one Yoda.
- The downstream service flow upper limit is not displayed since it is not possible to derive a fixed value.

Upstream service flow

Similar to uBR10K Series Routers, the upstream service flow is limited by 8K SID space per mac-domain.

Note

If SID Cluster is configured, one upstream service flow might have multiple SIDs and the total upstream service flow limit per mac-domain will be lesser than 8K.

No chassis limit on CMTS.

Downstream classifier
- No limit on CMTS.
- There is no "RP flow" table resource for cBR Series Converged Broadband Routers and no used percentage is displayed on the output.
Upstream classifier

Cisco uBR Series Router

show cable signal-quality { cable { slot /port | slot /subslot /port } upstream number | cmts | mer }

show cable signal-quality { cable slot /card /port upstream number | cmts | mer }

Syntax Description

cable	Specifies the cable interface.
slot /subslot /port	For uBR series router, displays information about all CMs on the specified cable interface line card on a Cisco CMTS router: slot —Chassis slot number of the cable interface line card. Valid slots are from 5 to 8. subslot —Secondary slot number of the cable interface line card. Valid subslots are 0 or 1. port —Port number. Valid ports are from 0 to 4, depending on the cable interface line card.
slot /card /port	For cBR series router, displays information about all CMs on the specified cable interface line card on a Cisco CMTS router: slot —Chassis slot number of the cable interface line card. Valid slots are 0 to 9. card —Secondary slot number of the cable interface line card. Valid subslots is 0. port — Cable interface index. Valid ports are from 0 to 15, depending on the cable interface line card.
upstream number	Specifies the upstream channel ID. Valid values are from 0 to 3.
cmts	Displays the carrier-to-noise ratio (CNR) data and expected signal power received per cable interface.
mer	Displays the modulation error rate (MER) data per cable interface.

Command Modes

Privileged EXEC (#)

Command History

Release	Modification
12.2(33)SCC	This command was introduced in Cisco IOS Release 12.2(33)SCC.
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR Series Converged Broadband Routers. The value range for the slot /card /port variables are changed.

Usage Guidelines

The show cable signal-quality command with the mer keyword displays the modulation error rate data per cable interface. Note that at least one cable modem (CM) must be online on the cable interface for this command to provide the modulation error rate data. This is identical to the modulation error rate data displayed by the show controllers command.

The CNR data is displayed only for the upstream channels that are assigned to a spectrum group. Upstream channels with fixed frequencies do not return any CNR data.

Examples

Table below describes the fields shown in the show cable spectrum-group displays.

Table 94 show cable spectrum-group Command Field Descriptions
Field	Description
Group No.	Identifies the spectrum group. When using the detail keyword, the following also appear: A = Signifies that the band is allocated. F = Signifies that the band is free. I = Signifies that the band is in-use. C = Identifies the channel width. O = Identifies the offered list bands (based on the current channel widths).
Frequency Band (MHz)	Identifies the upper and lower ranges of the frequency for this spectrum group.
Upstream Port	Identifies the upstream port number.
Weekly Scheduled Availability	Identifies the day and time of day when this group is available. If no values appear in the From and To Time fields, this group is available at all times.
Power Level (dBmV)	Identifies the assigned decibels per millivolt (dBmV) input level.
Shared Spectrum	Indicates if upstreams are physically combined (share the same combiner group). Y or yes values indicate that upstreams that are members of the spectrum group are combined and cannot be assigned overlapping frequency bands. N or no values indicate that upstreams that are members of the spectrum group are not combined and can be assigned overlapping frequency bands.

Tip

In Cisco IOS Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a timestamp to show commands using the exec prompt timestamp command in line configuration mode.

Related Commands

Command	Description
show cable hop	Displays CM configuration settings.
show cable modulation-profile	Displays modulation profile group information.

show cable subscriber-usage

To display subscribers who are violating their registered quality of service (QoS) profiles, use the show cable subscriber-usage command in privileged EXEC mode.

show cable subscriber-usage [over-consume] [ { cable slot /port | cable slot /subslot /port } ] [ upstream port ] [ sort-byte-count ] [ sort-avg-rate ]

Syntax Description

over-consume	(Optional) Displays only those subscribers who have exceeded their maximum allowed bandwidth.
cable slot /port	(Optional) Displays information for all CMs on the specified cable interface and downstream port on a Cisco 7100 series or Cisco 7200 series router, where: slot—Specifies the chassis slot number of the cable interface line card. port—Specifies the downstream port number. Valid values for these arguments are dependent on your CMTS router and cable interface line card. Refer to the hardware documentation for your router chassis and cable interface line card for supported slot and port numbering.
cable slot/subslot/port	(Optional) Displays information for all CMs on the specified cable interface on a Cisco uBR10012 router, where: slot —Specifies the chassis slot number of the cable interface line card. Valid slots are 5 to 8. subslot —Specifies the secondary slot number of the cable interface line card. Valid subslots are 0 or 1. port —Specifies the downstream port number. Valid ports are 0 to 4, depending on the cable interface line card.
upstream port	(Optional) Displays information for a particular upstream on the selected cable interface. The port value starts with 0 and continues up, depending on the type of cable interface card.
sort-byte-count	(Optional) Sorts the list by the subscriber byte count, with the highest byte counts listed first. The default is to sort the list by Service Flow ID (SFID). (This option is replaced by the sort-avg-rate keyword in later releases.)
sort-avg-rate	(Optional) Sorts the list by the subscriber’s average rate. The default is to sort the list by Service Flow ID (SFID).

Command Default

All subscribers are shown, with the display sorted by SFID.

Command Modes

Table below describes the fields shown by the show cable subscriber-usage command.

Table 95 show cable subscriber-usage Field Descriptions

Field

Description

SFID

Number of the Service Flow ID.

Mac Address

Hardware address (MAC address) of the subscriber’s cable modem.

Enforce-rule Name

Name of the enforce-rule being applied to this subscriber.

Total-Kbyte

Total number of kilobytes consumed by the subscriber’s cable modem during the last monitoring-duration window.

Note

The total byte count is reset to 0 whenever an enforce-rule’s configuration is changed.

Note

Effective with Cisco IOS Release 12.2(33)SCA, the field Total-Kbyte has been modified to Mon-Dur Cons (kbits/sec).

Last-detect time

Last time period, if any, at which it was determined that the cable modem was using more bandwidth than allowed by their QoS profile. This value also shows the time at which the enforced QoS profile was automatically applied, if this option has been enabled.

Last-penalty time

If an enforced QoS profile is currently in effect, this field shows the time period at which the subscriber’s current penalty time expires, at which point their original registered QoS profile is restored.

Pen Flag

Identifies whether a penalty enforce-rule has been applied to this cable modem.

Related Commands

Command	Description
activate-rule at-byte-count	Specifies the number of bytes that a subscriber can transmit during the monitoring period on a Cisco CMTS router.
cable qos enforce-rule	Creates an enforce-rule to enforce a particular QoS profile for subscriber traffic management and enters enforce-rule configuration mode.
duration	Specifies the time period and sample rate to be used for monitoring subscribers.
enabled (enforce-rule)	Activates an enforce-rule and begins subscriber traffic management on a Cisco CMTS Router.
penalty-period	Specifies the time period that an enforced QoS profile should be in effect for subscribers who violate their registered QoS profiles.
qos-profile enforced	Specifies a QoS profile that should be enforced when users violate their registered QoS profiles.
qos-profile registered	Specifies the registered QoS profile that should be used for this enforce-rule.
show cable qos enforce-rule	Displays the QoS enforce-rules that are currently defined.

show cable tech-support

To display general information about the router when reporting a problem, use the show cable tech-support command in privileged EXEC mode.

show cable tech-support { slot /port | slot /subslot /port }

Syntax Description

slot /port

(Optional) Cisco IOS Release 12.3(9a)BC allows you to display information about one specific cable interface.

Identifies the cable interface and downstream port on the Cisco uBR7100 series and Cisco uBR7200 series routers.

On the Cisco uBR7100 series router, the only valid value is 1/0. On the Cisco uBR7200 series router, slot can range from 3 to 6, and port can be 0 or 1, depending on the cable interface.

slot /subslot /port

(Optional) Cisco IOS Release 12.3(9a)BC allows you to display information about one specific cable interface.

Identifies the cable interface on the router. The following are the valid values:

slot = 5 to 8 for uBR series router, 0 to 9 for cBR series router.
subslot = 0 or 1 for uBR series router, 0 for cBR series router.
port = 0 to 4 for uBR series router, 0 to 7 for cBR series router (depending on the cable interface).

Command Default

None.

Command Modes

Privileged EXEC

Command History

Release	Modification
11.2	This command was introduced.
12.1(1a)T1	This command was modified to include information about the cable clock card.
12.2(15)BC2	This command added several show pxf commands to the display on the Cisco uBR10012 router.
12.3(9a)BC	The output of the command was significantly shortened by moving a number of show commands (the ones that display information about individual cable modems) to the show tech-support command. This release also adds support for an option to display information about only one specific cable interface.
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR Series Converged Broadband Routers. The value range for the slot /subslot /port variables were changed.

Usage Guidelines

The show cable tech-support command displays a large amount of configuration, run-time status, and other information about the cable interfaces on the Cisco CMTS. The output of this command can be provided to technical support representatives when reporting a problem.

Note

The show tech-support includes most of the information shown in the show cable tech-support command. Unless the problem is clearly cable-specific, TAC personnel will typically request the show tech-support output to troubleshoot any problems.

The show cable tech-support command displays the output of a number of different show commands. The exact output depends on the platform, configuration, and type of protocols being used. The output includes the output from the following commands:

show cable modem
show cable flap-list
show cable qos profile
show cable modulation-profile
show cable spectrum-group
show cable hop
show interface cable sid (for each cable interface)
show interface cable sid connectivity (for each cable interface)
show interface cable downstream
show interface cable upstream
show interface cable mac-scheduler
show interface cable modem

Other commands could be included in the show cable tech-support output, depending on the CMTS platform, the Cisco IOS software being used, and the cards that are installed in the chassis.

On the Cisco uBR10012 router, the following commands also appear in Cisco IOS Release 12.2(15)BC2 and later releases:

show pxf cpu statistics
show pxf cpu subblocks
show pxf cpu buffer
show pxf dma
show pxf cpu cef memory
show pxf cpu queue
show pxf cpu statistics drop
show cable modem partial-mode

Tip

Depending on the platform and configuration, the output from the show cable tech-support command can easily exceed the buffers found in most communications programs. To capture this output so it can be sent to Cisco TAC, use a Telnet program that allows you to capture the output directly to disk.

Examples

The following abbreviated example illustrates the cable modem and interface information for the Cisco uBR10012 router on which Cisco IOS Release 12.3(9a)BC is installed.

cnnrs	The connector index range of connectors in a connector group. The values for the Cisco uBR-MC3GX60V, Cisco UBR-MC20X20V, and the Cisco uBR10-MC5X20U line cards are 0-19.
md:us=>cnnr	The MAC domain upstream channel to connector mapping information of a physical upstream channel. The entry position corresponding to a physical upstream channel index in a connector group. For uBR-MC3GX60V line card, there are 12 physical upstream channels in each connector group. For the UBR-MC20X20V and uBR10-MC5X20U line cards, there are 2 channels in each group. In the example, C6/1/3:U2 is mapped to connector 1 in the running config by the user using connector command. Internally, CMTS software maps C6/1/3:U2 to physical upstream channel 0 (1st entry) in the 0-3 connector group.
