Command History
12.3(23)BC
This command was introduced.
12.2(33)SCA
This command is integrated in Cisco IOS Release 12.2(33)SCA.
Usage Guidelines
The show cable mac-domain cable forwarding command does not support wideband and modular interfaces. However, if wideband and modular interfaces belong to the Mac domain, the interfaces are listed in the output with the interface state.
Starting with Cisco IOS Release 12.2(33)SCF, for a chassis loaded with the UBR-MC20X20V or uBR-MC3GX60V line cards, and legacy uBR-MC5X20 line cards, the show cable mac-domain cable forwarding command shall not display the legacy downstream information for the UBR-MC20X20V and the uBR-MC3GX60V line cards.
Examples
The following is sample output of the show cable mac-domain cable forwarding command on the cable interface at 8/0/0:

Command History
12.3(23)BC
This command was introduced for the Cisco uBR10012 router.
12.2(33)SCB
This command was integrated into Cisco IOS Release 12.2(33)SCB.
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.
•
If the All column in the command output indicates Y, then this indicates that all upstream channels associated with the line card downtream 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 display.
•
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

Privileged EXEC (#)
Command History
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.

This table includes the following release-specific history entries:
12.2(15)BC1
Additional lines were added to the show cable modem verbose displays, for one or all cable modems, to show information about the dynamic shared-secret feature. Cable modems that fail the dynamic secret authentication checks and then come online are marked with an exclamation point (!), so that this situation can be investigated.
12.2(4)BC1
Support was added for the Cisco uBR10012 router.
12.2(8)BC2
The output for the Online State field was updated for the cable tftp-enforce command. A pound sign (#) appears next to the state value when a CM was allowed to come online without attempting to download a DOCSIS configuration file through the cable interface with 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 abortedIf 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.

Table 23 shows the possible values for the MAC state field:
Table 6 Descriptions for the MAC State Field 1
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
assign(epk)
BPI is enabled and KEK is assigned.
assign(ept)
BPI is enabled and TEK is assigned. The registration messages will be encrypted.
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
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.
If early authentication and encryption is used, the letter `s' is appended to these states to indicate secure registration.
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.
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).
resetting
The CM is being reset and will shortly restart the ranging and registration process.
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
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
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
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
expire(epk)
Early authentication and encryption 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
expire(ept)
Early authentication and encryption 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
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:
•
•
•
•
•
reject(epk)
Early authentication and encryption is enabled, KEK key assignment is rejected, and the modem has not been authenticated.
reject(pk)
KEK key assignment is rejected, and the modem has not been authenticated.
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
reject(ept)
Early authentication and encryption is enabled, TEK key assignment is rejected, and 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
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.
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.

show cable modem cnr
To display information about the upstream carrier-to-noise ratio (CNR) or signal-to-noise ratio (SNR) for a particular cable modem (CM), use the show cable modem command in privileged EXEC mode.
show cable modem {ip-address | mac-address | name fqdn} cnr
Syntax Description
Command Modes
Privileged EXEC (#)
Command History
This table includes the following release-specific history entries:
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:
•
•
•
•
•
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 abortedIf this occurs, wait a minute or so and retry the command.

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
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
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.
init6(s)
Cisco CMTS router learns the DHCPv6 SOLICIT message from the CM.
init6(a)

init6(t)
Cisco CMTS router learns the REQUEST message from the CM to the ToD server.
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
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

Note
Note
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
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
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:
•
•
•
•
•
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
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
Note
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.

This command displays packet header error information for all CMs, for all CMs attached to a specific CMTS cable interface, or for a particular CM, as identified by its IP address or MAC address.
Note
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 abortedIf this occurs, wait a minute or so and retry the command.

IP Address
IP address acquired by the CM. Prior to acquisition of the IP address, or if the CM fails registration, the following output is shown:
•
•
•
•
Domain Name
Domain name for the CM.
Table 23 shows the possible values for the MAC state field:
Table 23 Descriptions for the MAC State Field 1
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
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
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.
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.
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
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
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
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
Note
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
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
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:
•
•
•
•
•
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
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
Note
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.
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.

Note
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 abortedIf this occurs, wait a minute or so and retry the command.
Tip
Cisco IOS Release 12.3(17a)BC introduces changes for two versions of the show cable modem mac command.
•
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 23 shows the possible values for the MAC state field:
Table 25 Descriptions for the MAC State Field 1
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
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
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.
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.
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
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

Note
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
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:
•
•
•
•
•
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
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
Note
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.
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.

The Cisco CMTS router has seen the REQUEST message from the CM to the TOD server.
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
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
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
online(pk)
The CM registered, BPI is enabled and KEK is assigned.

Note
Note
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
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
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:
•
•
•
•
•
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
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
Note
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.
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.

Privileged EXEC (#)
Command History
Usage Guidelines
If all cable modems are in full service mode (all downstream and upstream channels of the cable modems are online and operational), then the show cable modem partial-mode command does not provide any output. This command provides output only when the cable modems register in partial service mode (one or more downstream or upstream channels of the downstream or upstream bonded cable modems are not operational).
Examples
The following is a sample output of the show cable modem partial-mode command that displays all the cable modems in partial service mode:

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

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 form displays complete information for each flow.
Note
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 abortedIf this occurs, wait a minute or so and retry the command.

Table 0-35 Descriptions for the show cable modem remote-query Fields
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
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
Modem State
The current state of the MAC layer for the CM (see Table 23).

Command History
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 abortedIf this occurs, wait a minute or so and retry the command.

Note
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
ticks = microseconds*64/6.25.Table 42 describes the major fields shown in the show cable modem unregistered displays:
Table 42 Descriptions for the show cable modem unregistered Fields
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 (see Table 23).
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
Note
Rec Power
The received power level (in dB) for the CM.
Note
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.
Table 23 shows the possible values for the Online State field:
Table 43 Descriptions for the Online State Field 1
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
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
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.
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.
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
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
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
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
Note
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
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
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:
•
•
•
•
•
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
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
Note
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.
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.

Table 45 Descriptions for the show cable modem wideband Fields
MAC Address
MAC address for the CM.
IP Address
IP address that the DHCP server has assigned to the CM.
I/F
Cable interface providing the upstream for this CM.
MAC State
The current state of the MAC layer (see Table 46).
Prim SID
Primary SID assigned to this CM.
Bonding group ID
Identifier of the primary wideband channel.
DSID
Downstream Service Identifier.
DSxUS
Number of DS and US channels used by the CM.
Primary WB
Primary wideband channel for the CM.
MD-DS-SG
MAC Domain Downstream Service Group, the downstream channels of a single MAC domain that reach the cable modem.
Table 46 shows the possible values for the MAC State field for a wideband CM modem that registers as a traditional DOCSIS modem:
Table 46 Descriptions for the MAC State Field (for Traditional DOCSIS Modems) 1
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
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
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.
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
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
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
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
Note
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
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
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:
•
•
•
•
•
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
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
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.
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.

Command Modes
Privileged EXEC (#)
Command History
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
The following example shows the CNR data received on the upstream ports on the cable interface line card at slot/subslot/port 7/0/3 on a Cisco uBR10012 router:
