Table 0-38 describes the significant fields shown in the display.

Table 0-38 show bridge cable-modem Field Descriptions

Field
Description

Total of 300 station blocks

Total number of forwarding database elements in the system. The memory to hold bridge entries is allocated in blocks of memory sufficient to hold 300 individual entries. When the number of free entries falls below 25, another block of memory sufficient to hold another 300 entries is allocated. Thus, the total number of forwarding elements in the system is expanded dynamically, as needed, limited by the amount of free memory in the router.

Bridge Group

The number of the bridge group to which this interface is assigned.



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

Table 42 describes the significant fields for the show cable admission-control command for upstream and downstream throughput.

Table 42 show cable admission-control Field Descriptions 

Field
Description

Bucket No

Specific bucket number.

Names

Bucket name.

Minor Level

Minor threshold as currently defined in a percentage on the Cisco CMTS.

# of Times

Number of times traffic has crossed this threshold since the counters on the Cisco CMTS were last cleared.

Major Level

Major threshold as currently defined in a percentage on the Cisco CMTS.

Excls Level

Percentage of exclusive throughput that is reserved for the corresponding traffic type on the Cisco CMTS. Applies to downstream or upstream traffic.

Non-Ex Level

Percentage of non-exclusive throughput configured on the Cisco CMTS. Commonly used with Best Effort (lowest priority) traffic.

Curr Resv

Percentage of throughput reserved exclusively for the corresponding flow type.

Conf Level

Configuration level that indicates the scope of configuration is actually applied for that US/ DS (whether the global, interface, or the upstream level is applied). The values in this field can be as follows:

U—Upstream

I—Interface

G—Global

# of Rejec

Number of rejections.

Sched Type

Available for upstream only. This field displays the following information:

UGS—UGS thresholds configured and traffic rates.

RTPS—RTPS thresholds configured and traffic rates.

BE—Best Effort thresholds configured and traffic rates.

Flow Type

Available for Downstream only. This field displays voice and data information:

voice—Voice thresholds configured and traffic rates.

data—Data thresholds configured and traffic rates.

Class Name

Available for upstream only.

CM-Registration event

Counter increments once for every cable modem that crosses a threshold during its registration. For example, if the minor, major, and critical thresholds on the Cisco CMTS are 60%, 70%, and 80% respectively, and a cable modem tries to register when the current value is 80%, then the cable modem is allowed to register, but the counters for minor, major and critical thresholds are each incremented by one.

Voice-Call event

Counter increments if the resource check fails when a voice-call is made. For example, assume both the MTAs are on the same Cisco CMTS, and minor, major, and critical thresholds for I/O memory are 50%, 60%, and 70%, respectively. Then assume the current I/O memory value is 75%. In this scenario, before the gate creation, AC performs an I/O memory check. This results in the counters for minor, major, and critical thresholds each being incremented by one, and the voice call fails. No packetcable gates are created because the voice calls fail.

show cable arp-filter

To display the total number of Address Resolution Protocol (ARP) replies and requests that have been sent and received, including the number of requests that have been filtered, use the show cable arp-filter command in privileged EXEC mode.

show cable arp-filter cable slot/port [ip-requests-filtered number] [requests-filtered number | replies-filtered number]

show cable arp-filter cable slot/subslot/port [ip-requests-filtered number] [requests-filtered number | replies-filtered number]

Syntax Description

cable slot/port

Displays information for all CMs on the specified cable interface and downstream port on the Cisco uBR7246VXR router.

On the Cisco uBR7246VXR router, slot can range from 3 to 6, and port can be 0 or 1, depending on the cable interface.

cable slot/subslot/port

Displays information for all CMs on the specified 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)

[ip-requests-filtered number]

(Optional) Displays the Service IDs (SIDs) that are generating or forwarding more filtered ARP requests for IP packets than the specified minimum number of packets. The valid range for number is 1 to 65535, with no default.

Note This field shows the modems that are forwarding IP traffic that could be an part of an attack, such as TCP SYN floods, ping scans, and so forth.

[requests-filtered number]

(Optional) Displays the Service IDs (SIDs) that are generating or forwarding more filtered ARP requests than the specified minimum number of packets. The valid range for number is 1 to 65535, with no default.

[replies-filtered number]

(Optional) Displays the Service IDs (SIDs) that are generating or filtering more filtered ARP replies than the specified minimum number of packets. The valid range for number is 1 to 65535, with no default.

Modification

12.2(15)BC2

This command was introduced for the Cisco uBR7246VXR and Cisco uBR10012 universal broadband routers.

12.2(15)BC2b

The ip-requests-filtered option was added to display the specific Service IDs (SIDs) that are generating or forwarding a minimum number of ARP packets.


Usage Guidelines

The cable arp filter command enables the filtering of ARP request and reply packets on a cable interface. ARP packets might need to be filtered when a user on the cable network generates a large volume of ARP traffic as part of a theft-of-service or denial-of-service attack, or when a virus is using ARP requests to find other computers that it might infect.

The show cable arp-filter command displays the total number of ARP reply packets that have been received and the number of ARP request packets that have been sent on the cable interface, as well as the number of such packets that have been filtered.


Tip To clear the counters on all interfaces, use the clear counters command. To clear the counters on a specific interface, use the clear counters cable interface command.


Examples

The following example shows the typical output from the show cable arp-filter command on a Cisco uBR10012 router. The displays for other Cisco CMTS platforms are similar.

Table 0-43 describes the fields shown in the display.

Table 0-43 show cable arp-filter Field Descriptions 

Field
Description
Replies Rcvd

Total

Total number of ARP reply packets received on the cable interface since power-on.

Unfiltered

Number of ARP reply packets that the cable interface received and accepted while filtering was enabled using the cable arp filter reply-accept command.

Filtered

Number of ARP reply packets that the cable interface dropped while filtering was enabled, because they would have otherwise exceeded the allowable threshold value that was configured for the interface using the cable arp filter reply-accept command.

Requests Sent For IP

Total

Total number of ARP request packets that the cable interface was asked to forward since power-on.

Unfiltered

Number of ARP request packets that the cable interface sent while filtering was enabled using the cable arp filter request-send command.

Filtered

Number of ARP request packets that the cable interface dropped, because they would have otherwise exceeded the allowable threshold value that was configured for the interface using the cable arp filter request-send command.

Requests Forwarded

Total

Total number of ARP request packets that the cable interface was asked to forward to the ARP proxy since power-on.

Unfiltered

Number of ARP request packets that the cable interface sent to the ARP proxy while filtering was enabled using the cable arp filter request-send command.

Filtered

Number of ARP request packets for the ARP proxy that the cable interface dropped, because they would have otherwise exceeded the allowable threshold value that was configured for the interface using the cable arp filter request-send command.

Note All counters are 16-bit counters, with a maximum value of 65,535 packets. If the number of packets exceeds this amount, the counter wraps back to zero and begins incrementing again.



Note The Total counts in the show cable arp-filter command continue to increment, regardless of whether ARP filtering has been enabled. The Unfiltered and Filtered counts increment only when ARP filtering has been enabled using the cable arp filter command. When cable ARP filtering is disabled, these counters retain their current values until manually reset, using the clear counters command.

Table 0-44 describes the fields shown in the display.

Table 0-44 show cable arp-filter Detail Field Descriptions 

Field
Description

SID

Service ID (SID) of the device.

MAC Address

Hardware (MAC-layer) address of the cable modem or CPE device.

IP Address

IP address of the cable modem or CPE device.

Req-Filtered

Total number of ARP requests that the device has generated or forwarded.

Req-For-IP-Filtered

Total number of ARP requests that the device has generated or forwarded for IP packets.

Rep-Filtered

Total number of ARP replies that the device has generated or forwarded.

Note The Req-Filter and Rep-Filtered counters are 16-bit counters, with a maximum value of 65,535 packets. If the number of packets exceeds this amount, the counter wraps back to zero and begins incrementing again.


Clearing the ARP Packet Counters

The following example shows the cable ARP counters being cleared by the clear counters cable interface command. This can be useful because the ARP counters are 16-bit counters that can wrap around to zero relatively quickly when large amounts of ARP traffic is being generated. Also, the ARP packet counters could include SIDs that had forwarded large amounts of ARP traffic in the past, but that are not currently forwarding such traffic. Clearing the counters allows you to clearly see the SIDS that are currently forwarding the ARP traffic that is triggering the ARP filters.

12.0(7)XR2

This command was introduced.

12.0(8) SC

This command was supported.

12.1(2) EC1

This command was supported.

12.2(4)BC1

Support was added to the Release 12.2 BC train.

12.1(13)EC, 12.2(11)BC1

The Flags, Location, link, and sublink fields were added to the display to aid in debugging.

12.3(21)BC

All cable bundles are now automatically converted and configured to be in a virtual bundle, and standalone cable interfaces must be manually configured to be in a virtual bundle to operate properly. Previously, new virtual interface bundles and bundle members required reconfiguration, and there could also be standalone interfaces not part of a bundle at all.


Usage Guidelines

Beginning with Cisco IOS Release 12.3(21)BC, all cable bundles are automatically converted and configured to be in a virtual bundle after loading the software image.

In releases prior to Cisco IOS Release 12.3(21)BC, if you delete the virtual bundle interface, the virtual bundle disappears.

Beginning with Cisco IOS Release 12.3(21)BC, standalone cable interfaces must be manually configured to be in a virtual bundle to operate properly.

The virtual bundle interface accumulates the counters from members; counters on member links are not cleared when they are added to the bundle. If a bundle-only counter is desired, clear the bundle counter on the members before adding them to the bundle, or before loading the image (for Cisco IOS Release 12.3(21)BC and later).

show cable bundle bundle# multicast [ MAC addr | IP addr ]

Syntax Description

bundle#

The alphanumeric identifier for the virtual interface bundle.

group

Multicast group membership identifier.

MAC addr

Optional parameter specifies the MAC address for which to return information.

IP addr

Optional parameter specifies the IP address for which to return information.


Command Modes

User EXEC or Privileged EXEC

Command History

Release
Modification

12.3(21)BC

This command was introduced to support virtual interface bundling on the Cisco CMTS. All cable bundles are now automatically converted and configured to be in a virtual bundle, and standalone cable interfaces must be manually configured to be in a virtual bundle to operate properly. Previously, new virtual interface bundles and bundle members required reconfiguration, and there could also be standalone interfaces not part of a bundle at all.


Usage Guidelines

Beginning with Cisco IOS Release 12.3(21)BC, all cable bundles are automatically converted and configured to be in a virtual bundle after loading the software image.

In releases prior to Cisco IOS Release 12.3(21)BC, if you delete the virtual bundle interface, the virtual bundle disappears.

Beginning with Cisco IOS Release 12.3(21)BC, standalone cable interfaces must be manually configured to be in a virtual bundle to operate properly.

The virtual bundle interface accumulates the counters from members; counters on member links are not cleared when they are added to the bundle. If a bundle-only counter is desired, clear the bundle counter on the members before adding them to the bundle, or before loading the image (for Cisco IOS Release 12.3(21)BC and later).

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

Examples

The following example illustrates this new command. This command translates the bundle's multicast MAC address to Multicast IP address information, including the associated multicast source.

Router# show cable bundle bundle1.1 multicast
CableBundle  Interface   Source IP        Multicast IP     MAC Address
1            Bundle1.1   *                230.1.1.1        0100.5e00.0001

The following example illustrates multicast information for the specified virtual bundle:

Router# sh cable bundle 1 multicast 
CableBundle  Interface   Source IP        Multicast IP     MAC Address
1            Bundle1     *                239.0.0.100      0100.5e00.0001

To translate a MAC address back to Multicast IP address, use the following optional syntax:

show cable bundle bundle# multicast [ <MAC addr | IP addr >]

The following example illustrates this enhanced show command:

Router# show cable bundle bundleID multicast 0100.5e00.0001
MAC address       Interface    Flags Location   link     sublink
0100.5e00.0001    Bundle1        1   646FE4D8   0        646FE4EC

A Cisco uBR7246 VXR router using a Cisco uBR-MC16S, Cisco uBR-MC16E, Cisco uBR-MC28C, or Cisco uBR-MC28C-BNC cable interface line card. The router must also be equipped with a Cisco cable clock card and be running Cisco IOS 12.1(1a)T1, 12.1(2)EC1, or a later release. The Cisco cable clock card should be connected to an external national clock source.

Only these cable interface cards support the external clock card reference from a clock card to distribute that signal to CMs or set-top boxes (STBs) attached to the specific network segments. You can use other cable interface cards, such as the Cisco uBR-MC16C, with the clock card, but these other cable interfaces will not synchronize their downstream SYNC messages with the external clock source.

Each CM or STB must also support VoIP applications and the clock feature set. For example, the Cisco uBR924, running Cisco IOS Release 12.0(7)T or later, supports clock card feature automatically.


Note This command does not appear if a clock card is not installed in the system.


Examples

The following sample output from the show cable clock command on a Cisco uBR7246VXR router shows that both external sources are available and the clock card is providing the clock reference:

Router# show cable clock 
Clockcard primary input is present
Clockcard secondary input is present
Cable clock reference is clockcard primary input
Cable3/0 Timestamp clock reference is from Clockcard 
Cable4/0 Timestamp clock reference is from Clockcard 

The following sample output from the show cable clock command on a Cisco uBR10012 router shows that both external sources are available and that the TCC+ card in slot 1/1 is providing the clock reference:

Table 52 describes the major fields shown in the show cable dsg command:

Table 52 show cable dsg Field Descriptions 

Field
Description

DSG keepalive is set

If keepalive messages have been enabled for an IP multicast group, using the cable dsg keepalive command, this message is displayed.

Dest-ip, Group address

Multicast group IP address for the DSG stream.

Src-ip, Source address

Source IP address for the DSG stream. If an asterisk (*) appears as the source IP address, it indicates that the source IP address is 0.0.0.0, which allows any IP address as the source IP address.

Mapped-MAC, Tunnel-MAC

Well-known MAC address used for the DSG tunnel. If you configured the DSG tunnel with a MAC address of 0000.0000.0000 using the cable dsg command, this field shows the MAC address that the CMTS derived using the MAC to IP multicast addressing mapping that is specified in RFC 1112.

Interface

Cable interface on which this DSG tunnel is configured.

mapping entry is used

Number of times that this particular DSG tunnel mapping has been used to resolve the well-known MAC address from the tunnel's group address. This can be used as a very rough approximation of the number set-top boxes (STBs) that have been mapped to this DSG tunnel since the last time the counter was cleared.

Note Use the clear cable dsg command to clear this counter.

Packets

Number of packets transmitted over the DSG tunnel.

CA-vendor

Name for the Conditional Access (CA) vendor that owns this tunnel.

Received

Number of packets received by the multicast group. This counter includes all interfaces that are receiving traffic for the multicast group. The field is not shown when an interface is shut down, but the counter continues to increase as long as the multicast group is receiving traffic. When the interface is reenabled, the counter shows the latest number of packets received.

Forwarded

Number of packets forwarded on the cable interface for the multicast group. This counter is reset to 0 whenever an interface is shut down and reenabled. The field is not shown when an interface is shut down.

Dropped

Number of packets that were dropped that were for the multicast group. This counter includes all interfaces that are receiving traffic for the multicast group. The field is not shown when an interface is shut down, but the counter continues to increase as long as the multicast group is receiving traffic and dropping packets. When the interface is reenabled, the counter shows the latest number of packets dropped.



Note The Received and Dropped counters reflect activity for the multicast group and are not affected when a cable interface is shut down and reenabled, as long as the multicast group continues to receive traffic. The Forwarded counter reflects activity for the particular cable interface and is reset to zero whenever the interface is shut down and reenabled. All packet counters are also automatically reset to zero if the DSG tunnel does not receive traffic for three minutes or more.

Command History

Release
Modification

12.3BC

This command was introduced

12.2(33)SCC

This command was integrated into Cisco IOS Release 12.2(33)SCC.


Usage Guidelines

Use the show cable fiber-node command to display information about a fiber node, such as the fiber node status. If you specify the spectrum parameter, the command displays upstream channel frequency assignment information and the spectrum group number.

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. This traditional DOCSIS downstream channel used for a MAC domain is called the primary downstream channel. The associated traditional DOCSIS upstream channel is used for return data traffic and signaling.

Examples

The following is a sample output of the show cable fiber-node command:

Router# show cable fiber-node 2
Fiber-Node         Config Status
Fiber-Node 2 
       downstream Modular-Cable 1/0/0:  0-3

Command History

Release
Modification

11.3 NA

This command was introduced.

12.0(3)T

This command was supported on the Cisco mainline release.

12.0(7)XR and 12.1(1a)T1

The output of this command was enhanced to show that the Cisco CMTS has detected an unstable return path for a particular CM and has compensated with a power adjustment. An asterisk (*) appears in the power adjustment field for a modem when a power adjustment has been made; an exclamation point (!) appears when the CM has reached its maximum power transmit level and cannot increase its power level further.

12.2(33)SCA

This command was integrated into Cisco IOS Release 12.2(33)SCA. Support for the Cisco uBR7225VXR router was added.

12.2(33)SCC

The output of this command was modified to show the aggregated data across all upstream channels for each flap detector for CMs in the Multiple Transmit Channel (MTC) mode on a Cisco uBR10012 router.


Usage Guidelines

The sort options operate differently on the different Cisco CMTS routers. On the Cisco uBR7100 series and Cisco uBR7200 series routers, the sort options apply to all cable interface line cards and merge the output into a single display.

On the Cisco uBR10012 router, the sort options apply to individual cable interfaces. For example, the sort-time option sorts all of the flap entries on the first cable interface (c5/0/0), then the entries on the second cable interface (c5/0/1), and so forth.


Note Occasionally, the show cable flap-list command might temporarily show duplicate entries for the same cable modem. This can occur after a cable modem has gone offline and before it has completed the registration process and come back online. When the cable modem does reach the online state, the duplicate entries disappear.



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 the output of the show cable flap-list command:

router# show cable flap-list

Table 1 describes the significant fields shown in the display.

Table 63 show cable flap-list Command Field Descriptions 

Field
Description

Mac Addr

The MAC address for the CM.

CableIF

The cable interface line card, including upstream, for this CM.

Ins

The number of times the CM comes up and inserts itself into the network. This counter is indicates the number of times the RF link was abnormally reestablished into the network. This counter is increased when the time between initial link establishment and a reestablishment was less than the threshold parameter configured using the cable flap-list insertion-time command.

Normal modem activity uses the following sequence:

Initial link insertion is followed by a station maintenance message between the CMTS and cable modem.

Power on

Initial maintenance

Station maintenance

Power off

When the link is broken, initial maintenance is repeated to reestablish the link.

Initial maintenance @ Time T1

Station maintenance

Initial maintenance @ Time T2

The Ins and Flap counters in the flap list are incremented whenever T2 - T1 < N where N is the insertion-time parameter configured in the cable flap-list insertion-time command.

This count may indicate intermittent downstream synchronization loss or DHCP or modem registration problems. In the latter case, the Ins count tends to track the Flap count. If the downstream is unstable (levels move outside the modem's range occasionally), insertions can occur. If the modem cannot provision correctly, many insertions occur.

If link reestablishment happens too frequently, the modem usually has a registration problem. To check for this potential problem, check to see if the insertion counter is the same order of magnitude as the Flap counter.

Hit

The number of times the CM responds to MAC-layer station maintenance (keepalive) messages. (The minimum hit rate is once per 30 seconds. It can indicate intermittent upstream, laser clipping, or common-path distortion.

Miss

The number of times the CM misses and does not respond to a MAC-layer station maintenance (keepalive) message. An 8 percent miss rate is normal for the Cisco cable interface line cards. It can indicate intermittent upstream, laser clipping, or common-path distortion.

Note The Hit and Miss columns are keepalive polling statistics between the CMTS and the cable modem. The station maintenance process occurs for every modem approximately every 25 seconds. When the CMTS receives a response from the modem, the event is counted as a hit. If the CMTS does not receive a response from the cable modem, the event is counted as a miss.

Ideally, the hit count should be much greater than the miss count. If a modem has a hit count much less than its miss count, then registration is failing. Noisy links cause the miss or hit ratio to deviate from a nominal 10 percent or less. High miss counts can indicate:

Intermittent upstream possibly due to noise

Laser clipping

Common-path distortion

Ingress or interference

Too much or too little upstream attenuation

A cable modem fails to respond either because of noise or if it is down. Modems that log only misses and zero hits are assumed to be powered off. If noise caused a poll to be missed, then the transition from miss to hit is detected as a flap condition. The poll rate is increased to 1 per second whenever the modem misses a poll. This is used to accelerate the offline state detection and decrease station maintenance overhead.

Misses are not desirable, because they usually indicate a return path problem; however, having a small number of misses is normal. After 16 misses, the modem is assumed to have powered off and the link is broken.

The flap count is incremented if there are M consecutive misses, where M is configured in the cable flap miss-threshold command. The parameter value ranges from 1 to 12, with a default of 6.

Hit and miss analysis could be done after the Ins count stops incrementing. In general, if the hit and miss counts are about the same order of magnitude, and the CRC count is low or nonexistent, then the upstream is experiencing noise.

If the miss count is greater, then the modem is probably experiencing common-path distortion and is dropping out frequently or not completing registration. Check grounding connections and if you see noise disappear after breaking a cable connection, but build back up again later, check the end-of-line terminators. You may be using a substandard frequency translator instead of a Digital Signal Processor. If the line is simply noisy, but not too noisy, you see an increase in the percentage of misses. If it is very noisy, then more than 80% of the ranging responses (RNG-RSP) are missed and the modem has many insertions.

CRC

The number of cyclic redundancy check (CRC) errors for this cable modem. CRC errors are calculated on per modem basis and refer to upstream impairments. Cable modems with high CRC errors either have bad upstream paths, or have in-home wiring problems.

The CRC counter field indicates:

Intermittent upstream

Laser clipping

Common-path distortion

Impulsive noise or interference

P-Adj

The number of times the headend instructed the CM to adjust transmit (TX) power more than 3 dB. It can indicate amplifier degradation, poor connections, or thermal sensitivity.

* means the noise power-adjustment method is active for this modem.

! means the modem has reached its maximum transmit power.

The station maintenance poll in the CMTS constantly adjusts the modem transmit power, frequency, and timing. The power-adjustment (P-Adj) column indicates the number of times the modem's power adjustment exceeded the threshold value. The power adjustment threshold may be set using the cable flap-list power-adjust threshold command with a value range of 0 to 10 dB and a default value of 2 dB. Tuning this threshold is recommended to decrease irrelevant entries in the flap list. Power-adjustment values of 2 dB and below continuously increment the P-Adj counter. The modem transmitter step size is 1.5 dB, whereas the headend may command 0.25 dB step sizes.

Power-adjustment flap strongly suggests upstream plant problems such as:

Amplifier degradation

Poor connections

Thermal sensitivity

Attenuation problem

The P-Adj column is often watched as an indicator of plant stability. It may give a forewarning of a future plant outage. If the upstream path contains too much or too little loss, the modem is undergoing many power adjustments.

Flap

The total number of times a modem has flapped, which is the sum of P-Adj and Ins values. This counter is incremented when one of the following events is detected:

Unusual modem insertion or re-registration attempts. The Flap and the Ins counters are incremented when the modem tries to reestablish the RF link with the CMTS within a period of time that is less than the user-configured insertion interval value.

Abnormal miss or hit ratio. The Flap counter is incremented when N consecutive misses are detected after a hit where N can be user-configured with a default value of 6.

Unusual power adjustment. The Flap and P-Adj counters are incremented when the modem's upstream power is adjusted beyond a user-configured power level.

Time

Time is the most recent time that the modem dropped the connection or flapped. The value is based on the clock configured on the local CMTS. If no time is configured, this value is based on the current uptime of the CMTS. When a cable modem meets one of the three flap list criteria, the Flap counter is incremental and Time is set to the current time.

Note This field displays a value in brackets in the output of the show cable modem flap command to indicate the duration (milliseconds) between the cable interface to become active and the first ranging success after a line card switchover (cable modem recovery time).

Usage Guidelines

You must enable the Cable IPC Statistics Collection tool using the cable ipc-stats command before using the show cable ipc-stats command. When you use this show command, a separate shadow database buffer is allocated, and the contents of the active database are copied into the shadow database to display the IPC statistics. This ensures that all the statistics are frozen at the same time for easy comparison and analysis.

Modification

12.2(15)BC2

This command was introduced for Cisco uBR7246VXR universal broadband routers.

12.2(33)SCA

This command was integrated into Cisco IOS Release 12.2(33)SCA on the Cisco uBR7246VXR and Cisco uBR10012 universal broadband routers. Support for the Cisco uBR7225VXR router was added. The vpn keyword was added and the output fields were modified to display L2VPN information.


Usage Guidelines

This command displays the cable modem to VLAN mappings that have been defined using the cable dot1q-vc-map command. It displays the MAC address, service ID (SID), and cable interface being used by the cable modem, and the interface and VLAN ID to which it has been mapped.


Tip The customer option displays only those VLAN mappings that have been configured with a particular customer name, using the cable dot1q-vc-map command.


The command also displays L2VPN information for cable modem traffic and service flows on CMTS router Ethernet interfaces that have been defined using the cable l2-vpn-service default-nsi command.

show cable load-balance

To display real-time configuration, statistical and operational information for load balancing operations on the router, use the show cable load-balance command in privileged EXEC mode.

show cable load-balance [[group n] | [all | load | pending | statistics | target | fiber-node-validation | vdoc]]

Syntax Description

group n

(Optional) Specifies the number of the load balancing group to be displayed.
In Cisco IOS Release 12.2(33)SCE3 and earlier, the valid range is from 1 to 336. The range from 1 to 80 is reserved for legacy load balancing groups (LBG). The range from 81 to 336 is reserved for DOCSIS LBGs.

In Cisco IOS Release 12.2(33)SCE4 and later, the valid range is from 1 to 256. This range is reserved for legacy LBGs only.

all

(Optional) Displays all information about the LBG.

load

(Optional) Displays the current interface load and load balancing group assignments.

pending

(Optional) Displays the list of cable modems that are moved from one downstream or upstream to another.

statistics

(Optional) Displays cumulative statistics for load balancing operations.

target

(Optional) Displays the current and target interfaces (upstreams and downstreams) used for load balancing.

fiber-node-validation

(Optional) Displays DOCSIS LBG and channel information after checking if the channel configuration in load balancing fits in the fiber node configuration.

vdoc

(Optional) Displays information about all LBGs that have the rule "video-over-DOCSIS (vdoc)-enabled" configured.


Defaults

Table 1 describes the fields shown in the show cable load-balance command displays.

Table 74 show cable load-balance Field Descriptions (default display) 

Field
Description
Fields for the Default Displays and load Option

Group Index

Identifies the mapping between the legacy LBG ID and the internal group index of the legacy LBG.

Interface

Cable interface (downstream or upstream) that belongs to a load balancing group.

Group

Number of the load balancing group to which the cable interface has been assigned.

Utilization

This field is a long-term average of the upstream utilization and displays current load usage of the cable interface expressed as a percentage of the total bandwidth. For upstreams, this field shows a single percentage value, which is the average percentage of bandwidth being used on the upstream.

For downstreams, this field shows a set of three percentage values:

The percentage shows the load usage for the entire interface.

The first percentage, within the parentheses, shows the load for the downstream.

The second percentage, within the parentheses, shows the average load for all upstreams on the downstream.

For example, if this field shows 18%(18%/12%), it indicates that downstream and upstream channels on the interface are running on an average load of 18 percent. The downstream is running on an average load of 18 percent and all upstreams for this downstream are running on an average load of 12 percent.

Note To view the short-term average of the utilization, use the show interface cable mac-scheduler command.

State

Current state of the cable interface.

The following states indicate normal operational states, depending on the configuration:

down—Interface is shut down. The CMTS cannot use the interface for load balancing in this state.

initial—Interface is currently in the initialization phase. The CMTS uses the interface for load balancing after the initialization completes.

up—Interface is up and passing traffic. The CMTS actively uses the interface for load balancing.

testing—Interface is currently under a load balancing test. The CMTS is unable to use the interface for normal load balancing operations until the test completes.

The following states indicate abnormal states. The CMTS does not use interfaces in these states for load balancing operations, but continues to monitor and update the status every time the CMTS polls the interfaces for their current load usage:

suspicious—Interface is in an unknown state. The interface might be up and passing traffic, but is not consistent enough to support load balancing operations. The CMTS attempts to reinitialize the interface after a timeout period. If the interface has failed initialization more than 10 times, the CMTS moves the interface to the disabled state.

disabled—Interface has been disabled because a load balancing test is in-progress or because the interface reinitialization failed after 10 attempts.

unstable—Interface has failed repeated initialization attempts. The CMTS will attempt to reinitialize the interface after a timeout period. If a load balance test is not in-progress and if reinitialization fails, the CMTS moves it to the unstable state.

Reserved

Percentage of bandwidth that is currently reserved by unsolicited grant service (UGS) service flows.

Modems

Number of cable modems currently online on this cable interface.

Flows

Number of service flows currently active on the cable interface.

Weight

Interface bandwidth, in megabits per second (mbps), for the downstream or upstream. The system uses this value in calculating whether the loads on the interfaces are balanced. Changing a channel parameter, such as modulation profile or channel width, affects the channel bandwidth and weight value.

Additional Fields When Displaying Load Balancing Groups

Interval

Indicates in seconds, the current load on each cable interface in the LBG as configured using the cable load-balance group interval command.

Method

Load balancing method used for the LBG as configured using the cable load-balance group (global configuration) command.

Threshold

Thresholds configured for this load balancing group:

M = Minimum

Minimum difference in the number of cable modems or service flows that can exist on two interfaces in the group before cable modems are moved between the interfaces. If the imbalance between interfaces is below this value, cable modems are not moved. This field contains a value only when the group is configured for the modems or service flows method of load balancing. (This value is configured using the load minimum option of the cable load-balance group threshold command.)

S = Static

Minimum difference in the percentage of total load that must exist between interfaces in a load balancing group before the Cisco CMTS performs static load balancing. When the load between interfaces is greater than this value, cable modems that are in the process of registering with the CMTS are moved between interfaces until the load difference is again below this value. (This value is configured using the load option of the cable load-balance group threshold command.)

E = Enforce

Minimum difference in the percentage of total load that must exist between interfaces in a load balancing group before the Cisco CMTS performs dynamic load balancing and begins moving cable modems that are currently online. When the difference in load between two interfaces falls below this value, the CMTS stops dynamic load balancing and performs static load balancing. (This value is configured using the enforce option of the cable load-balance group threshold command.)

U = Ugs

Percentage of the bandwidth that is allocated for Unsolicited Grant Services (UGS) traffic, such as Voice-over-IP (VoIP), that is in use on an interface because the CMTS moves cable modems that are online with active UGS service flows. (This value is configured using the ugs option of the cable load-balance group threshold command.)

P = PacketCable MultiMedia (PCMM)

Percentage of the reserved bandwidth threshold. Above this level, cable modems with active PCMM service flows participate in load balancing. The default threshold is 70%.

Additional Fields for the target Option

Interface

Source downstream or upstream interface that is part of a cable load balancing group. If the Target field contains a value, it indicates that the source interface is currently oversubscribed. To reduce the cable load, the CMTS moves cable modems from the source interface to the target interface.

Target

Downstream or upstream interface to which cable modems on the source interface are being moved as part of load balancing operations. This field indicates the following:

If it is a downstream interface, the display shows the center frequency of the downstream within parentheses.

If only a frequency is shown, it indicates that the CMTS is moving cable modems to a different center frequency on the same downstream interface.

When the display includes the words "enforce", it indicates that the CMTS is performing dynamic load balancing on the interfaces.

If this field is blank, it indicates that the source interface is not oversubscribed.

Additional Fields for the statistics Option

Target interface

Downstream or upstream interface. If this is a downstream interface, the display shows the center frequency of the downstream within parentheses.

Transfers

The following information is tracked for the indicated target interface:

complete—Number of cable modems successfully moved to the target interface.

pending—Number of cable modems in the process of being moved to the target interface.

retries—Number of times that the CMTS unsuccessfully tried to move the same cable modem to the target interface. This occurs when one or more MAC layer messages to the cable modem are dropped due to radio frequency (RF) noise or because the modem is not DOCSIS-compliant. If the number of retries exceeds five for a particular cable modem, the CMTS counts this as a failure.

failures—Number of times that the CMTS exceeded the maximum number of allowable retries (5) when trying to move a particular cable modem to the target interface. A large number of failures could indicate one or more possible problems:

The specific cable modems are not DOCSIS-compliant.

One or both interfaces are having problems passing traffic.

One or both interfaces are having persistent RF noise problems.

The source and target interfaces are not combined in the same node and do not share the same physical connectivity (which is required when interfaces are part the same load balancing group).

Additional Fields for the pending Option

Modem

Hardware (MAC) address of the cable modem that is moved as part of load balancing operations.

Source interface

Downstream or upstream cable interface on which the cable modem is currently online.

Target interface

Downstream or upstream cable interface to which the CMTS is trying to move the cable modem to load balance the interfaces in this load balancing group. If the CMTS is moving the cable modem to a different frequency on the same downstream interface, this field shows only the new center frequency.

Retries

Number of times that the CMTS has attempted to move this cable modem to the target interface. The CMTS attempts to move the cable modem 5 times before counting this load balancing move as a failure.

Additional Fields for the fiber-node-validation Option

DOCSIS LBG ID

The DOCSIS LBG ID.

Channel

The upstream or downstream channel that is associated with the DOCSIS LBG.

Fiber-node list

The list of all fiber nodes that include the channel.

Table 76 describes the fields shown in the show cable load-balance docsis-group display.

Table 76 show cable load-balance docsis-group - Field Description 

Field
Description
Fields for the Default Display and all Option

DOCSIS Group

Current number of DOCSIS groups created on the CMTS.

Group Index

Number of the load balancing group to which the cable interface has been assigned.

Status

Information about the DOCSIS LBG:

R—Restricted load balancing group (RLBG).

G—General load balancing group (GLBG).

E—The DOCSIS LBG is enabled.

D—The DOCSIS LBG is disabled.

Interval

Minimum time period configured when cable modems can be moved to load balance the interfaces.

In Cisco IOS Release 12.2(33)SCE and earlier releases, the valid range is 1 to 1000 seconds, with a default value of 10.
In Cisco IOS Release 12.2(33)SCE1 and later releases, the default value of interval is 30.

DCC mask/UCC

Downstream and upstream channel change masks associated with the DOCSIS group.

For example, in the output `0x40(1)/Y', `0x40' indicates that the user configured the dynamic channel change (DCC) technique 1 for the DOCSIS LBG. Similarly, '0x80' indicates configured DCC technique 0 and '0x20' indicates configured DCC technique 2. '(1)' indicates the DCC technique 1 is used to move the cable modem (CM). '/Y' indicates that load balancing sends upstream channel change (UCC) for movement of US channel only.

Policy

DOCSIS policy associated with the load balancing group.

Method

Load balancing method used for the load balancing group. The following indicates what method is used for DS and US modems:

m = modem

Uses the number of active cable modems on an interface.

s = service flow

Uses the number of active Service Flow IDs (SFIDs) on an interface.

u = utilization

Uses the current percent of utilization of an interface.

Threshold

Thresholds configured for this load balancing group:

M = Minimum

Minimum difference in the number of cable modems or service flows that can exist on two interfaces in the group before cable modems are moved between the interfaces. If the imbalance between interfaces is below this value, cable modems are not moved. This field contains a value only when the group is configured for the modems or service flows method of load balancing. (This value is configured using the load minimum option of the cable load-balance group threshold command.)

S = Stability.

Minimum allowable percentage of good periodic ranging requests that is acceptable. When the channel has a lower percent of modems responding to the ranging requests in a one minute period, the Cisco CMTS begins moving modems. The valid range is 0 to 100 percent, with a default of 50 percent.

E = Enforce

Minimum difference in the percentage of total load that must exist between interfaces in a load balancing group before the Cisco CMTS performs dynamic load balancing and begins moving cable modems that are currently online. When the difference in load between two interfaces falls below this value, the CMTS stops dynamic load balancing and performs static load balancing. (This value is configured using the enforce option of the cable load-balance group threshold command.)

U = Ugs

Percentage of the bandwidth that is allocated for Unsolicited Grant Services (UGS) traffic, such as Voice-over-IP (VoIP), that is in use on an interface because the CMTS moves cable modems that are online with active UGS service flows. (This value is configured using the ugs option of the cable load-balance group threshold command.)

P = PacketCable MultiMedia (PCMM)

Percentage of the reserved bandwidth threshold. Above this level, cable modems with active PCMM service flows participate in load balancing. The default threshold is 70%.

Interface

Cable interface (downstream or upstream) that belongs to a load balancing group.

Utilization

Long-term average of the upstream utilization. Displays the current load usage of the cable interface expressed as a percentage of the total bandwidth. For upstreams, this field shows a single percentage value, which is the average percentage of bandwidth being used on the upstream.

For downstreams, this field shows a set of three percentage values:

The percentage shows the load usage for the entire interface.

The first percentage, within the parentheses, shows the load for the downstream.

The second percentage, within the parentheses, shows the average load for all upstreams on the downstream.

For example, if this field shows " ", it indicates that downstream and upstream channels on the interface are running on an average load of 18 percent. The downstream is running on an average load of 18 percent and all upstreams for this downstream are running on an average load of 12 percent.

Note To view the short-term average of the utilization, use the show interface cable mac-scheduler command.

State

Current state of the cable interface.

The following states indicate normal operational states, depending on the configuration:

down—Interface is shut down. The CMTS cannot use the interface for load balancing in this state.

initial—Interface is currently in the initialization phase. The CMTS uses the interface for load balancing after the initialization completes.

up—Interface is up and passing traffic. The CMTS actively uses the interface for load balancing.

testing—Interface is currently under a load balancing test. The CMTS is unable to use the interface for normal load balancing operations until the test completes.

The following states indicate abnormal states. The CMTS does not use interfaces in these states for load balancing operations, but continues to monitor and update the status every time the CMTS polls the interfaces for their current load usage:

suspicious—Interface is in an unknown state. The interface might be up and passing traffic, but is not consistent enough to support load balancing operations. The CMTS attempts to reinitialize the interface after a time-out period. If the interface has failed initialization more than 10 times, the CMTS moves the interface to the disabled state.

disabled—Interface has been disabled because a load balancing test is in-progress or because the interface reinitialization failed after 10 attempts.

unstable—Interface has failed repeated initialization attempts. The CMTS will attempt to reinitialize the interface after a time-out period. If a load balance test is not in-progress and if reinitialization fails, the CMTS moves it to the unstable state.

Reserved

Percentage of bandwidth that is currently reserved by unsolicited grant service (UGS) service flows.

Modems

Number of cable modems currently online on this cable interface.

Flows

Number of service flows currently active on the cable interface.

Weight

Interface bandwidth, in megabits per second (mbps), for the downstream or upstream. The system uses this value in calculating whether the loads on the interfaces are balanced. Changing a channel parameter, such as modulation profile or channel width, affects the channel bandwidth and weight value.

 
Additional Fields for the target Option

Interface

Source downstream or upstream interface that is part of a cable load balancing group. If the target field contains a value, it indicates that the source interface is currently oversubscribed.

To reduce the cable load, the CMTS moves cable modems from the source interface to the target interface.

Target

Downstream or upstream interface to which cable modems on the source interface are being moved as part of load balancing operations. This field indicates the following:

If it is a downstream interface, the display shows the center frequency of the downstream within parentheses.

If only a frequency is shown, it indicates that the CMTS is moving cable modems to a different center frequency on the same downstream interface.

When the display includes the words "enforce", it indicates that the CMTS is performing dynamic load balancing on the interfaces.

If this field is blank, it indicates that the source interface is not oversubscribed.

Additional Fields for the statistics Option

Target interface

Downstream or upstream interface. If this is a downstream interface, the display shows the center frequency of the downstream within parentheses.

Transfers

The following information is tracked for the indicated target interface:

complete—Number of cable modems successfully moved to the target interface.

pending—Number of cable modems in the process of being moved to the target interface.

retries—Number of times that the CMTS unsuccessfully tried to move the same cable modem to the target interface. This occurs when one or more MAC layer messages to the cable modem are dropped due to radio frequency (RF) noise or because the modem is not DOCSIS-compliant. If the number of retries exceeds five for a particular cable modem, the CMTS counts this as a failure.

failures—Number of times that the CMTS exceeded the maximum number of allowable retries (5) when trying to move a particular cable modem to the target interface. A large number of failures could indicate one or more possible problems:

The specific cable modems are not DOCSIS-compliant.

One or both interfaces are having problems passing traffic.

One or both interfaces are having persistent RF noise problems.

The source and target interfaces are not combined in the same node and do not share the same physical connectivity (which is required when interfaces are part the same load balancing group).

Additional Fields for the pending Option

Modem

Hardware (MAC) address of the cable modem that is moved as part of load balancing operations.

Source interface

Downstream or upstream cable interface on which the cable modem is currently online.

Target interface

Downstream or upstream cable interface to which the CMTS is trying to move the cable modem to load balance the interfaces in this load balancing group. If the CMTS is moving the cable modem to a different frequency on the same downstream interface, this field shows only the new center frequency.

Retries

Number of times that the CMTS has attempted to move this cable modem to the target interface. The CMTS attempts to move the cable modem 5 times before counting this load balancing move as a failure.

Additional Fields for the modem-list option

US

Upstream channels in the DOCSIS LBG.

MAC Address

Total number (in parentheses) and MAC addresses of the modems connected to the upstream channels.

The


Usage Guidelines

For additional information about the Cable Duplicate MAC Address Reject feature on the Cisco CMTS, or enforced DOCSIS 1.1 security, see the Cable Duplicate MAC Address Reject for the Cisco CMTS.

The cable logging badipsource command creates a circular buffer that contains the BADIPSOURCE error messages, which the Cisco CMTS generates when it discovers a CM or CPE device using an unauthorized IP address. If the buffer becomes full, the oldest messages are deleted to make room for the newer messages.

Use the show cable logging command to display the current contents of the buffer. After you have viewed all of the error messages in the current buffer, use the clear cable logging command to clear out the buffer to make room for newer messages.

Use the show cable logging summary command to check if the logging feature is enabled and also to view the status of the logging buffer.

The Broadband Processing Engine (BPE) cable interface line cards (such as the Cisco uBR-MC16U/X and Cisco uBR-MC28U/X) contain an onboard processor that also maintains its own log buffer. To display the contents of this log, add the card slot number after the show cable logging command.
