Table 1. 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.

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

Table 5. 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.

The following example displays the upstream and downstream AC information for the wideband-cable interface:

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.

IOS-XE 3.15.0S

This command was implemented on the Cisco cBR Series Converged Broadband Routers. The value ranges for the slot/subslot/port variables were changed.

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.

Router# 
Table 6. show cable arp-filter Field Descriptions in Cisco uBR10012 Router

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.

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

CPE IP

IP address of the CPE device.

Modem MAC

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

Modem IP

M/S

Type of filtering, M means per MAC filtering, S means per Sid filtering.

Rate

The rate of filtered packets, olny hardware assist filtering has the value.

Pro

Where is the filtering performed, with options RP and PXF(FP).

[REQ|REP|REQIP]

REQ means arp request packets, REP means arp reply, REQIP means arp request for IP.

Examples

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.

Modification

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.

12.2(33)SCH2

This command was modified. The mobility parameter was added.

IOS-XE 3.15.0S

This command was implemented on the Cisco cBR Series Converged Broadband Routers.

Usage Guidelines

  • For uBR series router, 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.
  • For uBR series router, in releases prior to Cisco IOS Release 12.3(21)BC, if you delete the virtual bundle interface, the virtual bundle disappears.
  • For uBR series router, 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).

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.

IOS-XE 3.15.0S

This command was implemented on the Cisco cBR Series Converged Broadband Routers.

Usage Guidelines

  • For uBR series router, 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.
  • For uBR series router, in releases prior to Cisco IOS Release 12.3(21)BC, if you delete the virtual bundle interface, the virtual bundle disappears.
  • For uBR series router, 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

12.2(44)SQ

This command was modified in Cisco IOS Release 12.2(44)SQ to support the Cisco RF Gateway 10. The slot , client , server , and counters options were added.

IOS-XE 3.15.0S

This command was implemented on the Cisco cBR Series Converged Broadband Routers. The dti keyword was added.

Usage Guidelines

This command supports the Cisco CMTS clock feature set, which provides a synchronized clock for improved Voice-over-IP (VoIP) operations. The clock feature set requires one of the following configurations:

  • A Cisco uBR10012 router with one or two TCC+ cards that are connected to an external national clock source.

Note


Beginning in Cisco IOS Release 12.3(23)BC, TCC+ is replaced with DOCSIS Timing and Control Card (DTCC).
  • 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:


Router# show cable clock
 
Number of TCCplus Cards in the Chassis: 2
Active TCCplus Card is in slot: 1 subslot: 1
Backup TCCplus Card is in slot: 2 subslot: 1
Clock reference used by the active card is Primary T1 
External T1 References:
Card: 1/1
Primary T1  : Available
Secondary T1: Available
Card: 2/1
Primary T1  : Available
Secondary T1: Available

The following sample output from the show cable clock command on a Cisco uBR10012 router shows that the TCC+ card in slot 1/1 is in maintenance mode, and that the TCC+ card in slot 2/1 is providing the clock reference:


Router# show cable clock
 
Number of TCCplus Cards in the Chassis: 2
TCCplus card in 1/1 under maintenance
Active TCCplus Card is in slot: 2 subslot: 1
Clock reference used by the active card is Primary T1
