This table describes the significant fields for the show cable admission-control command for upstream and downstream throughput.
|
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: |
|
# of Rejec |
Number of rejections. |
|
Sched Type |
Available for upstream only. This field displays the following information: |
|
Flow Type |
Available for Downstream only. This field displays voice and data information: |
|
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 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.

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.

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).

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.

Modification |
|---|---|
|
12.1(1a)T1 |
This command was introduced. |
|
12.1(2)EC1 |
This command was supported on the EC train. |
|
12.2(1)XF1, 12.2(4)BC1 |
This command was supported for the Cisco uBR10012 universal broadband router. |
|
12.3(23)BC |
This command was supported for DTI mode. |
|
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 External T1 References: Card: 2/1 Primary T1 : Available Secondary T1: Available
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. |

Router(config)# interface c5/1 Router(config-if)# shutdown Router(config-if)# exit Router(config)# exit Router# show cable dsg stats vendor CCC DSG statistics information DSG keepalive is set Vendor: CCC, Tunnel count: 1 Vendor name is CCC, tunnel MAC is 0005.0006.0007 Group address is 228.3.3.3, source address is * Interface is Cable5/1, mapping entry is used 2 Router#
Table 0-1 describes the major fields shown in the show cable dsg command:
|
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.
|
||
|
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. |

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. |
|
IOS-XE 3.15.0S |
This command was implemented on the Cisco cBR-8 Converged Broadband Router. The upstream and sort-mac keywords were removed. |
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. |

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

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.

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:
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.
|
||
|
State |
Current state of the cable interface. The following states indicate normal operational states, depending on the configuration:
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:
|
||
|
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. |
||
|
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: 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.) 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.) 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.) 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.) |
||
|
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:
|
||
|
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:
|
||
|
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. |
||

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: |
||
|
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: Uses the number of active cable modems on an interface. Uses the number of active Service Flow IDs (SFIDs) on an interface. Uses the current percent of utilization of an interface. |
||
|
Threshold |
Thresholds configured for this load balancing group: 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.) 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. 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.) 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.) 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:
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.
|
||
|
State |
Current state of the cable interface. The following states indicate normal operational states, depending on the configuration:
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:
|
||
|
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. |
||
|
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:
|
||

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. Similarly, the cable logging layer2events command creates a buffer to contain the system messages that are generated for DOCSIS-layer (Layer2) events. If the BADIPSOURCE or DOCSIS-layer 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 BADIPSOURCE, downstream-index, or DOCSIS-layer 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.
Note | The BADIPSOURCE, downstream-index, and DOCSIS-layer messages are stored in separate buffers. Enabling, clearing, or displaying one buffer does not affect the other buffer. |
Examples
This example shows the output of the show cable logging badipsource command. The oldest messages are displayed first.
