|
channel-group
To add an interface (Gigabit Ethernet or Fast Ethernet) to an EtherChannel Group, and to associate that interface with an EtherChannel link, use the channel-group command in interface configuration mode.
To remove an EtherChannel interface from the EtherChannel group, use the no form of this command.
channel-group n
no channel-group n
Syntax Description
n
|
The identifying number for the EtherChannel group with which to associate this interface. An EtherChannel group can be identified in the range of 1 to 64, and each group can have up to four interfaces, only one of which is the master.
|
Defaults
By default, the channel-group command has the following behaviors:
•
EtherChannel groups and ports are not defined.
•
EtherChannel groups and ports are disabled (off mode) once configured, and must be enabled.
•
The first port assigned to an EtherChannel group is the bundle master.

Modification
|
12.2(11)BC3
|
This command was introduced on the Cisco uBR7246VXR router.
|
12.2(9a)BC
|
This command was introduced on the Cisco uBR10012 router.
|
12.3BC

This command was integrated into Cisco IOS Release 12.3BC.
|
12.2(33)SCA
|
This command was integrated into Cisco IOS Release 12.2(33)SCA. Support for the Cisco uBR7225VXR router was added.
|
Usage Guidelines
The no form of this command also removes the associated EtherChannel ports within the EtherChannel group. For additional information, refer to the EtherChannel on the Cisco CMTS Routers feature document on Cisco.com.
Examples
The following example creates an EtherChannel link with a channel group identifier of 1 on the specified port. If this is the first port assigned to EtherChannel group 1, it becomes the master in that EtherChannel group.
Router(config-if)# channel-group etherchannel 1
Related Commands
Command
|
Description
|
show interface port-channel
|
Displays the EtherChannel interfaces and channel identifiers, with their mode and operational status.
|
channel-id (cable configuration file)
To create a DOCSIS configuration file that specifies the upstream channel ID for a CM configuration file, use the channel-id command in cable config-file configuration mode. To remove the channel ID specification, use the no form of this command.
channel-id upstreamchan-id
no channel-id
Syntax Description
upstreamchan-id
|
Specifies the upstream channel ID. Valid range is 0 to 255, depending on the number of actual upstream ports on the cable interface being used.
|
Defaults
If no upstream channel ID is specified, the CM uses the upstream channel from the Upstream Channel Description (UCD) messages it receives on the downstream channel.

This command was integrated into Cisco IOS Release 12.3BC.
|
12.2(33)SCA
|
This command was integrated into Cisco IOS Release 12.2(33)SCA. Support for the Cisco uBR7225VXR router was added.
|
Usage Guidelines
This command sets the Upstream Channel ID Configuration Setting field in the DOCSIS configuration file. Typically, the CM uses the upstream channel ID that is specified by the CMTS during the registration process, but this command overrides that setting and forces the CM to use the upstream channel specified in the DOCSIS configuration file. If that upstream does not exist, or if the upstream cannot be obtained for some reason, the CM cannot come online.
Note
If you are using a telco-return CM, the upstream channel must be 0.
Examples
The following example shows how to set the upstream channel ID for the configuration file to 3. If the CM cannot obtain this upstream channel, it does not come online.
Router(config)# cable config-file channeloverride.cm
Router(config-file)# channel-id 3
Router(config-file)# exit

• The name keyword option was added for specifying the fully-qualified domain name of a CM.
|
Usage Guidelines
This command removes a host's IP, MAC address, or domain name from the router's internal address tables. This might be necessary to allow a new host to come online from the previous host's CM.
Note
If the cleared host continues communicating through the CM, the Cisco CMTS adds the host back to its internal address tables, and the show interface cable interface modem command shows it as having a "static" address. To block the host from any further access, use the cable source-verify dhcp command, so that the host cannot access the network unless it obtains an IP address from an authorized DHCP server.
Note
In Cisco IOS Release 12.2(33)SCA, the show cable modem domain-name command must be run first on the route processor (RP) of the CMTS router before any domain name can be used as part of a cable command.
Examples
The following example shows how to remove a host's MAC address from the internal address tables on the Cisco CMTS router:
Router# clear cable host 0050.7366.17ab

Usage Guidelines
The cable logging badipsource command creates a circular buffer that contains the BADIPSOURCE error messages that the Cisco CMTS generates when it discovers a CM or CPE device using an unauthorized IP address. When the buffer becomes full, the oldest messages are deleted to make room for newer messages.
When 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.
Examples
The following example shows how to clear the log buffer that contains the bad IP source address error messages:
Router# show cable logging summary
Cable logging: BADIPSOURCE Enabled
Total buffer size (bytes): 1000000
Used buffer size (bytes) : 36968
Router# clear cable logging badipsource
Router# show cable logging summary
Cable logging: BADIPSOURCE Enabled
Total buffer size (bytes): 1000000
Used buffer size (bytes) : 0
The following example shows how to clear the log buffer that contains the downstream index messages:
Router# show cable logging downstream-index
Total buffer size (bytes): 1000000
Used buffer size (bytes) : 36968
Router# clear cable logging downstream-index

Usage Guidelines
This command removes one or more CMs from the CMTS router memory, which causes the CMTS router to stop all DOCSIS station maintenance messages for the specified CMs until they time out and reattempt initial ranging.
Caution 
The
clear cable modem all delete command should normally be used only on a test or lab network. If used on a large network, it could impact service for a significant period of time, as it would force all CMs to simultaneously reset and reregister with the Cisco CMTS. In addition, if HCCP N+1 redundancy has also been configured, using the
clear cable modem delete command can trigger a switchover to one or more Protect interfaces, unless
no keepalive has also been configured on the cable interfaces.
Examples
The following example shows how to delete the CM at IP address 172.23.45.67:
Router# clear cable modem 172.23.45.67 delete
The following example shows how to delete all CMs that have a OUI that has been defined as having the vendor name of Cisco using the cable modem vendor command:

Usage Guidelines
When you have configured the cable dynamic-secret lock command on a cable interface, the CMTS "locks" CMs that use a DOCSIS configuration file that fails the CMTS verification check. These CMs are allowed to come online, but with a restrictive QoS configuration that limits their service flows to 10 kbps.
Locked CMs are not allowed to reregister with a valid DOCSIS configuration file until they have been offline, without attempting to reregister, for at least 24 hours. You can manually clear the lock on a CM by using the clear cable modem lock command in privileged EXEC mode.
The clear cable modem lock command also automatically resets the CMs, so that they will reregister with the CMTS. If the CMs then reregister with a valid DOCSIS configuration file, the CMTS allows the CMs to come online with the requested QoS profiles. If the CMs violate the DOCSIS specifications again, they will be locked again.
Note
If a CM is not manually unlocked, it remains locked until it stays offline, without attempting to reregister, for 24 hours. It can also be unlocked by using the clear cable modem delete command to manually remove the CM from all of the CMTS internal databases.
Examples
The following example shows how to reset the lock for the CM with the MAC address of 0000.0C01.0203:
Router# clear cable modem 0000.0C01.0203 lock
The following example shows how to reset the lock for the CM at IP address 172.16.23.45:

|
This command was integrated into Cisco IOS Release 12.2(33)SCA, with the following changes:
• Support for the Cisco uBR7225VXR router was added.
• Support for specifying the IPv6 address of a CM was added.
|
Usage Guidelines
This command instructs the Cisco CMTS to stop sending DOCSIS station maintenance messages to one or more CMs, which effectively terminates the link to those CMs until those CMs time out and reattempt initial ranging. A CM responds to this by resetting itself. Depending on when the CM received the last station maintenance message, it can take up to 30 seconds before the CM detects the missing station maintenance messages and resets itself.
If the clear cable modem {ip-address | mac-address} reset form of the command is used to reset an individual modem, the CMTS router sends a ranging abort message to the specified modem in order to command the modem to reset itself and begin initial ranging more quickly without having to wait for up to 30 seconds to realize it is no longer receiving station maintenance keep-alive opportunities. This behavior is only seen when using the clear cable modem reset command for a specific CM.
Tip
You can also specify the MAC address or IP address for a CPE device or host, and the Cisco CMTS resets the CM that is associated with that CPE device in its internal database.
In some circumstances, the customer premises equipment (CPE) device behind a CM stops receiving traffic after the CM is reset. This is because the CMTS still has the CPE device listed in its address tables, but the CM does not after being reset, so the traffic passes through the CMTS but is dropped by the CM. To resolve this situation, the CPE device should simply send some type of traffic to the CM, such as a ping packet. (You can also resolve this situation by using the clear arp-cache command on the Cisco CMTS router to clear the router's address table, but this is not recommended because it temporarily interrupts all traffic on the router.)
Caution 
The
clear cable modem all reset command should normally be used only on a test or lab network. If used on a large network, it could impact service for a significant period of time, as it would force all CMs to simultaneously reset and reregister with the Cisco CMTS.
Note
The clear cable modem all reset command can result in the CPU utilization temporarily reaching 100 percent for a couple of minutes, as the CPU processes the command for all CMs. The CPU utilization will return to normal within a couple of minutes.
Examples
The following example shows how to reset the CM at IP address 172.23.45.67:
Router# clear cable modem 172.23.45.67 reset
The following example shows how to reset all CMs that have an OUI that has been defined as having the vendor name of Cisco using the cable modem vendor command:
Router# clear cable modem oui Cisco reset
The following example shows how to reset all CMs that are currently in one of the reject states:
Router# clear cable modem reject reset
For the Cisco uBR10012 router, the following example shows how to reset all wideband CMs that are registered as traditional DOCSIS modems:

This command was integrated into Cisco IOS Release 12.2(33)SCA. Support for the Cisco uBR7225VXR router was added.
|
Usage Guidelines
To support BPI and BPI+ operations with CMs and CPE devices that use secondary IP addresses, the CMTS maintains a database that links the known secondary IP addresses to the SIDs used by those devices. When the CMTS and CM need to renew their public keys, the CMTS uses this database to ensure that all IP addresses are sufficiently updated to allow proper routing and fast switching.
Tip
You can display the list of known IP addresses per SID by using the show interface cable sid command.
If you encounter apparent problems with secondary IP addressing, or if you want to manually clear the table of IP addresses for a particular SID, use the clear cable secondary-ip command.
Tip
One possible situation that might occur is if a CM first assigns a secondary IP address to one CPE device, but later that same IP address is assigned to another CPE device behind a different CM. If this happens, the IP address will continue to show up as a secondary IP address for the original CM until that CM renews its public keys. This will not affect network connectivity for either CPE or CM. You can, however, clear the unneeded secondary IP address from the CMTS database using the clear cable secondary-ip command.
Examples
The following example shows how to clear all of the secondary IP addresses for a particular cable interface:
Router# clear cable secondary-ip interface cable 3/0 all
The following example shows how to clear the secondary IP addresses for all CM and CPE devices on cable interface 1/0 that are using SID 5:
Router# clear cable secondary-ip interface cable 1/0 sid 5
The following example shows how to clear the secondary IP addresses for the CM and CPE devices on cable interface 5/0 that are using SID 113 and IP address 10.10.17.3:
Router# clear cable secondary-ip interface cable 5/0 sid 113 10.10.17.3

Usage Guidelines
This feature allows you to change the Differentiated Services Code Point (DSCP) marking for COPS messages that are transmitted or received by the Cisco router. Cisco IOS Release 12.3(13a)BC supports this function with the cops ip dscp command. The cops ip dscp command changes the default IP parameters for connections between the Cisco router and COPS servers in the cable network.
DSCP values are used in Quality of Service (QoS) configurations on a Cisco router to summarize the relationship between DSCP and IP precedence. This command allows COPS to remark the packets for either incoming or outbound connections.
The default setting is 0 for outbound connections. On default incoming connections, the COPS engine takes the DSCP value from the COPS server initiating the TCP connection.
Note
This feature affects all TCP connections with all COPS servers.
•
The cops ip dscp command allows the Cisco router to re-mark the COPS packets for either incoming or outbound connections.
•
This command affects all TCP connections with all COPS servers.
•
This command does not affect existing connections to COPS servers. Once you issue this command, this function is supported only for new connections after that point in time.
•
For messages transmitted by the Cisco router, the default DSCP value is 0.
•
For incoming connections to the Cisco router, the COPS engine takes the DSCP value used by the COPS server that initiates the TCP connection, by default.
For additional information about this feature and related commands, refer to the "COPS Engine Operation on the Cisco CMTS Routers" feature document on Cisco.com.

Router(config)# cops ip dscp 0-63
The following example specifies the COPS server and enables COPS for RSVP on the server. Both of these functions are accomplished by using the ip rsvp policy cops command. By implication, the default settings for all remaining COPS for RSVP commands are accepted.
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# ip rsvp policy cops servers 161.44.130.168 161.44.129.6
The following examples display three views of the COPS for RSVP configuration on the router, which can be used to verify the COPS for RSVP configuration.
The following example displays the policy server address, state, keepalives, and policy client information:
Router# show cops servers
COPS SERVER: Address: 161.44.135.172. Port: 3288. State: 0. Keepalive: 120 sec
Number of clients: 1. Number of sessions: 1.
COPS CLIENT: Client type: 1. State: 0.
The following example displays the policy server address, the ACL ID, and the client/server connection status:
Router# show ip rsvp policy cops
COPS/RSVP entry. ACLs: 40 60
Currently connected to PDP 161.44.135.172, port 0
The following example displays the ACL ID numbers and the status for each ACL ID:
Router# show ip rsvp policy
Local policy: Currently unsupported
ACLs: 40 60 . State: CONNECTED.
ACLs: 40 160 . State: CONNECTING.
