channel-id
channel-id
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.
Syntax Description
upstreamchan-id
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.
Command Modes
Cable config-file configuration

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.
If you are using a telco-return CM, the upstream channel must be 0.
Note
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
