An assigned downstream channel ID
must not be assigned to any other logical
channel on the DCAM. The C4/c CMTS
does this automatically .
Channel Assignment Considerations
Prior to assigning a channel ID the following needs to be considered:
1. Before assigning a channel ID, the upstream or downstream channel, as well as the MAC domain must be shutdown.
2. The shutdowns would be accomplished by the commands shown in the following example:
Note: To change the channel ID of an upstream, the upstream's logical channel 0 (<slot>/<connector-
group>/<uport>.0) must be shutdown, as shown in the example.
configure interface cable-upstream 3/0/0.0 shutdown
configure interface cable-mac 1 shutdown
configure interface cable-downstream 12/0/0 shutdown
configure interface cable-mac 1 shutdown
3. The channel ID can now be changed.
Example Commands
