The C4/c CMTS will generate notice-level logging when disruption in modem ranging occurs on a non-primary channel. For
example:
12:26:25 13 notc: MAC=00:15:a4:a4:58:1f; Upstream portNumber 3; SMRanger - Ranging opportunities
exceeded on non-primary upstream. Removed non-primary upstream from service flows.
12:27:39 13 notc: MAC=00:15:a4:a4:58:1f; Upstream portNumber 3; SMRanger - Non-primary upstream
resumed response to ranging opportunities. Restored non-primary upstream to service flows.
The output of the show cable modem detail command reflects when a CM is in an impaired state. The following is an
example of the output:

The show cable modem bonded-impaired command provides information on CMs that are not functioning at full capacity.
It also states the reason for the impaired state. (See for more details.)
