Usage Guidelines
This command displays information about the number of times that a CM has exhausted its maximum
retry attempts to respond to a Station Maintenance (SM) request, as well as the number of times that the

used to determine whether a particular cable modem or interface is experiencing plant or network
difficulties.

cable interface, or for one particular cable modem.
