Syntax Description maintenance
When a CM is detected to be offline by the CMTS—no reply after 16 retries of station maintenance
requests—the CM is marked offline. Besides marking the CM and service identifier (SID) state offline,
the SID is removed immediately from the CMTS ranging list, and an aging timer is started to clean up
the SID completely if the CM does not attempt to come online within the next 24 hours.

Displays station maintenance error statistics.
The SM Exhausted Count value refers to the number of times a CM was dropped because it did not
reply to station maintenance requests. A CM is removed from the station maintenance list after 16
times of periodic ranging opportunity without seeing the RNG_REQ from the modem.
The SM Aborted Count value refers to the number of times the CM was dropped because its
operational parameters were unacceptable. This includes such reasons as the power level is outside
the acceptable range, or the timing offset keeps changing. The respective times in the command
output indicate when this happened.
