show cable modem maintenance
To display station maintenance error statistics, use the showcablemodemmaintenance command in
privileged EXEC mode.
showcablemodemmaintenance
Syntax Description
When a CM is detected to be offline by the CMTS—no reply after 16retries 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 24hours.
Output fields are described below:
• 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.
Examples The following example shows sample output for the maintenance option for a particular CM:
Router# show cable modem 0010.7bb3.fcd1 maintenance
MAC Address I/F Prim SM Exhausted SM Aborted
Sid Count Time Count Time
0010.7bb3.fcd1 C5/0/0/U5 1 3 Jun 1 10:24:52 0 Jan 1 00:00:00
show cable modulation-profile
To display modulation profile group information for a Cisco CMTS, use the
showcablemodulation-profile command in Privileged EXEC mode.
show cable modulation-profile [profile] [iuc-code]
Note Commencing with Cisco IOS Release 12.1(2)EC, this command replaced the show cable
burst-profile command. Commencing with Cisco IOS Release 12.1(3a)EC, the reqdata type option
was added.
