Command Reference

This section describes the commands used in Cisco IOS Release 12.0(5)T for troubleshooting the cable side of the Cisco uBR924 cable access router.

The commands used to troubleshoot VoIP applications are documented in the Cisco IOS

Release 12.0 command references.

show controllers cable-modem

show controllers cable-modem bpkm

show controllers cable-modem des

show controllers cable-modem filters

show controllers cable-modemlookup-table

show controllers cable-modem mac

show controllers cable-modem phy

show controllers cable-modem tuner

In Cisco IOS Release 12.0(1)T or later, you can search and filter the output for show and more commands. This functionality is useful when you need to sort through large amounts of output, or if you want to exclude output that you do not need to see.

To use this functionality, enter a show or more command followed by the “pipe” character (), one of the keywords begin, include, or exclude, and an expression that you want to search or filter on:

command {begin include exclude} regular-expression

Following is an example of the show atm vc command in which you want the command output to begin with the first line where the expression “PeakRate” appears:

show atm vc begin PeakRate

For more information on the search and filter functionality, refer to the Cisco IOS Release 12.0(1)T feature module titled CLI String Search.
