Cisco IOS Release 12.3(9a)BC shortens the output of the show tech-support command on the Cisco
uBR10012 and the Cisco uBR7246VXR routers. This change allows users with large numbers of online
cable modems to collect information without consuming the console session for a long period of time.
To display general information about the Cisco CMTS router when reporting a problem to Cisco
technical support, use the show tech-support command in privileged EXEC mode.
The show tech-support command automatically displays the output of a number of different show
Note
commands. The exact output depends on the platform, configuration, and type of protocols being used.
Note The show tech-support includes most of the information shown in the
command.
