Usage Guidelines
The undebug etherchannel command is the same as the no debug etherchannel command.
When you enable debugging on a stack, it is enabled only on the active switch. To enable debugging on the
standby switch , start a session from the active switch by using the session switch-number command in
privileged EXEC mode. Enter the debug command at the command-line prompt of the standby switch.
To enable debugging on the standby switch without first starting a session on the active switch, use the remote
command switch-number LINE command in privileged EXEC mode.
