Command History
Usage Guidelines
The
undebug mvrdbg
command is the same as the
no debug mvrdbg
command.
On a stacking-capable switch, when you enable debugging, it is enabled only on the stack master. To
enable debugging on a stack member, you can start a session from the stack master by using the
session
switch-number
privileged EXEC command. Then enter the
debug
command at the command-line
prompt of the stack member. You also can use the
remote command
stack-member-number
LINE
privileged EXEC command on the stack master switch to enable debugging on a member switch without
first starting a session.
