Command History
Usage Guidelines The undebug backup command is the same as the no debug backup command.
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.
