Command History

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

When you enable debugging on a switch stack, 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.
