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

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.
