Command Modes Privileged EXEC

Command History

Usage Guidelines Entering the debug mka command with no keywords enables all MKA debugging facilities.

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 starting a session.
