Usage Guidelines

The undebug spanning-tree backbonefast command is the same as the no debug spanning-tree

backbonefast 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.
