Usage Guidelines
The undebug platform udld command is the same as the no debug platform udld command.
When you enable debugging on a switch stack, it is enabled only on the stack master. To enable debugging
on a stack member, start a session from the stack master by using the session switch-number command in
privileged EXEC mode. Enter the debug command at the command-line prompt of the stack member.
To enable debugging on a stack member without first starting a session on the stack master, use the remote
command switch-number LINE command in privileged EXEC mode.
