Command History
Usage Guidelines
The
undebug mvrdbg
command is the same as the
no debug mvrdbg
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.
