Usage Guidelines
The undebug pagp command is the same as the no debug pagp command.
When you enable debugging, it is enabled only on the stack master. To enable debugging on a stack
member, you must 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.
