Usage Guidelines
The undebug ip dhcp snooping command is the same as the no debug ip dhcp snooping command.
When you enable debugging on a switch stack, 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.
