The undebug platform vlan command is the same as the no debug platform vlan command.
On a Catalyst 3750-E switch, 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.

The undebug udld command is the same as the no debug udld command.
On a Catalyst 3750-E switch, 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.
For debug udld events, these debugging messages appear:
•General UDLD program logic flow
•State machine state changes
•Program actions for the set and clear ErrDisable state
•Neighbor cache additions and deletions
•Processing of configuration commands
•Processing of link-up and link-down indications
For debug udld packets, these debugging messages appear:
•General packet processing program flow on receipt of an incoming packet
•Indications of the contents of the various pieces of packets received (such as type length versions [TLVs]) as they are examined by the packet reception code
•Packet transmission attempts and the outcome
For debug udld registries, these categories of debugging messages appear:
•Sub-block creation
•Fiber-port status changes
•State change indications from the port manager software
•MAC address registry calls
