Usage Guidelines
The undebug sw-vlan vtp command is the same as the no debug sw-vlan vtp command.
If no further parameters are entered after the pruning keyword, VTP pruning debugging messages
appear. They are generated by the VTP_PRUNING_LOG_NOTICE, VTP_PRUNING_LOG_INFO,
VTP_PRUNING_LOG_DEBUG, VTP_PRUNING_LOG_ALERT, and
VTP_PRUNING_LOG_WARNING macros in the VTP pruning code.
