Monitoring Vtp - Cisco Catalyst 3550 series Software Configuration Manual

Chapter 13 Configuring VTP
Note You can use the vtp mode transparent global configuration command or the vtp transparent VLAN
configuration command to disable VTP on the switch, and then change its VLAN information without
affecting the other switches in the VTP domain.

Monitoring VTP

You monitor VTP by displaying VTP configuration information: the domain name, the current VTP
revision, and the number of VLANs. You can also display statistics about the advertisements sent and
received by the switch.
