Today I was doing my daily lab and found a nice command for VTP:
IOU4#show vtp devices
Retrieving information from the VTP domain. Waiting for 5 seconds.
VTP Feature Conf Revision Primary Server Device ID Device Description
———— —- ——– ————– ————– ———————-
VLAN No 2 aabb.cc80.0600 aabb.cc80.0200 IOU3
VLAN No 2 aabb.cc80.0600 aabb.cc80.0500 IOU1
VLAN No 2 aabb.cc80.0600=aabb.cc80.0600 IOU2
This command shows nicely what devices you have in your VTP domain and what is their view of the VTP domain. Nice.
