Cisco Prime - VTP Disconnected Domain Alarm

leonardomachado · ‎02-25-2014

sw03 is out of vtp domain, but it is, at same time, inside that same domain... how is that possible?

If I create a VLAN on sw01 (server) it is reflected to all clients (sw2 and sw3). So it's working as expected. Then, why this alarm?

Could someone explain me how to fix it?

If you are on LMS 4.2.4, it may be :

CSCuj62537 LMS 4.2.4 wrongly report VTP disconnected domain discrepancy

As this data is collected during Data collection, sometime one failing device for DC may report incorrect descrepancy. Please run a new Data Collection for all devices or you can open Topology Map from where you can right click on affected devices and run DC directly.

You may acknowledge the Descrepancy and run new DC and see if it re-occurs. Ideally this doesnt seems to be an issue now as the revision numbers are same on all the devices.

-Thanks

CSCuj62537 says:

Conditions:

VTP Domain with one device configured as VTP transparent.

But there is no VTP transparent mode involved in my case.

And yes, I have Cisco Prime 4.2 running.

I will ignore it for a while and check for new occurences
