Vtp database not updating

Rated 3.98/5 based on 661 customer reviews

The configuration revision number would also move to 4.

I recently replaced the switch that was functioning as the VLAN server for the rest of the network.

Will there be an update on either switch, will SW1 wait for a Server advertisement or will something else happen all together? A few hours have passed, and we have had over 50 comments , ideas and theories.

I appreciate you taking the time to work through this. SW1, will see that its configuration revision number is lower than SW2, and even though SW2 is a “client” SW1 will use the updated information in the VTP advertisement from SW2 to update to its VLAN database, and get in “sync” with the rest of the VTP domain, including knowing about VLAN 999.

Since the replacement however, I have not been able to push any new VLANs to the Client switches.

Is there any way to force the client VLAN database to be updated?

The main goal of VTP version 3 remains to synchronize VLANs but it has a number for extras.The old VLANs are all working fine -- it is just not receiving new ones.I've tried sh vtp status VTP Version capable : 1 to 3 VTP version running : 2 VTP Domain Name : abx VTP Pruning Mode : Disabled VTP Traps Generation : Disabled Device ID : 001b.d468.1e80 Configuration last modified by XX.
