Vtp status not updating

Please note that the behavior of VTP version 3 may not be the same as shown here.

In VTP version 2, transparent switches do forward received VTP advertisements out of their trunk ports, acting as VTP relays.

The VLAN Trunking Protocol (VTP) is a very handy protocol to create, manage and maintain a large network with many switches under same physical LAN.

The VLAN Trunking Protocol (VTP) can manage the addition, deletion, and renaming of VLANs from a central server without manual intervention and VLAN Trunk Protocol (VTP) thus reducing overhead on network administration.

A key ingredient of VTP is configuration revision number which is a 32-bit number that indicates the level of revision for a VTP packet.

Each VTP device tracks the VTP configuration revision number that is assigned to it.

Let’s create a VLAN on SW1 to verify that VTP is actually working.

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.

Here we change the switch VTP mode to “Transparent Mode”, and then switch back.

Our first test is configured the same for all the necessary interfaces of the switches.

Symptoms & environment as follows: * Have 2 switches connected.

* One switch is VTP Server and the other is client.
