The VLAN Trunking Protocol (VTP) is a really helpful protocol to create, handle and preserve a big community with many switches beneath the identical bodily LAN.
The VLAN Trunking Protocol (VTP) can handle the addition, deletion, and renaming of VLANs from a central server with out guide intervention and VLAN Trunk Protocol (VTP) thus lowering overhead on community administration.
A key ingredient of VTP is configuration revision quantity which is a 32-bit quantity that signifies the extent of revision for a VTP packet.
Every VTP system tracks the VTP revision quantity that’s assigned to it. This info is used with a view to decide whether or not the obtained info is more moderen than the present model.

Strategies to Reset Revision Quantity in VTP
Every time that you just make a VLAN change in a VTP system, the configuration revision is incremented by one. Under we are going to focus on 2 generally used strategies to reset revision quantity configuration of a swap.
PROCEDURE 1
RESET THE CONFIGURATION REVISION NUMBER USING DOMAIN NAME:
The first process to reset the VTP configuration revision quantity is by altering the area identify after which reverting again the configuration. Under is the step-by-step technique to be adopted –
Step 1 –
present vtp standing command on Cisco Change with a view to examine the VTP configuration revision quantity.

Step 2 –
Go to the worldwide configuration mode and alter the VTP area identify on Cisco Change.
SW1#configure terminal
SW1(config)#vtp area ipwithease
Step 3 –
Once more change the VTP area identify again to preliminary area identify.
SW1(config)#vtp area CISCO
Step 4 –
Now examine the VTP configuration revision quantity once more with present vtp standing command. Will probably be reset and adjusted to zero.

PROCEDURE 2
RESET THE CONFIGURATION REVISION NUMBER USING VTP MODE:
The popular process to reset the VTP configuration revision quantity is by altering the area identify after which reverting again the configuration. Under is the step-by-step technique to be adopted –
This process is a quicker technique to clear the VTP configuration revision quantity. Right here we alter the swap VTP mode to “Clear Mode”, after which swap again. Under is the step-by-step technique to be adopted –
Step 1 –
Challenge present vtp standing command on Cisco Change with a view to examine the VTP configuration revision quantity.

Step 2 –
Go to the worldwide configuration mode and alter the VTP mode to ‘Clear’ on Cisco Change.
SW1#configure terminal
SW1(config)#vtp mode clear
Step 3 –
Once more change the VTP mode from ‘Clear’ to ‘Server’.
SW1(config)#vtp mode server
Step 4 –
Now examine the VTP configuration revision quantity once more with present vtp standing command. Will probably be reset and adjusted to zero.
