For a 3550:


Beginning in privileged EXEC mode, follow these steps to verify and reset the VTP configuration revision number on a switch before adding it to a VTP domain:


Command Purpose


Step 1


show vtp status


Check the VTP configuration revision number.


If the number is 0, add the switch to the VTP domain.


If the number is greater than 0, follow these steps:


a. Write down the domain name.


b. Write down the configuration revision number.


c. Continue with the next steps to reset the configuration revision number on the switch.


Step 2


configure terminal


Enter global configuration mode.


Step 3


vtp domain domain-name


Change the domain name from the original one displayed in Step 1 to a new name.


Step 4


end


The VLAN information on the switch is updated and the configuration revision number is reset to 0. You return to privileged EXEC mode.


Step 5


show vtp status


Verify that the configuration revision number has been reset to 0.


Step 6


configure terminal


Enter global configuration mode.


Step 7


vtp domain domain-name


Enter the original domain name on the switch.


Step 8


end


The VLAN information on the switch is updated, and you return to privileged EXEC mode.


Step 9


show vtp status


(Optional) Verify that the domain name is the same as in Step 1 and that the configuration revision number is 0.

Just set the vtp domain name to a name that is not what you are using currently and then change it back to what it should be and it should reset it to 0 . Use the show vtp commands to verify revision numbers.

another option is changing the vtp mode from it's originally to transparent mode and then back to server mode
