VTP revision number


The [VTP revision number](/vtp-revision-number) is a 32-bit used by [VTP](/vtp) to help synchronize the sharing of [VLAN](/vlan) information between participating switches.  The value can range from 0 to 4,294,967,296.

Practically speaking, a VTP implementation would never reach this number. If you make a change to your VLANs every second, resulting in the revision number being incremented every second, it would take over 1300 years to reach the maximum value of the revision number. So this is a practical impossibility unless there is some corruption in your VTP messages.
