VTP - Revision Numbers on transparent switch

When using VTP, transparent switches will always have a VTP revision number of zero. Even if several VLANs are added and removed from such a switch, the revision number remains zero, as shown below:

SW1#show vtp status *Nov 9 06:38:55.759: %SYS-5-CONFIG_I: Configured from console by consoles VTP Version capable : 1 to 3 VTP version running : 2 VTP Domain Name : VTP Pruning Mode : Disabled VTP Traps Generation : Disabled Device ID : 5254.0006.8000 Configuration last modified by at 11-9-22 06:37:31 Feature VLAN: -------------- VTP Operating Mode : Transparent Maximum VLANs supported locally : 1005 Number of existing VLANs : 14 Configuration Revision : 0 MD5 digest : 0xD8 0x87 0x4A 0xF5 0x0D 0x70 0x90 0x91 0x65 0x54 0x4B 0x9F 0x2A 0xC2 0x95 0xCC SW1#

This means that even local changes made do not change the revision number of the transparent switch, nor do any VTP messages that a transparent switch may receive and relay to other switches.

This makes sense, because a revision number has no meaning for a transparent switch from the moment that its VLAN configuration remains completely independent of any other switch on the network.
