vtpVersion
Module: CISCO-VTP-MIB
OID (symbolic): CISCO-VTP-MIB::vtpVersion
OID (numeric): 1.3.6.1.4.1.9.9.46.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The version of VTP in use on the local system. A device will report its version capability and not any particular version in use on the device. If the device does not support vtp, the version is none(3).
What is vtpVersion?
This read-only INTEGER reports which VTP (VLAN Trunking Protocol) version capability this device supports, being none(3) if the device does not support VTP at all. An administrator checks this to confirm whether a switch is even capable of participating in VTP, and which version, before troubleshooting VLAN propagation issues in a VTP domain. For example, a switch reporting vtpVersion as none(3) cannot be relied upon to propagate VLAN database updates via VTP the way a switch reporting one(1) or two(2) can.
