ieee8021QBridgeVlanVersionNumber
Module: IEEE8021-Q-BRIDGE-MIB
OID (symbolic): IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeVlanVersionNumber
OID (numeric): 1.3.111.2.802.1.1.4.1.1.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description:
The version number of IEEE 802.1Q that this device supports. Reported as 1 by VLAN Bridges that support only SST operation, and reported as 2 by VLAN Bridges that support MST operation.
What is ieee8021QBridgeVlanVersionNumber?
This OID holds a version number (1 for single spanning tree, 2 for multiple spanning trees) indicating which VLAN bridging standard the device supports. It documents the device's redundancy capabilities. An operator checks this to confirm the device can support their desired network topology.
