ctPvstStpPortDesignatedBridge
Module: CTRON-BRIDGE-MIB
OID (symbolic): CTRON-BRIDGE-MIB::ctPvstStpPortDesignatedBridge
OID (numeric): 1.3.6.1.4.1.52.4.1.2.3.2.2.6.1.9
Node type: OBJECT-TYPE
Type: BridgeId
Access: read-only
Description: The Bridge Identifier of the bridge which this port considers to be the Designated Bridge for this port's segment.
What is ctPvstStpPortDesignatedBridge?
This read-only BridgeId identifies which bridge this port considers to be the Designated Bridge responsible for forwarding traffic onto the LAN segment it connects to, for this VLAN's spanning tree. An administrator checks this to confirm which neighboring device is actually controlling traffic on a shared segment, useful when diagnosing unexpected forwarding behavior between two interconnected switches. For example, on a segment shared by two switches, the admin reads this value to confirm the intended core switch, not the edge switch, is winning the designated bridge role for the relevant VLAN.
