ctPvstStpPortDesignatedRoot
Module: CTRON-BRIDGE-MIB
OID (symbolic): CTRON-BRIDGE-MIB::ctPvstStpPortDesignatedRoot
OID (numeric): 1.3.6.1.4.1.52.4.1.2.3.2.2.6.1.7
Node type: OBJECT-TYPE
Type: BridgeId
Access: read-only
Description: The unique Bridge Identifier of the Bridge recorded as the Root in the Configuration BPDUs transmitted by the Designated Bridge for the segment to which the port is attached.
What is ctPvstStpPortDesignatedRoot?
This read-only BridgeId reports the Bridge Identifier of the root bridge as recorded in the Configuration BPDUs transmitted by the Designated Bridge for the LAN segment attached to this port, within this VLAN's spanning tree. An administrator compares this value against the locally known root ID to confirm that the segment this port connects to agrees on which bridge is root for the VLAN. For example, if this designated-root value differs from what the local bridge itself considers root, the admin suspects a partitioned or misconverged spanning tree on that segment.
