wfBrStpDesignatedRoot
Module: Wellfleet-SPAN-MIB
OID (symbolic): Wellfleet-SPAN-MIB::wfBrStpDesignatedRoot
OID (numeric): 1.3.6.1.4.1.18.3.5.1.2.1.8
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The bridge ID of the root of the spanning tree as determined by the Spanning Tree Protocol as executed by the bridge. This value is used as the Root Identifier parameter in all Configuration Bridge PDUs originated by this node. It is a 8-octet string. The first two octets make up the priority, and the last six are the MAC address of the designated root bridge.
What is wfBrStpDesignatedRoot?
Reports the Bridge ID of whichever switch the Spanning Tree Protocol has currently elected as the root bridge, as seen from this bridge; comparing this to wfBrStpBridgeID tells an admin whether this device is the root or is deferring to another switch.
