bdgPortDesigBrdg
Module: CTRON-BDG-MIB
OID (symbolic): CTRON-BDG-MIB::bdgPortDesigBrdg
OID (numeric): 1.3.6.1.4.1.52.1.3.1.2.21
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The network address of the bridge that is assumed to be the root bridge on the network.
What is bdgPortDesigBrdg?
This read-only octet string identifies the network address of the bridge that this port's segment currently believes is the root bridge. An admin compares this per-port value against the device-wide bdgdeviceDesigRoot to confirm all ports agree on the same root, since a mismatch could indicate a spanning tree inconsistency. For example, if bdgPortDesigBrdg for port 2 shows a different bridge identifier than bdgdeviceDesigRoot, the admin would investigate a potential spanning tree misconfiguration on that segment.
