What is sifDesigBridge?

This read-only OCTET STRING, though its source description is empty, holds the Bridge Identifier of the designated bridge for this port's network segment. An administrator reads it to identify which bridge, this one or a neighbor, is currently forwarding traffic for the shared segment attached to this port. For example, the admin reads sifDesigBridge and finds it doesn't match this chassis's own stBridgeId, confirming a neighboring switch is the designated bridge on that shared segment.
