What is rldot1sMstpInstancePortDesignatedPort?

This read-only 2-byte OCTET STRING is the Port Identifier of the port on the segment's Designated Bridge for this port's connection. An admin inspects it to identify exactly which port on the neighboring designated switch is responsible for this segment. For example, decoding this value would let an admin trace which specific uplink port on the core switch is forwarding for the segment attached to this local port.
