ABSTRACT:
Element managers and processes retrieve information from a first packet switch. The information is derived from layer-two (data link layer) control packets relayed from a second packet switch to the first packet switch via a tunnel. The layer-two control packets conform to a layer-two control protocol. Based at least in part on the retrieved information, the element managers and processes determine that the tunnel is configured to relay layer-two control packets conforming to the layer-two control protocol despite a desired tunnel configuration specifying that the tunnel should not be configured to relay layer-two control packets conforming to the layer-two control protocol. Element managers and processes may alternatively or additionally detect other discrepancies between the desired tunnel configuration and the tunnel.
