Abstract
This disclosure describes techniques that determine device connectivity in the absence of a network layer 2 discovery protocol such as Link Layer Discovery Protocol (LLDP). In one example, this disclosure describes a method that includes retrieving, from a bridge data store of a bridge device on a network having one or more host devices, a plurality of first interface indexes, wherein each first interface index corresponds to a network interface of network interfaces of the bridge device; retrieving, from the bridge data store, remote network addresses corresponding to the network interfaces of the bridge device, each remote network address of the remote network addresses corresponding to a second interface index; selecting a remote network address having a second interface index that matches the first interface index; determining a host device having the selected remote network address; and outputting an indication that the bridge device is coupled to the host device.
