ABSTRACT:
An enterprise network includes at least one communication device208-1, an Open Systems Interconnect (OSI) Layer 2 switch206, and a corresponding enterprise switch208. The communication device208-1is connected to at least one of an access point904-1and a respective port207-1of the Layer 2 switch206. The enterprise network includes a plurality of Emergency Location Information Numbers (ELINs) corresponding to differing segments of the enterprise network. The Layer 2 switch206serves at least one of the differing segments. The communication device208-1includes a discovery agent252operable, when a predetermined first event occurs, to obtain from the Layer 2 switch206at least one of an access point identifier, a switch identifier from the Layer 2 switch206, and a port identifier identifying the respective port207-1.
