Abstract

A system monitors cable interface connections in a network. An individual cable interface connection includes a connection between a cable and an associated device in the network. The monitoring system includes a plurality of individual interface controllers for monitoring an associated plurality of individual cable interface connections. The plurality of individual interface controllers include a first interface controller for automatically, acquiring device type identification data from a second interface controller monitoring a connection between a cable and an associated device in the network. The device type identification data is acquired via the cable and the first and second cable interface connections at the ends of the cable. The device type identification data supports identification of the device associated with the second cable interface connection. The first interface controller further automatically compiles a map including data indicating devices in the network and associated device type identifiers.
