Abstract: A method and apparatus for discovering and displaying a graphical representation of a plurality of network devices connected to a communication network comprises a control network module coupled to the plurality of network devices. A first component of a control network module captures attribute data from the network devices. A second component of the control network module constructs a switch data table identifying a media access control address for each port of a communication network switch associated with each of the plurality of network devices. The second component uses the attribute data and the switch data table to construct a neighbor data table for the plurality of network devices connected to the communication network. A third component of the control network module uses the neighbor data table to construct a neighboring device table and build the graphical representation of the communication network on a display device.
