Abstract
A method and apparatus for detection of a port name in a loop network is provided, particularly a loop network in the form of a Fibre Channel Arbitrated Loop (FC-AL). The loop network () has a plurality of devices () each device () having at least one port () on the loop network (). The method includes determining which ports () are populated with devices () for which the unique port name (WWPN) is not known. The populated ports are then all bypassed and a mode is entered on the loop network () in which idle frames are transmitted around the loop network (). One port is un-bypassed at a time and the port name from the un-bypassed port is received and recorded. The port name is received from the un-bypassed port in a Loop Initialisation Select Master (LISM) frame transmitted by the un-bypassed port.
