适用范围：This part of ISO/IEC 14165 specifies signaling interface enhancements for FC-PH, to allowL_Ports to operate with an Arbitrated Loop topology. This standard defines L_Ports that retain thefunctionality of Ports as specified in FC-PH. The Arbitrated Loop topology attaches multiplecommunicating points in a loop without requiring switches.The Arbitrated Loop topology is a distributed topology where each L_Port includes the minimumnecessary function to establish a Loop circuit. A single FL_Port connected to an Arbitrated Loopallows multiple NL_Ports to attach to a Fabric.When an L_Port is operating on a Loop with at least one other L_Port, the L_Port uses theprotocol extensions to FC-PH that are specified in this standard.When an L_Port is connected with an N_Port or an F_Port, the L_Port communicates using theprotocol defined in FC-PH.Each L_Port may use a self-discovering procedure to find the correct operating mode without theneed for external controls.
