Multimode N_Port Name server NL_Port Node Node name Nonparticipating mode Nx_Port Ordered set Participating mode Phantom device Phantom address PLOGI Point-to-point Port_Name Fibre-optic cabling specification allowing up to 500 meters between devices. Node Port. Port that can attach to a fibre channel port. See also NL_Port, Nx_Port. Service of storing names, addresses, and attributes for up to 15 minutes, provided by a switch to other entities in fabric. Defined by fibre channel standards, and existing at a well-known address. Also called Simple Name Server, SNS, or directory service. See also FS. Node Loop Port. An N_Port that can use loop protocol. See also N_Port, Nx_Port. Fibre channel entity with one or more N_Ports or NL_Ports. Unique identifier for a node, communicated during login and port discovery. Mode in which L_Port is inactive in loop and cannot arbitrate or send frames, but can retransmit received transmissions. Port enters mode if there are more than 127 devices in loop, and an AL_PA cannot be acquired. See also Participating mode. Node port that can operate as either an N_Port or NL_Port. A type of transmission word that occurs outside of frames, and is used to manage frame transport and differentiate fibre channel control information from data. See also Data word, Transmission word. Mode in which an L_Port in a loop has valid AL_PA and can arbitrate, send frames, and retransmit received transmissions. See also Nonparticipating mode. Device not physically in a loop but logically included by phantom address. AL_PA value assigned to device not physically in loop. Also called phantom AL_PA. Port Login. Port-to-port login process by which initiators establish sessions with targets. See also FLOGI. Two fibre channel devices connected by a direct link. See also Topology. Unique FC identifier for port, communicated during login and port discovery. 48 QuickLoop User's Guide
