K28.5 kernel flash A special 10-bit character that indicates the beginning of a transmission word that performs FC control and signaling functions. The first seven bits are the common pattern. Flash (temporary) memory connected to the peripheral bus of the processor and visible within the processor's memory space. Also called a user flash. L_Port latency link link services LIP LM_TOV loop failure Loop_ID loop initialization LPSM LWL Loop port. A node port (NL_Port) or fabric port (FL_Port) that has arbitrated loop capabilities. An L_Port can be in one of two modes: • Fabric mode: Connected to a port that is not loop capable and is using fabric protocol. • Loop mode: In an arbitrated loop and using loop protocol. An L_Port in loop mode can also be in participating mode or non-participating mode. See also non-participating mode. The time required to transmit a frame from the time it is sent until it arrives. Together, latency and bandwidth define the speed and capacity of a link or system. With respect to FC, a physical connection between two ports, consisting of both transmit and receive fibers. A protocol for link-related actions. Loop initialization primitive. The signal that begins initialization in a loop. It indicates either loop failure or the resetting of a node. Loop master time-out value. The minimum time that the loop master waits for a loop initialization sequence to return. Loss of signal within a loop for any period of time; loss of synchronization for longer than the time-out value. A hexadecimal value representing one of the 127 possible AL_PA values in an arbitrated loop. See also AL_PA. The logical procedure used by an L_Port to discover its environment. Can be used to assign AL_PA addresses, detect loop failure, or reset a node. See also AL_PA. Loop port state machine. The logical entity that performs arbitrated loop protocols and defines the behavior of L_Ports when they require access to an arbitrated loop. See also L_Port. Long wavelength. A type of fiber optic cabling that is based on 1300 mm lasers and supports link speeds up to 2 Gb/s. May also refer to the type of transceiver. See also SWL. master port MIB The port that determines the routing paths for all traffic flowing through a trunking group. One of the ports in the first ISL in the trunking group is designated as the master port for that group. See also ISL trunking. Management Information Base. An SNMP structure to help with device management, providing configuration and device information. See also SNMP. 58 Glossary
