Glossary Isolated E_Port An E_Port that is online but not operational due to overlapping domain IDs or nonidentical parameters (such as E_D_TOVs). See also E_Port. IU Information Unit; a set of information as defined by either upper-level process protocol definition or upper-level protocol mapping. K28.5 A special 10-bit character used to indicate the beginning of a transmission word that performs Fibre Channel control and signaling functions. The first seven bits of the character are the comma pattern. See also Comma. L_Port 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 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, Participating Mode. Latency The period of time required to transmit a frame, from the time it is sent until it arrives. Link Services A protocol for link-related actions. Link As applies to Fibre Channel, a physical connection between two ports, consisting of both transmit and receive fibres. See also Circuit. LIP Loop Initialization Primitive; the signal used to begin initialization in a loop. Indicates either loop failure or resetting of a node. LIS_HOLD_TIME Loop Initialization Sequence Hold Time. The maximum period of time for a node to forward a loop initialization sequence. LM_TOV Loop Master Time-out Value; the minimum time that the loop master waits for a loop initialization sequence to return. Login BB_Credit The number of receive buffers a receiving L_Port has available when a circuit is first established. Communicated through PLOGI, PDISC link services, or FLOGI. 66 Quickloop Fabric Assist User Guide
