Glossary 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. Together, latency and bandwidth define the speed and capacity of a link or system. LED Light Emitting Diode. Used on HP switches to indicate the status of various switch elements. 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 fibers. 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. See also BB_Credit. Loop Circuit A temporary bidirectional communication path established between L_Ports. Fabric Watch Version 3.1.x/4.1.x User Guide 253
