Glossary
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.
Loop Failure
Loss of signal within a loop for any period of time, or loss of synchronization for longer than
the time-out value.
See also error.
