Link As applies to fibre channel, a physical connection between two ports,
consisting of both transmit and receive fibres. See also Circuit.
Link services Protocol for link-related actions.
LIP Loop Initialization Primitive. The signal used to begin initialization in a loop.
Indicates either loop failure or resetting of a node. See also Loop
initialization.
LIS_HOLD_TIME The maximum period of time for a node to forward a loop initialization
sequence.
LM_TOV Loop Master Timeout 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 service, or
FLOGI.
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 E_D_TOV.
Loop initialization Logical procedure used by L_Ports to discover environment. Can be used to
assign AL_PA addresses, detect loop failure, or reset a node. See also LIP.
Loop_ID Hex value representing one of 127 possible AL_PA values in a loop.
Looplet Set of devices connected in a loop to a port that is part of another loop.
LPSM Loop Port State Machine. Logical entity that performs arbitrated loop
protocols and defines behavior of L_Ports when they require access to
arbitrated loop.
LWL Long wavelength fibre optic cable. Based on 1300-nm lasers supporting
1.0625- Gbps link speeds. Connectors are color-coded blue. See also SWL.
MIB Management Information Base. SNMP structure that provides configuration
and device information to assist with device management.
Monitoring State The state in which a port is monitoring the flow of information for data
relevant to the port.
