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. latency The period of time required to transmit a frame, from the time it is sent until it arrives.

K
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.
kernel flash
Flash (temporary) memory connected to the peripheral bus of the processor, and visible
within the processor's memory space. Also known as “user flash”.
L
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.
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.
link
As applies to fibre channel, a physical connection between two ports, consisting of
both transmit and receive fibres.
link services
A 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.
LM_TOV
Loop master time-out value. The minimum time that the loop master waits for a loop
initialization sequence to return.
loop failure
Loss of signal within a loop for any period of time, or loss of synchronization for longer
than the time-out value.
loop initialization
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.
Loop_ID
A hex value representing one of the 127 possible AL_PA values in an arbitrated loop.
LPSM
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.
LWL
Long wavelength. A type of fiber optic cabling that is based on 1300mm lasers and
supports link speeds up to 2 Gbit/sec. May also refer to the type of transceiver.
