K28.5
A special 10-bit character that indicates the beginning of a
transmission word that performs FC control and signaling
functions. The first seven bits are the common pattern.
kernel flash
Flash (temporary) memory connected to the peripheral bus of
the processor and visible within the processor’s memory space.
Also called a user flash.
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 is 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 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
With respect to FC, a physical connection between two ports,
consisting of both transmit and receive fibers.
link services
A protocol for link-related actions.
LIP
Loop initialization primitive. The signal that begins initialization
in a loop. It indicates either loop failure or the 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; loss of
synchronization for longer than the time-out value.
Loop_ID
A hexadecimal value representing one of the 127 possible
AL_PA values in an arbitrated loop. See also
.
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. See also
.
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. See also
