K28.5 A special 10-bit character that indicates the beginning of a
transmission word that performs FC control and signaling
functions. The fi rst seven bits are the common pattern.
kernel fl ash Flash (temporary) memory connected to the peripheral bus of
the processor and visible within the processor’s memory space.
Also called a user fl ash .
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 .
See also non-participating mode .
latency The time required to transmit a frame from the time it is sent
until it arrives. Together, latency and bandwidth de fi ne 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 fi bers.
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 AL_PA .
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 AL_PA .
LPSM Loop port state machine. The logical entity that performs
arbitrated loop protocols and de fi nes the behavior of L_Ports
when they require access to an arbitrated loop. See also L_Port .
