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 memor y space.
Also called a user flash.
L_Port Loop port. A node port (NL_Por t) 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 m ode
or non-participating mode.
See also non-participating mode.
latency Thetimerequiredtotransmitaframefromthetimeitissent
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
anode.
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_PAvaluesinanarbitratedloop.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 defines the behavior of L_Ports
when they require access to an arbitrated loop. See also L_Port.
