K28.5 A special 10-bit character that indicates 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.
See also comma.
key A string of data (usually a numeric value) shared between two entities and used
to control a cryptographic algorithm.

key pair In public key cryptography, a pair of keys consisting of an entity's public and
private key. The public key can be publicized, but the private key must be kept
secret.
See also
LAN Local area network. A network in which transmissions typically take place over
fewer than 5 kilometers (3.4 miles).
See also
latency The time required to transmit a frame. Together, latency and bandwidth define
the speed and capacity of a link or system.
leaf class In SMI, a class that has no subclasses.
See also SMI.
LED Light-emitting diode. A device used to indicate the status of elements on a switch.
LIFA Loop-initialization fabric-assigned frame. A frame that contains a bitmap of all
fabric-assigned AL_PAs and is the first frame transmitted in the loop initialization
process after a temporary loop master has been selected.
LIHA Loop-initialization hard-assigned frame. A hard-assigned AL_PA that is indicated
by a bit set and is the third frame transmitted in the loop initialization process
after a temporary loop master has been selected.
LILP Loop-initialization loop-position frame. The last frame transmitted in a loop
initialization process after all L_Ports have selected an AL_PA. This frame is
transmitted around the Loop so that all L_Ports can determine the relative position
of all other L_Ports around the Loop. L_Port support for this frame is optional,
and this frame is not transmitted unless the LIRP is also transmitted.
See also LIRP.
link control facility A link hardware facility that attaches to an end of a link and manages
transmission and reception of data. It handles the physical and logical control
of the Fibre Channel link for each mode.
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 node resetting.
LIPA Loop-initialization previously assigned frame. The second frame transmitted in
the loop initialization process after a temporary Loop master has been selected.
L_Ports that had an AL_PA prior to the loop initialization will select their AL_PA's
in this frame as it makes its way around the loop.
LIRP Loop-initialization report position frame. The first frame transmitted in the loop
initialization process after all L_Ports have selected an AL_PA.The LIRP gets
transmitted around the loop so all L_Ports can report their relative physical
position. This is an optional frame.
See also LILP.
