Key A string of data (usually a numeric value) shared between two
entities and used to control a cryptographic algorithm. Usually
selected from a large pool of possible keys to make unauthorized
identification of the key difficult. See also 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 Public Key Cryptography.
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
nonparticipating mode. See also Nonparticipating Mode and
Participating Mode.
LAN Local area network. A network in which transmissions typically take
place over fewer than 5 kilometers (3.4 miles).
The period of time required to transmit a frame, from the time it is
sent until it arrives.
LED Light-emitting diode. Used to indicate status of elements on switch.
LIFA Loop-initialization fabric-assigned frame. 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 final frame transmitted
in a loop initialization process. A returned LIRP contains an
accumulation of all of the AL_PA position maps. This allows loop
members to determine their relative loop position. This is an optional
frame and is not transmitted unless the LIRP is also transmitted.
