254 Glossary
latency
The time required to transmit a frame. Together, latency and bandwidth define the speed and capacity of a link or
system.
LED
Light-emitting diode. Indicates the status of elements on a 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. LILP is an optional frame and is not transmitted unless the LIRP is also transmitted.
Link Services
A protocol for link-related actions.
LIP
Loop initialization primitive. The signal that begins initialization in a loop. Indicates either loop failure or node
resetting.
LIPA
Loop-initialization previously assigned. The device marks a bit in the bitmap if it did not log in with the fabric in a
previous loop initialization.
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.
LISA
Loop-initialization soft-assigned frame. The fourth frame transmitted in the loop initialization process after a
temporary loop master has been selected. L_Ports that have not selected an AL_PA in a LIFA, LIPA, or LIHA frame
select their AL_PA here.
LISM
Loop-initialization select master frame. The first frame transmitted in the initialization process when L_Ports select an
AL_PA. LISM is used to select a temporary loop master or the L_Port that subsequently starts transmission of the LIFA,
LIPA, LIHA, LISA, LIRP, or LILP frames.
LM_TOV
Loop master time-out value. The minimum time that the loop master waits for a loop initialization sequence to return.
