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.
One of two possible modes for an L_Port, in which the L_Port is in an
arbitrated loop, using loop protocol. An L_Port in Loop Mode can
also be in Participating Mode or Nonparticipating Mode.
Looplet A set of devices connected in a loop to a port that is a member of
another loop.
LPB Loop port bypass. A primitive sequence transmitted by an L_Port to
bypass one or all L_Ports to which it is directed. It is used only in
arbitrated loops.
LPE Loop port enable. A primitive sequence transmitted by an L_Port to
enable one or all L_Ports that have been bypassed with the LPB. It is
used only in arbitrated loops.
LPSM Loop Port State Machine. Logic that monitors and performs the tasks
required for initialization and access to the loop. It is maintained by
an L_Port to track behavior through different phases of loop
operations. Alternatively, the logical entity that performs
arbitrated-loop protocols and defines the behavior of L_Ports when
they require access to an arbitrated loop.
LR Link reset. A primitive sequence used during link initialization
between two N_Ports in point-to-point topology or an N_Port and an
F_Port in fabric topology. The expected response is an LRR.
LRR Link reset response. A primitive sequence during link initialization
between two N_Ports in point-to-point topology or an N_Port and an
F_Port in fabric topology. It is sent in response to an LR and expects a
response of Idle.
LWL Long wavelength. A type of fiber-optic cabling that is based on
1300 mm lasers and supports link speeds of 1.0625 Gb/s and
2.125 Gb/s. May also refer to the type of GBIC or SFP. See also SWL.
M
Memory allocation. Usually relates to buffer credits.
MAN Metropolitan area network.
