LIP	Loop initialization primitive. The signal that begins initialization
	in a loop. It indicates either loop failure or the resetting of
	a node.
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_PA values in an arbitrated loop. See also ???.
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 ???.
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.
LWL	Long wavelength. A type of fiber optic cabling that is based on
	1300 mm lasers and supports link speeds up to 2 Gb/s. May
	also refer to the type of transceiver. See also SWL.
master port	The port that determines the routing paths for all traffic flowing
	through a trunking group. One of the ports in the first ISL in the
	trunking group is designated as the master port for that group.
	See also ISL trunking.
MIB	Management Information Base. An SNMP structure to help
	with device management, providing configuration and device
	information. See also SNMP.
multicast	The transmission of data from a single source to multiple
	specified N_Ports (as opposed to all ports on the network).
N_Port	Node port. A port on a node that can connect to an FC port
	or to another N_Port in a point-to-point connection.
name server	A term frequently used to indicate a Simple Name Server
	(SNS). See also SNS.
NL_Port	Node loop port. A node port that has arbitrated loop
	capabilities. Used to connect an equipment port to the fabric
	in a loop configuration through an FL_Port. See also node.
node	An FC device that contains an N_Port or NL_Port.
