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 fi rst ISL in the
trunking group is designated as the master port for that group.
See also ISL trunking.
MIB Management I nformation B ase. 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

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 por t. 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.
non-participating
mode
A mode in which an L_Port in a loop is inactive and cannot
arbitrate or send frames, but can retransmit any received
transmissions. This mode is entered if there are m ore than 127
devices in a loop and an AL_PA cannot be acquired. See also
L_Port, AL_PA.

Onboard Admin-
istrator (OA)
The HP BladeSystem On boa rd Administrator (OA) is the
enclosure management processor, subsystem, and firmware
base used to support the HP BladeSystem c7000 or HP
BladeSystem c3000 and all the m ana ged devices contained
within the enclosure.
packet A set of information transmitted across a network.
participating
mode
A mode in which an L_Port in a loop has a valid AL_PA
and can
arbitrate, send frames, and retransmit received transmissions.
path selection The selection of a transmission path through the fabric. HP
switches use the FSPF protocol for transmission pa th selection.
