Instruction Manual

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 p aths for all trafﬁc ﬂowing

through a trunking group. One of the ports in the ﬁrst ISL in the

trunking group is designated as the m aster port for that group.

See also ISL trunking.

MIB Management Information Base. An SNMP structure to help

with device management, providing conﬁguration and d evice

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 net work).

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 Nam e 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_Por t.

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 more than 127

devices in a loop and an AL_PA cannot be acquired. See also

L_Port, AL_PA.

Nx_Port AnodeportthatcanoperateasanN_PortorNL_Port.

Onboard Admin-

istrator (OA)

The HP BladeSystem Onboard Administrator (OA) is the

enclos ure management processor, subsystem, and ﬁrmware

base used to suppor t the HP BladeSystem c7000 or HP

BladeSystem c3000 and all the managed devices c ontained

within the enclosure.

packet A set of information tr ansmitted 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 retransm it received transmissions.

path selection The selection of a transm ission path through the fabric. HP

switches use the FSPF protocol for transmission path selection.
