A hex value representing one of the 127 possible AL_PA values in an arbitrated loop.

A set of devices connected in a loop to a port that is a member of another loop.

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.

Long Wavelength; a type of fiber optic cabling that is based on 1300mm lasers and supports link speeds of 1.0625 Gbps. May also refer to the type of GBIC or SFP. See also SWL.

As relates to trunking, the port that determines the routing paths for all traffic flowing through the 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 Brocade ISL Trunking.

Management Information Base; an SNMP structure to help with device management, providing configuration and device information.

The transmission of data from a single source to multiple specified N_Ports (as opposed to all the ports on the network). See also Broadcast, Unicast.

A fiber optic cabling specification that allows up to 500 meters between devices.

Node Port; a port on a node that can connect to a fibre channel port or to another N_Port in a point-to-point connection. See also NL_Port, Nx_Port.

Frequently used to indicate Simple Name Server. See also SNS.

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 N_Port, Nx_Port.

A fibre channel device that contains an N_Port or NL_Port.

The unique identifier for a node, communicated during login and port discovery.

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, Participating Mode.

A node port that can operate as either an N_Port or NL_Port.

A transmission word that uses 8B/10B mapping and begins with the K28.5 character. Ordered sets occur outside of frames, and include the following items:

•Frame delimiters Mark frame boundaries and describe frame contents.

•Primitive signals Indicate events.

•Primitive sequences Indicate or initiate port states.

Ordered sets are used to differentiate fibre channel control information from data frames and to manage the transport of frames.

A set of information transmitted across a network. See also Frame.

A mode in which an L_Port in a loop has a valid AL_PA and can arbitrate, send frames, and retransmit received transmissions. See also L_Port, Non- participating Mode.
