Fabric OS Procedures Guide

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.

The selection of a transmission path through the fabric.

An AL_PA value that is assigned to an device that is not physically in the loop.

Also known as phantom AL_PA.

A device that is not physically in an arbitrated loop but is logically included

through the use of a phantom address.

Port Login; the port-to-port login process by which initiators establish sessions

with targets. See also FLOGI.

A Fibre Channel topology that employs direct links between each pair of

communicating entities. See also Topology.

The unique identifier assigned to a Fibre Channel port. Communicated during

Power On Self-Test

series of tests run by a switch after it is turned on.

; a

An NL_Port that communicates only with other private NL_Ports in the same

loop and does not log into the fabric.
