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.

node

A fibre channel 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 more than 127 devices in a loop and an AL_PA cannot be acquired.

Nx_Port

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

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.

phantom address

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

Also known as phantom AL_PA.

phantom device
