Fibre-optic cabling specification allowing up to 500 m between devices.
Node Port. Port that can attach to a fibre channel port. See also NL_Port,
Nx_Port.
Network Address Authority. An identifier that indicates the format of a
network address.
Service of storing names, addresses, and attributes for up to 15 minutes,
provided by a switch to other entities in fabric. Defined by fibre channel
standards, and existing at a well-known address. Also called Simple Name
Server, SNS, or directory service. See also FS.
Node Loop Port. An N_Port that can use loop protocol. See also N_Port,
Nx_Port.
Fibre channel entity with one or more N_Ports or NL_Ports.
Unique identifier for a node, communicated during login and port discovery.
Mode in which L_Port is inactive in loop and cannot arbitrate or send frames,
but can retransmit received transmissions. Port enters mode if there are more
than 127 devices in loop, and an AL_PA cannot be acquired. See also
Participating mode.
Node port that can operate as either an N_Port or NL_Port.
The L_Port that wins arbitration in an arbitrated loop and sends an OPN
ordered set to the destination port, then enters the open state.
The L_Port that receives the OPN ordered set from the open originator, and
then enters the open state.
The state in which a port can establish a circuit with another port. A port must
be in the open state before it can arbitrate.
Open Primitive Signal. The protocol used by a port that has won arbitration
in an arbitrated loop to establish a circuit.
A type of transmission word that occurs outside of frames, and is used to
manage frame transport and differentiate fibre channel control information
from data. See also Data word, Transmission word.
