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
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. |
Packet | A set of information transmitted across a network. See also Frame. |
Participating A mode in which an L_Port in a loop has a valid AL_PA and can arbitrate, send
Modeframes, and retransmit received transmissions. See also L_Port, Non- participating Mode.
Path Selection The selection of a transmission path through the fabric.
Phantom | An AL_PA value that is assigned to an device that is not physically in the loop. |
Address | Also known as phantom AL_PA. |
Phantom | A device that is not physically in an arbitrated loop but is logically included |
Device | through the use of a phantom address. |
PLOGI | Port Login; the |
| with targets. See also FLOGI. |
| A Fibre Channel topology that employs direct links between each pair of |
| communicating entities. See also Topology. |
Port_Name
POST
Private
NL_Port
The unique identifier assigned to a Fibre Channel port. Communicated during login and port discovery.
Power On
An NL_Port that communicates only with other private NL_Ports in the same loop and does not log into the fabric.
