Nonparticipating A mode in which an L_Port in a loop is inactive and cannot arbitrate

Mode 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 and Participating Mode.

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

O

Ordered Set 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.

P

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

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. See also L_Port and Nonparticipating Mode.

Path Selection The selection of a transmission path through the fabric. EMC 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 A device that is not physically in an arbitrated loop but is logically included through the use of a phantom address.

PLOGI Port Login; the port to port login process by which initiators establish sessions with targets. See also FLOGI.

Point to point A Fibre Channel topology that employs direct links between each pair of communicating entities. See also Topology.
