port to the fabric in a loop configuration through an FL_Port.
See also N_Port, Nx_Port.
Node Name
The unique identifier for a node, communicated during login and port discovery.
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.
See also L_Port, Participating Mode.
Nx_Port
A node port that can operate as either an N_Port or NL_Port.
Open Originator
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.
Open Recipient
The L_Port that receives the OPN ordered set from the open originator, and then enters the Open
state.
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.
OPN
