Note
(Note 1) "D&A" refers to the Domain and Area; "Local" means the Domain and Area on the Local
Loop, "Remote" means the Domain and Area of the Remote Loop.
(Note 2) The behavior of an FL_Port when it receives a unicast frame from a Local NL_Port destined for
another Local NL_Port is not defined by this report.
(Note 3) After NL_Port login is successful, the transmitted frame uses S_ID which has returned from PLOGI
ACC of D_ID.
The S_ID and D_ID are created by the sender of the frame, and the sender
performs an OPN on the source loop. The FL_Port performs the OPN on the
destination loop; this OPN is received by the frame recipient. If both source and
destination are on the same Local Loop, the OPN shall be performed by the frame
sender only.
