Link Status indicates the port link status.
Port Mode (default: N_Port) sets the port mode.
Port Mode settings:
— Auto Sense In this mode, the FC port tries to negotiate as a loop. If it is
not successful, then the FC port negotiates as a fabric. If the port comes
up as a loop, it then determines whether it is on a private or public loop.
— N_Port (default) This mode allows the router to bypass the loop
negotiation and come up as a fabric only. If the router is on a loop, and
N_Port mode is selected, an error in communication may occur.
Use Hard AL_PA enables or disables Hard AL_PA usage.
Hard AL_PA Settings When Hard AL_PA usage is enabled, select Set
AL_PA Settings to display the AL_PA Lookup Table.
Use the table to find the node number. This unique one-byte valid value
(derived from an Arbitrated Loop Topology defined in ANSI specification
FC_AL version 4.5) is used for the FC configuration (see
Visual Manager User Interface
Figure 44).
