Auto Sense or N_Port:
Auto Sense: In this mode, the Fibre Channel port tries to negotiate as a
loop. If it is not successful, then the Fibre Channel 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. Use this setting if a Compaq
switch is being used. If the router is on a loop and N_Port mode is
selected, an error in communication may occur.
