■ Select 4) to toggle the FC Port Mode.

— Auto Sense - Soft AL_PA: In this mode, the bridge FC port tries to

come up as a loop and if not successful then tries to come up as a

fabric. If the port comes up as a loop, it then determines whether it’s

on a private or public loop.

— N_Port: In this mode, the bridge’s FC port skips trying to come up as

a loop and instead tries coming up as a fabric only. If the bridge is on

a loop and N_Port mode is selected, an error in communication may

occur.

— Auto Sense - Hard AL_PA (default setting): In this mode, a unique

one-byte valid value (derived from an Arbitrated Loop Topology as

defined in ANSI specifications FC_AL ver 4.5) is used for the Fibre

Channel configuration. When configuring the Fibre Channel AL_PA,

the bridge presents a list of loop addresses along with the

corresponding AL_PA. From here, the user can select the loop address

desired.

■ Select 5) to change the ALPA Value: When Auto Sense - Hard AL_PA is

selected, you can set the Hard AL_PA value by entering a node number

from the AL_PA lookup table that appears when this option is selected.

This option only appears when the FC Port Mode is set to Auto Sense -

Hard AL_PA.
