Caution: If this configuration setting is incorrectly set, processing difficulties
may occur. Before changing this setting, evaluate the need for the change and
verify the desired setting. HP recommends backing up the router configuration
to an external file before making changes to this setting.
Port Mode (default: N_Port) sets the port mode.
Port Mode settings:
— 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. 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 displays 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 Fibre Channel configuration
(see Figure 23).
