■ 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. 88 Perform Configuration Chapter 4
