Address and Device Mapping
A-3
Loop ID to AL_PA Mapping
During the Fibre Channel Arbitrated Loop (FC-AL) initialization process, a unique
Arbitrated Loop Physical Address (AL_PA) value is assigned to each port on the loop. Not
all of the 256 hex values are allowed as AL_PA values per FC-AL, so Loop IDs are used
to represent the 125 addresses that the router can use. You can assign a Loop ID to the
router. See

Table A-2 shows how a Loop ID value maps to an AL_PA. If you set the Loop ID to SOFT,
the router attempts to obtain an available Loop ID, in the following order: 0, 1, 2, etc.
