Port Identification By Index; Default Index/Area_Id Core Pid Assignment With No Port Swap - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Port identification by index

With the introduction of 48-port blades, indexing was introduced. Unique area IDs are possible up to 255
areas, but beyond that there needed to be some way to ensure uniqueness.
A number of fabric-wide databases supported by Fabric OS (including ZoneDB, the ACL DDC, and Admin
Domain) allow a port to be designated by the use of a D,P (domain,port) notation. Where the P
component appears to be the port number, but in up to 255 ports it is actually the area assigned to that
port.
If the PID format is changed from Extended-edge to Core, the P value for ports 0- 1 27 also changes. If two
ports are changed using the portSwap command, their respective areas and P values are exchanged.
For ports that are numbered above 255, the P value is actually a logical index. The first 256 ports continue
to have an index value equal to the area_ID assigned to the port. If a switch is using Core PID format, and
no port swapping has been done, the port Index value for all ports is the same as the physical port
numbers. Issuing a portswap command on a pair of ports exchanges those ports' area_ID and index
values.
NOTE: The portSwap command is not supported for ports above 256.
Table 63 shows the area ID and index mapping for core PID assignment. Note that up to 255 areas, the
area_ID mapping to the index is one-to-one. Beyond this, the index is similar but not exact, and in some
instances the area ID is shared among multiple ports.
This table provides the area_ID/Index assignment for the maximum number of ports (used by the FC4-48
and FC8-48 blades). If your blade does not have the maximum number of ports, use the lower sections of
the table to determine the area_ID and index.
