Page 203 highlights

By index With the introduction of 48-port blades, the Index 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, Secure FOS DDC policies, the ACL DDC, and Admin Domain) allow a port to be designated by the use of a "D,P" (Domain, Port) notation. While the "P" component appears to be the port number, in up to 255 ports it was actually the area assigned to that port. If the PID format is changed from Core to Extended-edge or vice-versa, the "P" value for ports 0-127 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 existing index-to-area_ID mapping for the first 256 ports in a switch is kept, and add values equal to the physical port number for the new FC4-48 ports. 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. Changing the PID format will change the index values as well as the area_ID values of the first 128 ports, and using portswap on a pair of ports will exchange those ports' area_ID and index values. Portswap is not supported for ports above 256. Table 52 and Table 53 show the area ID and index mapping for core and extended-edge 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. These tables provide the area_ID/Index assignment for the maximum number of ports (used by the FC4-48 blade). 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.

By index
With the introduction of 48-port blades, the Index 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, Secure FOS DDC policies,
the ACL DDC, and Admin Domain) allow a port to be designated by the use of a “D,P” (Domain, Port)
notation. While the “P” component appears to be the port number, in up to 255 ports it was actually the
area
assigned to that port.
If the PID format is changed from Core to Extended-edge or vice-versa, the “P” value for ports 0-127 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 existing
index-to-area_ID mapping for the first 256 ports in a switch is kept, and add values equal to the physical
port number for the new FC4-48 ports.
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. Changing the PID format will change the index values as well as the area_ID
values of the first 128 ports, and using portswap on a pair of ports will exchange those ports’ area_ID and
index values. Portswap is not supported for ports above 256.
Table 52
and
Table 53
show the area ID and index mapping for core and extended-edge 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.
These tables provide the area_ID/Index assignment for the maximum number of ports (used by the FC4-48
blade). 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.
