The default FICON port number is assigned based on the front panel location of the port and is specific
to the slot in which the module resides. Thirty-two (32) port numbers are assigned to each slot on all
Cisco MDS 9000 Family switches except for the Cisco MDS 9513 Director, which has 16 port numbers
assigned for each slot. These default numbers are assigned regardless of the module's physical presence
in the chassis, the port status (up or down), or the number of ports on the module (4, 12, 16, 24, or 48).
If a module has fewer ports than the number of port numbers assigned to the slot, then the excess port
numbers are unused. If a module has more ports than the number of port numbers assigned to the slot,
the excess ports cannot be used for FICON traffic unless you manually assign the port numbers.
Note Follow the steps in
excess ports by manually assigning more port numbers to the slot. Before doing this, however, we
recommend that you review the default port number assignments for Cisco MDS 9000 switches shown
in Table 36-3 on page
of FICON port numbering:

Note Only Fibre Channel, PortChannel, and FCIP ports are mapped to FICON port numbers. Other types of
interfaces do not have a corresponding port number.
