You can use the ficon slot assign port-numbers CLI command to use any excess ports by assigning
Note
numbers to the slots. Before you assign numbers to the slots however, we recommend that you review
the default port number assignments for Cisco MDS 9000 switches shown in
Only Fibre Channel, PortChannel, and FCIP ports are mapped to FICON port numbers. Other types of
Note
interfaces do not have corresponding port numbers.

Reserved FICON Port Numbering Scheme

A range of 250 port numbers are available for you to assign to all the ports on a switch.
that you can have more than 250 physical ports on a switch and the excess ports do not have port numbers
in the default numbering scheme. When you have more than 250 physical ports on your switch, you can
have ports without port number assigned if they are not in a FICON VSAN, or you can assign duplicate
port numbers if they are not used in the same FICON VSAN. For example, you can configure port
number 1 on interface fc1/1 in FICON VSAN 10 and fc10/1 in FICON VSAN 20.
A VSAN can have a maximum of 250 port numbers.
Note
FICON port numbers are not changed for ports that are active. You must first disable the interfaces using
Note
the shutdown CLI command.

250 through 253 The first 4, 12 or 16 port
and port 255 numbers are used for a 4-port,
12-port or 16-port model, and
the rest remain unused.
Extra ports on 24-port, 32-port,
and 48-port modules are not
allocated port numbers.
Supervisor modules are not
allocated port numbers.
The first 4 or 12 port numbers
