Port Addresses

By default, port numbers are the same as port addresses. You can swap the port addresses (see the
Swapping" section on page
You can swap the port addresses by issuing the ficon swap portnumber command.

Implemented and Unimplemented Port Addresses

An implemented port refers to any port address that is assigned by default to a slot in the chassis (see

About the 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 a 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.
Note A VSAN can have a maximum of 250 port numbers.
