Port Addresses

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

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.
Note
FICON port numbers are not changed for ports that are active. You must first disable the interfaces using the
shutdown command.
Note
You can configure port numbers even when no module is installed in the slot.
