are not reserved for Fibre Channel interfaces (see the About the Reserved FICON Port Numbering Scheme,
on page 255).
To find the first available port number to bind an FCIP or PortChannel interface, use the show ficon
first-available port-number command (see Displays the Available Port Numbers, on page 291).
The show ficon vsan portaddress brief command displays the port number to interface mapping. You can
assign port numbers in the PortChannel/FCIP range that are not already assigned to a PortChannel or FCIP
interface (see Displays Port Address Information in a Brief Format, on page 291).
Tip
Reserving FICON Port Numbers for FCIP and PortChannel Interfaces
You must reserve port numbers for logical interfaces, such as FCIP and PortChannels, if you plan to use them.
To reserve FICON port numbers for logical interfaces, follow these steps:
Step 1 switch# config t
switch(config)#
Enters configuration mode.
Step 2 switch(config)# ficon logical-port assign port-numbers 230-249
Reserves port numbers 230 through 249 for FCIP and PortChannel interfaces.
Step 3 switch(config)# ficon logical-port assign port-numbers 0xe6-0xf9
Reserves port numbers 0xe6 through 0xf9 for FCIP and PortChannel interfaces.
You cannot change port numbers that are active. You must disable the interfaces using the shutdown command
and unbind port numbers using the no ficon portnumber command. See the Configuring FICON Ports, on
page 269.
Note
Step 4 switch(config)# no ficon logical-port assign port-numbers 230-249
Releases the port numbers.
You cannot release port numbers for interfaces that are active.You must disable the interfaces using the shutdown
command and unbind port numbers using the no ficon portnumber command. See the Configuring FICON
Ports, on page 269.
Note
FC ID Allocation
FICON requires a predictable and static FC ID allocation scheme. When FICON is enabled, the FC ID allocated
to a device is based on the port address of the port to which it is attached. The port address forms the middle
byte of the fabric address. Additionally, the last byte of the fabric address should be the same for all devices
in the fabric. By default, the last byte value is 0 and can be configured.
