the"About the Reserved FICON Port Numbering Scheme" section on page
To find the first available port number to bind an FCIP or PortChannel interface, use the show ficon
first-available port-number command (see
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

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:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# ficon logical-port assign
port-numbers 230-249
Step 3
switch(config)# ficon logical-port assign
port-numbers 0xe6-0xf9
Step 4
switch(config)# no ficon logical-port
assign port-numbers 230-249

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 .

Purpose
Enters configuration mode.
Reserves port numbers 230 through 249 for FCIP
and PortChannel interfaces.
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
