Chapter 28 Configuring FICON
FICON Port Numbering
You can use the default port numbers if they are available (see
Table 28-1 on page 28-9
) or if you reserve
port numbers from the pool of port numbers that are not reserved for Fibre Channel interfaces (see
the
“About the Reserved FICON Port Numbering Scheme” section on page 28-10
).
To find the first available port number to bind an FCIP or PortChannel interface, use the
show ficon
first-available port-number
command (see
Example 28-12 on page 28-43
).
Tip
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
Example 28-13 on page 28-43
).
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:
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 .
Command
Purpose
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.
Note
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” section on page 28-23
.
Step 4
switch(config)#
no ficon logical-port
assign port-numbers 230-249
Releases the port numbers.
Note
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” section on
page 28-23
