Configuring FCIP

Peer IP Address
The basic FCIP configuration uses the peer's IP address to configure the peer information. You can also
specify the peer's port number to configure the peer information. If you do not specify a port, the default
3225 port number is used to establish connection.
To assign the peer information based on the IP address, port number, follow these steps:
Command
Step 1
switch(config-if)# peer-info ipaddr 10.1.1.1
switch(config-if)# no peer-info ipaddr
10.10.1.1
Step 2
switch(config-if)# peer-info ipaddr 10.1.1.1
port 3000
switch(config-if)# no peer-info ipaddr
10.1.1.1 port 2000
Step 3
switch(config-if)# no shutdown
Special Frames
You can alternatively establish an FCIP link with a peer using an optional protocol called special frames.
When special frames are enabled, the peer IP address (and optionally the port or the profile ID) only
needs to be configured on one end of the link. Once the connection is established, a special frame is
exchanged to discover and authenticate the link.
By default, the special frame feature is disabled. You must enable special frames my on the interfaces
on both peers to establish the FCIP link.
Refer to the Fibre Channel IP standards for further information on special frames.
Note
Special frame negotiation provides an additional authentication security mechanism because the link

validates the WWN of the peer switch.
To enable special frames, follow these steps:
Command
Step 1
switch(config-if)# special-frame peer-wwn
12:12:34:45:ab:bc:cd:00
switch(config-if)# no special-frame peer-wwn
12:12:34:45:ab:bc:cd:00

Advanced FCIP Interface Configuration
Purpose
Assigns an IP address to configure the peer
information. Because no port is specified, the
default port number, 3225, is used.
Deletes the assigned peer port information.
Assigns the IP address and sets the peer TCP
port to 3000. The valid port number range is
from 0 to 65535.
Deletes the assigned peer port information.
Enables the interface.
Purpose
Enables special frames and sets the peer WWN
as specified.
The peer WWN is the WWN of the peer
Note
switch. Use the show wwn switch
command to obtain the peer WWN.
Disables special frames (default).
