By default, the special frame feature is disabled. You must enable special frames 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
Tip 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
Step 2
switch(config-if)# special-frame peer-wwn
12:12:34:45:ab:bc:cd:00 peer profile-id 155
switch(config-if)# no special-frame peer-wwn
12:12:34:45:ab:bc:cd:00 peer profile-id 155
Step 3
switch(config-if)# no shutdown

Active Connections

You can configure the required mode for initiating a TCP connection. By default, active mode is enabled
to actively attempt an IP connection. If you enable the passive mode, the switch does not initiate a TCP
connection rather waits for the peer to connect to it.
Note Ensure that both ends of the FCIP link are not configured as passive mode. If both ends are configured
as passive, the connection is not initiated.
To enable the passive mode, follow these steps:
Command
Step 1
switch(config-if)# passive-mode
switch(config-if)# no passive-mode
Step 2
switch(config-if)# no shutdown

Number of TCP Connections

You can specify the number of TCP connections from an FCIP link. By default, the switch tries two (2)
TCP connections for each FCIP link. You can configure one or two TCP connections. For example, the
Cisco PA-FC-1G Fibre Channel port adapter, which has only one (1) TCP connection, interoperates with

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).
Enables special frames and sets the peer WWN
and the profile ID (155).
Disables special frames (default).
Enables the interface.
Purpose
Enables passive mode while attempting a TCP connection.
Reverts to the factory set default of using the active mode
while attempting the TCP connection.
Enables the interface.
