FCIP Issues
Listen Port is 3225
TCP parameters
SACK is disabled
PMTU discover is enabled, reset timeout is 3600 sec
Keep alive is 60 sec
Minimum retransmission timeout is 300 ms
Maximum number of re-transmissions is 4
Advertised window size is 64 KBThe following example shows a configuration error
when using multiple FCIP profiles on one physical Gigabit Ethernet port.
MDS2(config)#
fcip profile 21
MDS2(config-profile)#
ip address 10.10.11.2
error: fcip another profile exists with same port & ip
(Multiple FCIP profiles can be used on one physical Gigabit Ethernet port, but each profile must have a
different listening port.)
MDS2(config-profile)#
port 32
(Change the TCP listen port on the profile. The default is 3225.)
MDS2(config-profile)#
ip address 10.10.11.2
(The IP address for the Gigabit Ethernet port 2/1 is now accepted, and two FCIP profiles are using the
same Gigabit Ethernet port.)
MDS2(config-profile)#
end
MDS2#
show fcip profile 21
FCIP Profile 21
Internet Address is 10.10.11.2 (interface
GigabitEthernet2/1
)

(This is a new TCP listen port.)

Displaying Configuration Errors When Bringing Up a Tunnel on a Selected Port Using the CLI
The following example shows a configuration error when bringing a tunnel up on the selected port. This
could be either an FCIP profile issue or an FCIP interface issue. Both sides must be configured correctly.
MDS2(config)#
fcip profile 21
MDS2(config-profile)#
port 13
(Change the TCP listen port on switch MDS2.)
MDS2(config-profile)#
end
MDS2(config)#
interface fcip 21
MDS2(config-if)#
passive-mode
(Put interface fcip 21 in passive mode to guarantee MDS1 initiates a TCP connection.)
