以下の構成を用いた MDS での FCIP の設定例になります。
先ず、FCIP で利用する GigabitEthernet interface に IP address を設定します。
MDS9222i-A(config)# interface gigabitethernet 1/1
MDS9222i-A(config-if)# ip add 192.168.1.1 255.255.255.0
MDS9222i-A(config-if)# no shutdown
MDS9222i-Aconfig-if)# exit --- 対向のMDSと別サブネットの場合は、static route を設定します MDS9222i-A(config)# ip route ?
A.B.C.D Destination prefix
MDS9222i-A(config)# ip route 192.168.2.0 ?
A.B.C.D Destination prefix mask
MDS9222i-A(config)# ip route 192.168.2.0 255.255.255.0 ?
A.B.C.D Configure the nexthop
interface Name of interface to use to get to destination network
MDS9222i-A(config)# ip route 192.168.2.0 255.255.255.0 192.168.1.254 ?
<CR>

MDS9222i-A(config)# ip route 192.168.2.0 255.255.255.0 192.168.1.254 interface ?

両方の MDS で設定したのち、ping を行い、round trip time を計測します。
ping が失敗するようであれば、"show interface" コマンドで link が上がっているか、"show ips ip route" コマンドで static route が正しく設定されているか確認します。
MDS9222i-A# ping 192.168.2.2

fcip を有効にした後、fcip profile、fcip interface を作ります。
MDS9222i-A(config)# feature fcip
MDS9222i-A(config)#
MDS9222i-A(config)# fcip profile 1
