Configuring FCIP ports for a single ISL on Cisco 9250i FC switches

You must configure the FCIP switch ports that connect the ISL (E-ports) by creating FCIP profiles and interfaces, and then assigning them to the IPStorage1/1 GbE interface.

This task is only for configurations using a single ISL per switch fabric, using the IPStorage1/1 interface on each switch.

This task must be performed on each FC switch.

Two FCIP profiles are created on each switch:

  • Fabric 1

    • FC_switch_A_1 is configured with FCIP profiles 11 and 111.

    • FC_switch_B_1 is configured with FCIP profiles 12 and 121.

  • Fabric 2

    • FC_switch_A_2 is configured with FCIP profiles 13 and 131.

    • FC_switch_B_2 is configured with FCIP profiles 14 and 141.

  1. Enter configuration mode: config t
  2. Enable FCIP: feature fcip
  3. Configure the IPStorage1/1 GbE interface:
    1. Enter configuration mode: conf t
    2. Specify the IPStorage1/1 interface: interface IPStorage1/1
    3. Specify the IP address and subnet mask: interface ip-address subnet-mask
    4. Specify the MTU size of 2500 : switchport mtu 2500
    5. Enable the port: no shutdown
    6. Exit configuration mode: exit

    The following example shows the configuration of an IPStorage1/1 port:
    conf t
    interface IPStorage1/1
      ip address 192.168.1.201 255.255.255.0
      switchport mtu 2500    
      no shutdown
    exit
  4. Configure the FCIP profile for FC-VI traffic:
    1. Configure an FCIP profile and enter FCIP profile configuration mode: fcip profile FCIP-profile-name

      The profile name depends on which switch is being configured.
    2. Assign the IP address of the IPStorage1/1 interface to the FCIP profile: ip address ip-address
    3. Assign the FCIP profile to TCP port 3227 : port 3227
    4. Set the TCP settings: tcp keepalive-timeout 1 tcp max-retransmissions 3 max-bandwidth-mbps 5000 min-available-bandwidth-mbps 4500 round-trip-time-ms 3 tcp min-retransmit-time 200 tcp keepalive-timeout 1 tcp pmtu-enable reset-timeout 3600 tcp sack-enable no tcp cwm

    The following example shows the configuration of the FCIP profile:
    conf t
    fcip profile 11
      ip address 192.168.1.333 
      port 3227
      tcp keepalive-timeout 1
    tcp max-retransmissions 3 
    max-bandwidth-mbps 5000 min-available-bandwidth-mbps 4500 round-trip-time-ms 3
      tcp min-retransmit-time 200
      tcp keepalive-timeout 1
      tcp pmtu-enable reset-timeout 3600 
      tcp sack-enable
      no tcp cwm
  5. Configure the FCIP profile for storage traffic:
    1. Configure an FCIP profile with the name 111 and enter FCIP profile configuration mode: fcip profile 111
    2. Assign the IP address of the IPStorage1/1 interface to the FCIP profile: ip address ip-address
    3. Assign the FCIP profile to TCP port 3229 : port 3229
    4. Set the TCP settings: tcp keepalive-timeout 1 tcp max-retransmissions 3 max-bandwidth-mbps 5000 min-available-bandwidth-mbps 4500 round-trip-time-ms 3 tcp min-retransmit-time 200 tcp keepalive-timeout 1 tcp pmtu-enable reset-timeout 3600 tcp sack-enable no tcp cwm

    The following example shows the configuration of the FCIP profile:
    conf t
    fcip profile 111
      ip address 192.168.1.334 
      port 3229
      tcp keepalive-timeout 1
    tcp max-retransmissions 3 
    max-bandwidth-mbps 5000 min-available-bandwidth-mbps 4500 round-trip-time-ms 3
      tcp min-retransmit-time 200
      tcp keepalive-timeout 1
      tcp pmtu-enable reset-timeout 3600 
      tcp sack-enable
      no tcp cwm
  6. Create the first of two FCIP interfaces: interface fcip 1

    This interface is used for FC-IV traffic.
    1. Select the profile 11 created previously: use-profile 11
    2. Set the IP address and port of the IPStorage1/1 port on the partner switch: peer-info ipaddr partner-switch-port-ip port 3227
    3. Select TCP connection 2 : tcp-connection 2
    4. Disable compression: no ip-compression
    5. Enable the interface: no shutdown
    6. Configure the control TCP connection to 48 and the data connection to 26 to mark all packets on that differentiated services code point (DSCP) value: qos control 48 data 26
    7. Exit the interface configuration mode: exit

    The following example shows the configuration of the FCIP interface:
    interface fcip  1
      use-profile 11
    # the port # listed in this command is the port that the remote switch is listening on
     peer-info ipaddr 192.168.32.334   port 3227
      tcp-connection 2
      no ip-compression 
      no shutdown
      qos control 48 data 26
    exit
  7. Create the second of two FCIP interfaces: interface fcip 2

    This interface is used for storage traffic.
    1. Select the profile 111 created previously: use-profile 111
    2. Set the IP address and port of the IPStorage1/1 port on the partner switch: peer-info ipaddr partner-switch-port-ip port 3229
    3. Select TCP connection 2 : tcp-connection 5
    4. Disable compression: no ip-compression
    5. Enable the interface: no shutdown
    6. Configure the control TCP connection to 48 and data connection to 26 to mark all packets on that differentiated services code point (DSCP) value: qos control 48 data 26
    7. Exit the interface configuration mode: exit

    The following example shows the configuration of the FCIP interface:
    interface fcip  2
      use-profile 11
    # the port # listed in this command is the port that the remote switch is listening on
     peer-info ipaddr 192.168.32.33e  port 3229
      tcp-connection 5
      no ip-compression 
      no shutdown
      qos control 48 data 26
    exit
  8. Configure the switchport settings on the fcip 1 interface:
    1. Enter configuration mode: config t
    2. Specify the port you are configuring: interface fcip 1
    3. Shut down the port: shutdown
    4. Set the port to E mode: switchport mode E
    5. Enable the trunk mode for the port: switchport trunk mode on
    6. Set the trunk allowed vsan to 10 : switchport trunk allowed vsan 10
    7. Set the speed for the port: switchport speed speed
  9. Configure the switchport settings on the fcip 2 interface:
    1. Enter configuration mode: config t
    2. Specify the port you are configuring: interface fcip 2
    3. Shut down the port: shutdown
    4. Set the port to E mode: switchport mode E
    5. Enable the trunk mode for the port: switchport trunk mode on
    6. Set the trunk allowed vsan to 20 : switchport trunk allowed vsan 20
    7. Set the speed for the port: switchport speed speed
  10. Repeat the previous steps on the second switch.

    The only differences are the appropriate IP addresses and unique FCIP profile names.

    • When configuring the first switch fabric, FC_switch_B_1 is configured with FCIP profiles 12 and 121.

    • When configuring the first switch fabric, FC_switch_A_2 is configured with FCIP profiles 13 and 131 and FC_switch_B_2 is configured with FCIP profiles 14 and 141.

  11. Restart the ports on both switches: no shutdown
  12. Exit the interface configuration on both switches: end
  13. Copy the updated configuration to the startup configuration on both switches: copy running-config startup-config 

    FC_switch_A_1(config-if)# end
    FC_switch_A_1# copy running-config startup-config
     
    FC_switch_B_1(config-if)# end
    FC_switch_B_1# copy running-config startup-config
  14. Repeat the previous steps on the second switch fabric.
