Set Up the Network Interfaces

1. For the Oracle Linux 6.x OS, switch off UEK, then reconnect the cables to the adapter.

   /boot/grub/menu.lst

2. Open the 70-persistent-net.rules file.

   /etc/udev/rules.d/70-persistent-net-rules

3. Record the name and addresses of each of the ports, and reboot the host.

   If you plan to make changes (for example, changing ethx port assignments), you should change them at this point. However, keeping the default settings provides the best results. Any changes will not be reflected until after a reboot or unless you shutdown all of the network interfaces by running the udevadm trigger.

4. In another terminal window, type the ifconfig -a command, and compare the ethx values.

   where ethx represents eth0, eth1, eth2, or ethn, according to the rules in the 70-persistent-net.rules file.

   If non-FCoE ports (for example, rje45) appear in the list, you can use the Network Settings GUI to determine which addresses are FCoE ports.

5. Configure LLDPad.
   1. For the SLES 11 SP2 OS, type these commands:

      # rclldpad start
      # service boot.lldpad start
      # service ipmi start
      # service ipmievd start
      # chkconfig ipmi on
      # chkconfig ipmievd on
      # chkconfig boot.lldpad on

   2. For all other Linux operating systems, type these commands:

      # service lldpad start
      # chkconfig lldpad on

6. For the SLES 11 SP2 OS, open the YaST-FCoE Client Configuration application, and complete these steps:
   1. On the Interfaces tab, ensure that the columns after the FCoE VLAN Interface are set to yes.
   2. On the Services tab, ensure that the FCoE VLAN Interfaces are set to when booting.
7. For each FCoE ethx port being configured, type the following commands, substituting x for the port number:

   # dcbtool sc ethx dcb on
   # dcbtool sc ethx app:0 e:1
   # dcbtool sc ethx pfc e:1 a:1 w:1

8. Create a configuration file for each FCoE port by repeating the following steps:
   1. Create a new cfg-ethx file for each port, where x represents the port number.

      # cp /etc/fcoe/cfg-ethx /etc/fcoe/cfg-ethx

      ---

      Note - The variable value of x should match the digit associated with the port in the names in the 70-persistent-net.rules file.

      ---

   2. Open each /etc/fcoe/cfg-ethx file, and add the following line to the top of the file:

      Onboot=”yes”

9. Start, and check the FCoE service.
   1. For the SLES 11 SP2 OS, execute these commands:

      # rcfcoe start
      # service boot.fcoe start
      # chkconfig boot.fcoe on
      # reboot

   2. For all other Linux operating systems, execute these commands:

      # service fcoe start
      # chkconfig fcoe on
      # reboot

10. Type the ifconfig -a, fcoeadm -i, and lsscsi commands to verify that FCoE is operational.
11. Open the Network Settings windows, and verify that the ethx values match the values that are in the /etc/udev/rules.d/70-persistent-net.rules file.

    If the values do not match, make the network settings match the values that are in the 70-persistent-net.rules file.

    If your TCP/IP connection into the Cisco or Brocade switch is through a VLAN trunk, you must create the VLAN at this point in the installation. The VLAN should have the IP address, netmask, and gateway of the port. The associated ethx port will not have an IP address. For instructions on how to create the VLAN, refer to these sites:
