Configuring FCoE for the MZ522 in RHEL

To configure FCoE in RHEL 7.2, perform the following steps:

1. If NPAR is enabled, set the working mode of the PFs that need to use the FCoE function to FCoE (NIC+FCoE). For details, see Configuring NPAR. After the configuration, check and record the NIC MAC address of the PF in NIC+FCoE mode.

   If NPAR is disabled, skip this step.

2. Install the Ethernet driver and the FCoE driver in RHEL 7.2. For details, see Installing and Uninstalling the MZ522 Drivers in Linux.
3. Enable automatic start of lldpad and fcoe services upon server startup.

   # chkconfig lldpad on 
   # chkconfig fcoe on

4. Upload FCoE drivers.

   # modprobe bnx2x 
   # modprobe cnic 
   # modprobe bnx2fc

5. Create the file /etc/fcoe /cfg-<nic_port_name> and write FCoE configurations into the file. nic_port_name in the file name indicates the name of the NIC port (or example, enp133s0f0) with FCoE enabled. If NPAR is enabled, nic_port_name is the name of the port for the PF in NIC+FCoE mode. You can identify the NIC port name from the NIC MAC address recorded in Step 1.

   # echo FCOE_ENABLE=\"yes\" > /etc/fcoe/cfg-enp133s0f0 
   # echo DCB_REQUIRED=\"no\" >> /etc/fcoe/cfg-enp133s0f0 
   # echo AUTO_VLAN=\"yes\" >> /etc/fcoe/cfg-enp133s0f0 
   # echo MODE=\"fabric\" >> /etc/fcoe/cfg-enp133s0f0

6. Enable the NIC port.

   # ifconfig enp133s0f0 up

7. Restart the lldpad and fcoe services.

   # service lldpad restart 
   # service fcoe restart

8. Run the fcoeadm -i command to query FCoE port information in the current system.
   Figure 4-280 Querying FCoE port information
   

   Before running the fcoeadm -i command, ensure that an FCoE connection has been established between the MZ522 and the switch module to which the MZ522 is connected.

9. Run the ifconfig command to query information of the NIC port corresponding to the FCoE port and obtain the FCoE VLAN ID (1002) allocated by the FCF.
