Document URL:


Section Number and Name:

24.4. Configuring a Fibre Channel over Ethernet Interface

Describe the issue:

Step 1 gives as an example:

    # cp /etc/fcoe/cfg-eth0  /etc/fcoe/cfg-ethX

However, in a default install, there is no /etc/fcoe/cfg-eth0. Instead, there is a file named "cfg-ethx".

Suggestions for improvement:

Step 1 should give as an example:

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

Additional information:

While this is unfortunately confusing, it's correct. Just today I had a customer stumble on this, noting that there is no file "cfg-eth1".

Comment 3 Mason Loring Bliss 2017-05-19 19:19:33 UTC
Just noticed that the page seems to have been updated incorrectly.

We want:

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

Comment 5 Milan Navratil 2017-05-24 22:20:22 UTC
The fix is now available on the Red Hat Customer Portal:


 To configure a new VLAN, make a copy of an existing network script, for example /etc/fcoe/cfg-eth0, and change the name to the Ethernet device that supports FCoE. This provides you with a default file to configure. Given that the FCoE device is ethX, run:

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

Modify the contents of cfg-ethX as needed. Notably, set DCB_REQUIRED to no for networking interfaces that implement a hardware Data Center Bridging Exchange (DCBX) protocol client. 

Comment 7 Milan Navratil 2017-05-24 22:28:33 UTC
I shared an internal link in comment 5 by accident. This is the correct link to the updated version of the Storage Administration Guide on the Red Hat Customer Portal: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Storage_Administration_Guide/fcoe-config.html
