Generate UUID for Network Interface

Jun 2017

If you do not have the UUID (Universal Unique Identifier) identifiers in your ifcfg-xxx files, you can generate these IDs from the command line. Bear in mind each time you run this command for an interface, a new UUID is generated, and presumably the old one becomes invalid.

To generate a UUID:

  uuidgen <interface>
  uuidgen eth0

This will return a value that looks similar to the one below:


You can now add this line to your interface config file (/etc/sysconfig/network-scripts/ifcfg-eth0 in this example)
