----
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:
\\ 
    cceda895-dd2b-4096-9d9c-5985dd0872d7
\\ 
You can now add this line to your interface config file (/etc/sysconfig/network-scripts/ifcfg-eth0 in this example)
