Thanks Gianluca, I can't access https://access.redhat.com/solutions/2435891 unfortunately, but https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/consistent-network-interface-device-naming_configuring-and-managing-networking looks like it might help me.

See here if you have access: https://access.redhat.com/solutions/2435891 Anyway perhaps you could manage order of names customizing /usr/lib/systemd/network/99-default.link At least as described here: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/consistent-network-interface-device-naming_configuring-and-managing-networking but I never tried it HIH, Gianluca _______________________________________________ CentOS mailing list CentOS at centos.org https://lists.centos.org/mailman/listinfo/centos
