How to explicitly name network interface in enps0fX convention for the overcloud nodes ?

Solution Verified - Updated -

Issue

  • When I just use the 4 onboard 1Gbps interfaces I can use the NIC aliases, but I also have additional 2 dual port 10G network cards within my server. When I want to use them the system boots at all, regarding wrong pointing of interfaces. So can you please explain where I can find the overcloud interface mapping, meaning is my enoX is mapped to nic1 or is ens1fX linked to nic1?
  • Currently, for Red Hat Enterprise Linux Openstack 7 - the names are similar with ethx, but by default, for RHEL-7, I think it should enps0fX.
  • How about the benefit and disadvantage for both cases?
  • Where I can find the interface mapping, meaning is my eno1 is mapped to nic1 or is ens1f0 linked to nic1?

Environment

  • Red Hat OpenStack 7.0
