NIC Naming Conventions And Vmware

I have a couple of CentOS 7 machines running in a vmware environment. On all the older ones I’ve deployed, the NIC is named ens160, but on all of the new ones, it is named ens192. I can’t find any difference in the hardware that would account for this.

Any suggestions on what I can do to figure out why some are named ens160
and some ens192?

Thanks.

  • Hi John,

    This may not be helpful but I can confirm that you should be getting consistent naming. Normally I actually get something like eno16777984 But I have a couple systems that get named in the way that you mention. When this happens I
    normally see ens160 as the first nic and 192 if a second is defined. I haven’t dug too deeply into this but I would suggest that you look at the udev rules that are defined in /etc/udev/rules.d/ and see if this explains what is happening. You may also want to check that the VMware Hardware version is what you expect.
