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,
The older running Centos 7?
All machines are in the same vmware host?
It is not your case, but are interesting: https://access.redhat.com/solutions/2592561

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.
Thanks. _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

The difference comes from the virtual machine host operating system definition and the virtual network adapter type selected where the first choice constrains the available options for the second.
