Many servers have PCI cards for NICs in addition to those on the motherboard (if any). For example, most of my file servers have eight ethernet interfaces (six 1GBE, two 10GbE). On my Dell servers, the built-in interfaces are labeled on the back panel. However, at least in CentOS 6, you can call the interfaces anything you want by suitably changing /etc/udev/rules.d/70-persistent-net.rules. The names used have to be consistent with /etc/sysconfig/network-scripts/ifcfg-* of course. BTW, I have some workstations that have only a single interface, and that comes up as p2p1. I actually like the new scheme better, but don't get me started on the use of UUID in /etc/fstab... Steve
