What do you mean, "slot"? All of my servers, and our systems at home, the NIC's on the m/b. What "slot" is that? Is it labeled *anywhere*?
No, of
course not.
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.
I can think of one server we've got, a Dell PER815, that's got a NIC (that we don't use, dunno why it was in there), and four onboard.
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...
I disliked it when the first time I started doing sysadmin, on a Sparcserver 20, back in the mid-nineties, and I don't like it any better now. Among other things, too easy to mistype one of the letters or numbers.
About UUIDs, though, I think we can start on that in harmony. UUID is *so* much easier to remember, and shorter than, say, the serial number on the disk label... oh, right, it's twice as long....
