[CentOS] NIC config documentation?

Does anyone have a favorite howto or other succinct document that that 
describes how to set up networking on a multi-nic host when you don't 
know ahead of time which nic is which?   I usually muddle through it by 
plugging in one wire at a time, using mii-tool to see which link is up, 
then ifconfig on that interface to get the HWaddr to put in the 
corresponding /etc/sysconfig/network-scipts/ifcfg-eth? file.  But now I 
need to train some other people how to do it and it seems like there 
should be a better way.
