For example, the input to my script/program is the network interface name, like bge0/ix0, and the output is the physical port which maps to this interface, like, LOM1/LOM2 or NIC1 port 1 (in case a NIC card is attached via the PCI bus). This program/script will run on a Dell PowerEdge server. > > LOM stands for LAN On Motherboard. It sounds like you're looking for something like Dell's biosdevname for Linux. I don't think such a thing exists on FreeBSD, but if you can figure out how to get it the same data should be available from the BIOS. I would start by scrutinizing the output of "dmidecode"; if it's in there then you can just parse it out for your script. If not, you can always dive through the source of biosdevname: http://linux.dell.com/git/biosdevname.git/
