I recently had to determine the mac addresses for all 4 interfaces on a production server which I could not touch (it’s in production…duh). Only three of the 4 interfaces were plumbed so ifconfig -a would not help getting the mac-address of the 4th interface. I searched the internet and found someone else who had the problem and saw a suggestion that I tried in my situation. A note made by the person suggesting the command left me skeptical but I tried it anyway. Turns out it was exactly what I needed. Here is the command and the output.
bash-2.05$ /usr/sbin/prtconf -pv |grep local-mac-address
