Is there a way to get the original MAC addresses for eth0 and eth1?
A large array of servers have bonding interfaces managing backup switch connections and one is misbehaving. With bond0 active both MAC addresses are replaced and reported identically by ifconfig.
I want to search the server array for a MAC address I found in a Cisco device.
I would use dmesg(1) or /var/log/messages, but they have been rolled over for hundreds of days for most of the array.
