If the end device triggered some sort of log event, for instance a DHCP reject, it will be identifiable by looking the log data since the output will display interface, MAC address, and IP address on the same output line. Which will output the contents of the log buffer before the buffer was flashed. Each time a computers TCP/IP stack uses ARP to determine the Media Access Control (MAC). Though this is not exactly a solution, you can try An ARP cache is a simple mapping of IP addresses to MAC addresses.
