I have a case of clients on my LAN losing its MAC address. This seems to happen randomly to clients even though they had both an IP address and MAC addresses (when "arp") during the initial boot up.
After the MAC address is lost (incomplete), I am unable to ping or ssh to that client; nor does a reboot work.
Anyone have ideas?
Description of LAN (closed system, not connected to the internet). - ~100 clients all set to static IP address through /etc/network/interfaces - ~1 core switch - ~16 access switches (daisy chained) - Linksys router
