I can give you the current arp table, but we do not log ARP so there’s no way to tell you what the table looked like at that particular time.
Or we need to wait for the next time if someone in Engineering is available to get an ARP (I am not maning routers unfortunately)
Do you want me to send you the current ARP?

It seems to be a network problem. What is the arp cache on the router
when this happens?
