What is snArpStatsInvalidSource?
This read-only Counter32 tallies the total number of ARP packets received with an invalid sender protocol address. It flags malformed or suspicious ARP traffic to an admin, which can indicate a misconfigured host or, in some cases, an ARP spoofing attempt using an invalid source address. A steady stream of snArpStatsInvalidSource increments from one segment would prompt an admin to investigate which device on that LAN is sending malformed ARP packets.
