I have a pair of Netgear GS752TP switches running firmware 6.0.0.64, and they appear to be incorrectly logging. Both switches regularly log an "ARP-E-ARPTBL: ARP Table Overflow" error. Each time I see these logs, though, I look at the table on the switch, and it shows 110-120 entries. That's correct for the environment they're in, and well under the 4K MAC address table limit on this model of switch.
From the packet sniffing that I've done, I do not believe that there's a problem in the network with a malicious attempt to overflow the table or a device malfunctioning and spamming ARP advertisements. That leads me to believe that the switch is probably incorrectly logging this error, but has anyone else seen this with their Netgear switches and have a solution?
