I see large amounts of ARP traffic from the network with a single client on a test SSID bridged on a production vlan.
I have proxy-arp enabled by default, or at least I think so (see https://docs.aerohive.com/330000/docs/help/english/ng/Content/gui/configuration/configuring-manageme...). I have also enabled filtering unwanted broadcast traffic at the SSID, but I can see tons of broarcast ARP coming in on the client (wireshark capture on the wifi interface).
The same vlan is used by production networks for XIQ-Controller. Clients associated to SSIDs there do not see broadcast storms or other unwanted broadcast traffic coming in.
So it is technically possible to block unwanted broadcasts and ARP, and I have to find out which knob to use.
Is this old proxy-arp bug and the workaround still a thing? https://extremeportal.force.com/ExtrArticleDetail?an=000099277 Customer is experiencing Broadcast storms which seems to come from Access Points
How do you preserve airtime from unwanted ARPs?
