MR18 - Single Device Packet Flood

I see repeatedly a "Single Device Packet Flood" event coming out of one Access Point. Could this event lead to a packet flood and disrupt uplink traffic to internet.

It seems like a device on the wifi is flooding the AP with broadcast traffic.

More info can be seen in the air marshal docs

Typically flooding will cause problems when buffers are overloaded or specific devices (DHCP servers, gateways etc) are overwhelmed by requests.

It's difficult to say exactly whether this would cause a major impact in your environment but I would think most enterprise equipment should be able to deal with 1000 packets in a 10 second interval.
