I'm getting ready to enable the "Drop Broadcast and Unknown Multicast" knob on a single VAP profile for testing purposes. After reading about this, it sounds like ARP broadcasts could be dropped, but only if the "Broadcast-filter ARP" knob is disabled. Unfortunately, it appears that there isn't even a checkbox for this knob!
Some other posts indicate that this knob is actually under the VAP profile in the guise of "Convert Broadcast ARP requests to unicast", which I already have enabled. My concern is that the web UI seems to indicate in two places what may be the same thing.
So, what is the correct way to enable Broadcast-filter ARP? I have also logged on to the CLI and issued
show run | inc broadcast show run | inc filter show run | inc arp show configuration | inc broadcast show configuration | inc filter show configuration | inc arp
But none of those returns any results pertaining to Broadcast-filter ARP.
Solved! Go to Solution.

It is on by default, so it would not show up in the configuration.
show wlan virtual-ap <name of virtual ap>
