Missing broadcast-filter arp checkbox, is it already enabled?

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.

It is on by default, so it would not show up in the configuration.

 

Try this:

 

show wlan virtual-ap <name of virtual ap>

Hey Colin,
