Best way to manage Broadcast & multicast traffic

[ Edited ]

 

My vlans are in a large /18 network I would like to know the best way to manage bc/mc traffic? Right now we have broadcast-filter all on some VAPS not all. After I reviewed the user guide the options I have are below. Were not doing any video muliticasting or using airprint. 

-          Enabled bc-mc optimization on the SSIDs.

-          Enabled BC-MC optimization on the vlans.

-          Enabled DMO in the virtual ap profile.

-          broadcast-filter all on the virtual AP

 

Seems to me if use these 2 options should cover it the rest above are just redundant. 

-          broadcast-filter all on the virtual AP

-          Enabled BC-MC optimization on the vlans.

Re: Best way to manage Broadcast & multicast traffic

Turning on bcmc optimization on the vlan functions as broadcast filter all on the vap. Any VAP tied to that VLAN will have downstream broadcasts dropped.

Bcmc optimization​ on the SSID basically sends multicast traffic at higher rates (up to 24 meg). If you do not have true multicast in your environment, it will not make a difference to enable that.

Bcmc optimization at the vlan level is pretty much the one you need to accomplish your goals.

Re: Best way to manage Broadcast & multicast traffic

So I should remove broadcast-filter all from the VAPS and just      Enabled BC-MC optimization on the vlans should take care of it.
