802.11ac only

[Mark]

How do I make the Access Point only support 802.11ac or 802.11n. Is there a way to only support certain protocols without allowing things like 802.11a and 802.11b?

The only thing I see if what I provide. I don't see an "n-only" or an "n and ac" selection.

Hello Mark,

Data rates can be configured on the radio or wlan. As Andrew mentioned, you can select custom data rates and allow certain data rates only, if you so choose.

Using the chart that Andrew provided you can select the specific n or ac rates. Custom data rates can be configured on both the WLAN itself or on the radio interface. It is suggested to configure data rates on the WLAN.

802.11n and 802.11ac are actually collections of various different mcs rates.
If you select custom, you can then specify which MCS rates exactly you want to support.
If you type ? at the end of the data-rates CLI you'll see a list of what's supported.

This chart explains the different MCS rates in general.
