Hi @GinaR ,
The WIDS/WIPS solution for Meraki access points is Air Marshal. It works by containing rogue access points that are not recognised on your dashboard network. 6 GHz containment will not work because 6 GHz uses protected management frame and it would not be possible to contain the clients over the air. This will be true for any Meraki access point.
I would recommend going through the entire article to get a broader understanding of the options Air Marshal provides. If you have any questions about the content, let us know here and we can help to address them.
