I am not sure if we can direct Meraki MX to look at ISE, and ISE to look at some database (users, auths, etc...? Access points currently installed are Cisco Aironet. I am trying to see what can/cannot ISE do with Mereki MX firewalls?
You can use ISE as a RADIUS server for 802.1x/EAP-on-LAN on the small branch MXs that support 802.1x on their LAN ports. The RADIUS for splash page, the splash pages are actually served from the dashboard shard infrastructure. Hence the RADIUS request actually comes from the dashboard, not the MX.
I haven't been great about keeping up with all what models are available. I saw a couple other posts that talked about certain MXs not be able to do 802.1x and wasn't sure. Thanks for helping make it clearer for me.
