WPA-Enterprise encryption with 802.1X authentication is the method of choice for providing secure access in an Enterprise WLAN environment. Unfortunately it’s also notoriously tricky to configure, with a range of possible configuration issues involving the three key players in the system (client devices, access points, and the RADIUS authentication server itself).
We’re pleased to announce a handy diagnostic tool in our Enterprise Cloud Controller which helps identify many problems with a custom 802.1X setup.
After configuring your RADIUS server for 802.1X, you now have the option of testing your setup directly from Meraki Dashboard:
If all goes well, you’ll see results like this:
If there are test failures, however, you’ll see results like these:
In this example there was a timeout while attempting to reach the server from one out of five APs tested. This error often results from forgetting to add an AP’s IP address to the whitelist on your RADIUS server, and it’s usually a very difficult error to discover and debug.
We think this is a useful tool that makes it super easy to troubleshoot the security of your WLAN. In addition, this tool provides peace of mind that each AP can authenticate users correctly. Automated testing is especially valuable in large, 100+ AP environments, where testing each AP manually could literally take days.
We look forward to hearing your feedback about it!
