This is by far my biggest drawback with Meraki, otherwise I use these where I can. I've learned to utilize the syslog functions (we use Rapid7.) It would do so much for Meraki to be able to show a live monitor (like Palo, Fireppower and others...)...

On ISE, have you need to enable weak ciphers option in allowed protocols? Otherwise a test from Meraki dashboard will not hit your ISE rules.
