ISE 2.4 Android 8 BYOD

dsserubi

Am attempting to perform Android BYOD in a lab using the BYOD portal and also tried within the Guest Flow. The strange thing is that after getting redirected and getting to the 3rd step where I need to download the NSA from play store (Already installed on the device), as soon as I launch the app and accept the certificates as per the prompts, ISE sends a COA terminate and the reason is because "posture status changed".

This causes the BYOD flow to fail because the original session was terminated and get an error message "Unable to download profile. (Have you logged into the guest portal?)". Am using NSP 2.2.0.54

Checked some bugs that state updating the posture DB which I've done.

Any Ideas?

I tried my Nexus 5X running Android 8.1 yesterday at our alpha deployment and it worked fine. Thus, it seems something wrong with your portals. I would suggest to try new portals.

Please have a look at some of the BYOD design guides so you can cross reference your setup.
