Hi,
Before updating the ISE posture data base, Android 4.0 Is working but neither 5.0 nor 6.0 versions. However once the the posture update is done, Both Android 5.0 and 6.0 are started working. (Downloading the certificates and profile as expected).
Need 8443 port open from ISE IP to internet to get posture database updated.
ISE version 1.3 patch 5.
Current license Base and advanced.
