Yes, OnGuard can check in with ClearPass without actually using the posture
data in a NAD enforcement.
The way the licensing works is the same as base CPPM. ClearPass counts each
unique device authenticated using posture data over a 7 day window on a
rolling basis. The information is then averaged at the end of the month into
a 7 day rolling average. And just like CPPM, authentication will continue if
you exceed your license for more than 4 months but you will warning messages
in the UI. Please reach out to your Aruba SE if you need more clarity on
this.
