Maybe I'm overlooking something obvious, but so far I haven't been able to see in CPPM how to create a rule that applies only during a specified time period. Our goal is to prevent students from accessing the wifi network during school hours using their personal devices, while allowing access for their district-issued laptop; at the same time, we don't want to restrict staff from any wifi access. So it's really a two-fold issue - keeping students off during class hours, and specifying that this apply only to non-district devices. I'm sure the second part is addressed by machine authentication, but the time-based rule escapes me.
