Hello.
This was my input from a previous post with same requirements...
You can 2 sets of the same policies. The 1st set will have both traffic shaping and scheduler configured. Depending on the scheduler configuration, this set of policies will be enabled/disabled -- and along with it, the traffic shaping configuration
If the first set is disabled(due to schedule), then the 2nd set of policies will take effect.
Just need to make sure both sets of policies are the same (service, address objects, etc.). Not the cleanest way, but I can't think of another way.
Regards,
Sam
