When operating in hybrid mode all qos is configured in catos. We are using an ethernet WAN service and need to pass voice over the WAN, however the catos desn't support traffic shaping on ethernet ports, only policing. I should be able to use an aggregate policer to ensure the link bandwidth is not completely consumed by non voice traffic, this is how I'm thinking of reserving bandidth on the ethernet link for voice traffic. If you have any thoughts about this I would appreciate your feedback.
