question for DoS function on the 6900 switch

Does the OS600switch support function like the CoPP(Control Plane Policing) of Cisco? If some traffic overflows on the switch from any DDoS attack that time switch need to reduce the bandwidth on the interface.

How do I modify my question what I asked?? Anyway, I want to know whether OS6900 supports COPP or not. And, If that feature support, could you let me know how to configure that function?
