Ingress policing provides the ability to monitor the data rates for a particular class of traffic and perform action when traffic exceeds user-configured values. This allows users to control ingress bandwidth based on packet classification. Ingress policing is done by a policing meter which marks incoming traffic and performs actions based on the results of policing meters.

By default, the DSCP and ECN bits of VXLAN bridged packets are not rewritten. Currently, for bridged packets undergoing VXLAN encapsulation, the DSCP in the outer IP header is derived from TC and the ECN bits are set to zero. The desired behavior is that the outer IP header should be remarked with ingress packet DSCP and ingress packet ECN. Also, local congestion should be handled correctly.
