Egress traffic-policing can be applied on L3 Ethernet subinterfaces for outbound traffic.

The document describes the support for dedicated and group ingress policing on interfaces without using QoS policy-maps to match on the traffic and apply policing.

This document describes the support for interface policing counters on interfaces where interface policing feature is configured. Counters for this feature provide information on how many packets are being allowed or dropped on a given interface via the policers configured. The counters are only supported on interfaces where dedicated policers are configured.

If two or more streams of packets are subjected to the same policer, the policing may not be fair, that is, the policer might exhibit bias towards one of the streams. Fair policing across all the streams is not guaranteed. Policer fairness provides a way to reduce this bias and maintain fair distribution of policer bandwidth among the input streams proportional to the ingress rate.

Storm control enables traffic policing on floods of packets on L2 switching networks. Support was enabled for Front panel ports and Lag in eos-4-25-2f with storm-control-speed-rate-support. Now, storm control will be supported per subinterfaces( both ethernet and port-channel). Scale of subinterfaces is 4095. 

The document describes the support for policing on one or more VNIs configured on a Vxlan interface. This feature allows dedicated policing of flows on a VNI in both directions which corresponds to incoming traffic from a remote VTEP and outgoing traffic towards a remote VTEP. Policers in the hardware are created with policer profiles attached to VNIs. Policer profiles can be shared across multiple VNIs but policers are dedicated.
