2-19.2 Port Policing
This page lets you configure Policer settings for all switch ports. A policer can limit the bandwidth of
received frames. It is located in front of the ingress queue.
Port Policing is useful in constraining traffic flows and marking frames above specific rates. Policing is
primarily used for data flows and voice or video flows because voice and video usually maintain a steady
rate of traffic.
To set QoS Port Schedulers in the web UI:
1. Click Configuration, QoS, Port Policing.
2. Select which ports to enable the QoS Ingress Port Policers and type the Rate limit condition.
3. Scroll to select the Rate limit Unit (kbps, Mbps, fps or kfps).
4. Click Apply to save the configuration.
