Traffic Policing and Traffic Shaping Features Supported by the Device
To make full use of limited network resources, you can police and shape specific service flows to adapt to the allocated network resources.
Traffic Policing
The device supports the following traffic policing features:
Interface-based traffic policing
Controls all incoming traffic on an interface regardless of packet types. Interface-based traffic policing discards excess traffic to limit the incoming traffic within a proper range and to protect network resources.
Management interface-based traffic policing
Limits traffic on the management interface. This is because CPU usage becomes high and services are interrupted if there is heavy traffic on the management interface due to malicious attacks or network exceptions.
Flow-based traffic policing
Limits the rate of traffic matching traffic classification rules. The device monitors the rate of traffic of a specified type and discards excess packets to limit traffic of this type within a proper range and protect network resources. Flow-based traffic policing uses dual token buckets.
The S2700SI does not support traffic policing based on a traffic classifier.
Traffic Shaping
Interface-based traffic shaping
Shapes all the packets that pass through an interface.
Queue-based traffic shaping
Shape packets in different queues on an interface. Therefore, the device can shape traffic based on service types, such as audio, data, and video services.
