Active

Select the check box to activate this policer.

Name

Enter the descriptive name of this policer.

Meter Type

This shows the traffic metering algorithm used in this policer.

The Simple Token Bucket algorithm uses tokens in a bucket to control 
when traffic can be transmitted. Each token represents one byte. The 
algorithm allows bursts of up to b bytes which is also the bucket size.

Maximum 
Rate

Specify the guaranteed rate at which packets are admitted to the network. 

This is to specify how many bytes of tokens are added to a bucket every 
second.

Burst Size

Specify the guaranteed amount of bytes that are admitted at the 
committed rate. 

This is the maximum size of the (first) token bucket in a traffic metering 
algorithm.

Available 
Class

Selected 
Class 

Select a QoS classifier to apply this QoS policer to traffic that matches the 
QoS classifier.

Highlight a QoS classifier in the Available Class box and use the > button 
to move it to the Selected Class box.

To remove a QoS classifier from the Selected Class box, select it and use
