DESCRIPTION
Select the check box to activate this policer.
Enter the descriptive name of this policer.
Select how the policer shapes the traffic of the member QoS classes.
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.
The Single Rate Three Color Marker (srTCM) is based on the token bucket filter
and identifies packets by comparing them to the Committed Information Rate
(CIR), the Committed Burst Size (CBS) and the Excess Burst Size (EBS).
The Two Rate Three Color Marker (trTCM) is based on the token bucket filter
and identifies packets by comparing them to the Committed Information Rate (CIR)
and the Peak Information Rate (PIR).
Specify the committed rate. When the incoming traffic rate of the member QoS
classes is less than the committed rate, the device applies the conforming action to
the traffic.
