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). Committed Rate 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.

Policer Setup: Add/Edit
The following table describes the labels in this screen.
Table 53
Policer Setup: Add/Edit
LABEL
DESCRIPTION
Active
Click this switch to enable or disable the policer. When the switch turns blue
, the function is
enabled. Otherwise, it is not.
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.
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).
Committed
Rate
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.
