DESCRIPTION
Policer Setting
Enable
Select the check box to activate this policer.
Name
Enter the descriptive name of this policer. You can use up to 31 alphanumeric characters, it must
begin with a letter. The valid characters are [0-9][a-z] [A-Z][_-].
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).
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.
Committed
Burst Size
Specify the committed burst size for packet bursts. This must be equal to or less than the peak
burst size (two rate three color) or excess burst size (single rate three color) if it is also configured.
This is the maximum size of the (first) token bucket in a traffic metering algorithm.
Excess Burst Size
Specify the burst size of packet bursts above which the SBG will perform the non-conforming
action.
