Color conforming classes must be one of the following types:
•
Primary COS
•
Secondary COS
•
DSCP
•
IP Precedence
This includes both the input and color aware classes. The conform color class
may not be the same as the input class, nor may the match criteria be of the
same type. The input class map may have a match type of "any."
The exceed color class may only be specified for the two-rate police
algorithm.
Example
The following example uses a simple policer to color TCP packets that exceed
an average rate of 1000 Kbps or a burst size of 16 Kbytes as red. Conforming
packets (those in CoS queue 1) are pre-colored green prior to metering. After
metering, non-conforming packets are colored red. Both green and red
packets are transmitted, but may be subject to further color-based action on
egress. The example configuration below also shows the configuration of
WRED drop thresholds and probabilities for colored traffic.
