Example: Configuring Different Treatment of Colored Packets for WRED
Figure 5 on page 33 shows a WRED drop profile that yields progressively more
aggressive drop treatment for each color. Exceeded traffic is dropped over a wider
range and with greater maximum drop probability than conformed or committed
traffic. Conformed traffic is dropped over a wider range and with greater maximum
drop probability than committed traffic.
The commands to configure this example are:
host1(config)# drop-profile wredColored
host1(config-drop-profile)# committed-threshold percent 30 90 3
host1(config-drop-profile)# conformed-threshold percent 25 90 5
host1(config-drop-profile)# exceeded-threshold percent 20 90 10

Example: Defining Different Drop Behavior for Each Traffic Class for WRED
You can define different dropping behaviors for each traffic class in the router. By
doing so, you can assign less aggressive drop profiles to higher-priority queues and
more aggressive drop profiles to lower-priority queues. Figure 6 on page 34 shows
an example that classifies packets into one of four traffic classes. Each traffic class
has a different queueing behavior, drop treatment, and scheduler treatment.
