Example: Defining Different Drop Behavior for Each Traffic Class for WRED

32
The thresholds specify a linear relationship between average queue length and drop
probability.
You can express thresholds as either percentages of maximum queue size by including
the keyword percent, or as absolute byte values by omitting the keyword.

Figure 5 on page 32 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

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 33 shows an example
