WRED profile to a policy-map so that specified traffic can be prevented from consuming too much of the

BTM resources.

WRED uses a profile to specify minimum and maximum threshold values. The minimum threshold is the

allotted buffer space for specified traffic, for example, 1000KB on egress. If the 1000KB is consumed,

packets are dropped randomly at an exponential rate until the maximum threshold is reached (as shown

in the following illustration); this procedure is the “early detection” part of WRED. If the maximum

threshold, for example, 2000KB, is reached, all incoming packets are dropped until the buffer space

consumes less than 2000KB of the specified traffic.

You can create a custom WRED profile or use one of the five pre-defined profiles.

Creating WRED Profiles

To create WRED profiles, use the following commands.

1. Create a WRED profile.

CONFIGURATION mode

wred-profile

2. Specify the minimum and maximum threshold values.
