Applying a WRED Profile to Traffic

After you create a WRED profile, you must specify on which traffic the system applies the profile.
The system assigns a color-coded drop precedence — red, yellow, or green — to each packet based on the
fourth bit of the 6-bit DSCP field in the packet header before queuing it.
• If the fourth DSCP bit is 0, packet is marked as green.
• If the fourth DSCP bit is 1, the packet is marked as yellow (except for DSCP 63, which is marked as red).
• If you do not configure honor DSCP values on ingress packets (trust diffservcommand), all traffic
defaults to green drop precedence. See
information.
• Assign a WRED profile to either yellow or green traffic.
