Verification Examples for DSCP-Based WRED
Example 11-7 shows sample output for the show policy-map interface command. In this example,
DSCP-based weighted random early detection is configured on the nyusers class queue. The output
shows the exponential weight of 9 used to calculate the average queue size. In this case, WRED has not
dropped any packets based on DSCP 8 and DSCP 0 (default).
