Verification Example for Discard-Class-Based WRED
Example 11-11
shows sample output for the
show policy-map interface
command when
discard-class-based WRED is configured on the vlan1 class queue. For each discard-class level, the
output indicates the minimum and maximum thresholds, the mark probability value, the number of
packets dropped using RED, and the number of packets dropped using tail drop.
Example 11-11 Displaying Discard-Class-Based WRED Statistics
Router#

Service-policy output: bronze
Class-map: vlan1 (match-all)
