Task Display configuration information about a WRED table or all WRED tables. Command display qos wred table [ name table-name ] [ slot slot-number ] WRED configuration example Network requirements Apply a WRED table to interface Ten-GigabitEthernet 1/1/6, so that the packets are dropped as follows when congestion occurs: • To use better effort to forward higher-priority traffic, configure a lower drop probability for a queue with a greater queue number. Set different drop parameters for queue 0, queue 3, and queue 7. • Drop packets according to their colors. In queue 0, set the drop probability to 25%, 50%, and 75% for green, yellow, and red packets, respectively. In queue 3, set the drop probability to 5%, 10%, and 25% for green, yellow, and red packets, respectively. In queue 7, set the drop probability to 1%, 5%, and 10% for green, yellow, and red packets, respectively. • Enable ECN for queue 7.
