l
For queues with the priority value 0, the lowest discard threshold is 30 kb, the highest
discard threshold is 100 kb, the discard probability is 90%, and the average queue
length indicator is 8.

For queues with the priority value 1, the lowest discard threshold is 120 kb, the highest
discard threshold is 200 kb, the discard probability is 80%, and the average queue
length indicator is 8.

For queues with the priority value 2, the lowest discard threshold is 220 kb, the highest
discard threshold is 300 kb, the discard probability is 70%, and the average queue
length indicator is 8.
Configuration Flow
1.
Create a class-map and match it with precedence 0-2.
2.
Create a policy-map, add the new class matching precedence 0-2 to the policy, and
add the queues of different priorities in the class to WRED.
3.
Select a PQ from the policy classes.
4.
Bind the policy-map to the egress direction of the interface.
Configuration Commands
1.
Configure the class.
ZXR10(config)#class-map pre0-2 match-all ipv6
ZXR10(config-cmap)#match precedence 0-2
ZXR10(config-cmap)#exit
2.
Configure the policy.
ZXR10(config)#policy-map wred
ZXR10(config-pmap)#class pre0-2
ZXR10(config-pmap-c)#random-detect enable
ZXR10(config-pmap-c)#random-detect weight 8
ZXR10(config-pmap-c)#random-detect precedence 0 30 100 90
ZXR10(config-pmap-c)#random-detect precedence 1 120 200 80
ZXR10(config-pmap-c)#random-detect precedence 2 220 300 70
ZXR10(config-pmap-c)#priority-level 1
ZXR10(config-pmap-c)#exit
ZXR10(config-pmap)#exit
3.
Bind the policy to the interface.
ZXR10(config)#service-policy gei-1/7 output wred
Configuration Verification
Check policy configuration.
ZXR10(config)#show policy-map
