Configuring RED Drop Profiles on ACX Series Routers
You enable RED by applying a drop profile to a scheduler. When RED is operational on an interface, the queue no longer drops packets from the tail of the queue. Rather, packets are dropped after they reach the head of the queue.
To configure a drop profile, include the drop-profiles statement at the [edit class-of-service] hierarchy level:
[edit class-of-service] drop-profiles { profile-name { fill-level percentage drop-probability percentage; } }
After you configure a drop profile, you must assign the drop profile to a drop-profile map, and assign the drop-profile map to a scheduler, as discussed in Determining Packet Drop Behavior by Configuring Drop Profile Maps for Schedulers.
