Connecting Ingress and Egress Traffic

All incoming traffic is sorted into five queues or forwarding paths that can be
controlled separately. Each queue allows for a different qualities of service
and provides a specific type of treatment to traffic. All traffic on a single queue
is treated the same.
These five queues or levels are:
■

You can customize any of these queues, although EF is the most restrictive.
You can also configure the drop packet probabilities (1, 2, or 3) for the AF
queues.
