assigned to it. During congestion, the packets of each priority class exceeding the assigned
bandwidth are discarded.
•
Bandwidth queuing (BQ)—An AF queue. The BQ provides guaranteed bandwidth for AF
traffic, and schedules the AF classes proportionally. The system supports up to 64 AF queues.
•
Default queue—A WFQ queue. The default queue transmits the BE traffic by using the
remaining interface bandwidth.
The system matches packets with classification rules in the following order:
•
Match packets with priority classes and then the other classes.
•
Match packets with priority classes in the configuration order.
•
Match packets with other classes in the configuration order.
•
Match packets with classification rules in a class in the configuration order.

RTPQ

RTP queuing (RTPQ) is designed for delay-sensitive, real-time traffic (such as voice and video). You
can assign voice or video packets to a high-priority queue by specifying a UDP port range as the
match criterion. These packets are given strict priority service and are sent before packets in other
queues are sent.
RTPQ can be used with FIFO, PQ, CQ, or WFQ, but not CBQ. CBQ can use LLQ to provide priority
service for real-time traffic.
