Configuring Quality of Service Parameters

This section discusses quality of service (QoS) parameters that can be configured for the 1700 series
platforms when using the ADSL WIC. The following features are included:

Low Latency Queuing (Priority Queuing with Class-Based Weighted Fair
Queuing)
Low latency queuing (LLQ) allows strict priority queuing (PQ) to class-based weighted fair queuing
(CBWFQ). This priority queuing allows delay-sensitive data such as voice packets to be de-queued and
sent before other packet traffic, reducing jitter in voice conversations. To configure LLQ, enter the
priority command under the CBWFQ configuration.
Configuration Example
The following example shows a Cisco 1751 router configured with LLQ.
