Multi-Level Priority Queues
First Published: November, 2006
The Multi-Level Priority Queues (MPQ) feature allows you to configure multiple priority queues for
multiple traffic classes by specifying a different priority level for each of the traffic classes in a single
service policy map. You can configure multiple service policy maps per router. Having multiple priority
queues enables the router to place delay-sensitive traffic (for example, voice) on the outbound link before
delay-insensitive traffic. As a result, high priority traffic receives the lowest latency possible on the
router.
