Example-1: The example below demonstrates how to configure an application priority QoS policy with target interfaces and multiple QoS schedulers. The policy includes a voice scheduler with 30% bandwidth allocation and tail-drop behavior, and a video scheduler with 20% bandwidth allocation and RED drop behavior for queue management.
