Create an input policy-map containing all three class-maps, and assign each class-map a different service queue. ip access-list class-map match-any policy-map-input service-queue Create two input QoS policies, one each for PC data and voice signaling. Assign a different bandwidth weight to each policy. qos-policy-out bandwidth-weight Create an output policy map containing both QoS policies, and assign them to different service queues. policy-map-out service-queue Assign a strict priority to unicast traffic in queue 3. strict-priority Apply the input policy map you created in Step 2 to the interface connected to the phone, and apply the output policy map you created in Step 4 to the interface connected your desired next-hop router. service-policy Command Mode CONFIGURATION CLASS-MAP CONFIGURATION POLICY-MAP-IN CONFIGURATION QOS-POLICY-IN CONFIGURATION POLICY-MAP-OUT CONFIGURATION INTERFACE The following example is a screenshot showing some of the steps above, and the resulting running-config.
