Re: QOS Q.

First you will need to trust the switchport the device is connected to, by either issueing trust cos, or if you have IP phones trust ipphone, then on the uplink port to the router you need to trust the dscp by issuing "mls qos trust dscp", you will also require dscp-cos and mapping. On the router itself you dont need to do any mapping nor trust, simply create your LLQ configuration to match for dscp values.

HTH,

Chris
