QOS, priority between "Switchport priority..." and auto qos.

Hello,

What would happen if you have an interface with both Switchport priority extend cos "value", and then an AUTO QOS VOIP TRUST. Since they are conflicting, I assume the manual extend cos "value" would be used? (For a PC attached to the phone)

AUTO QOS VOIP TRUST is used for IP Phones only it doesnot trust the PC COS. You have to manually configure the "Switchport priority extend cos "value" command to override the COS vlaue sent by the PC. It is recommended to have that command, auto QoS doesn't enable that. So if you normally do use that command, it is recommended to have it with auto QoS also.
