I have atrunked link between a Cisco 3550 and a Cisco 3750. This trunk carries a number of VLANs as well as being used as a Layer 3 OSPF link for lots of other VLANs. One of the VLANs that is trunked is the Voice VLAN.
One end of the trunk is set to "mls QOS trust dscp" and the other is set to "mls QOS Trust Cos"
All of the interfaces that connect the phone are set to "mls qos trust dscp"
Is there any reason why these are different? Should they both be using the same value or is it only locally significant? I am guessing that as long as the correct Cos-Dscp maps are in place then in doesn't matter if you use dscp or cos?
