My question is kind of silly but I feel lost. I am reading the BCMSN self-study book and right now I am at the special-case 802.1Q trunk used between Cisco IP phones and catalysts. There's a statement "if you use the command switchport voice vlan untagged, you can still carry CoS information over the trunk". Well, I don't see how this would work since all data and voice traffic is carried over the native VLAN and is untagged. 802.1p is located in the different trunk encapsulation methods and if data and voice are sent over the native vlan, how is this going to work? Am I missing something?
