We have recently switch MPLS providers and they are requiring that we use CoS tagging on our router interfaces. All of our sites use 1800 or 2800 series routers. When I create all of the maps and attempt to apply the CoS to the interface, ny routers inform me that you cannot apply CoS to a layer 3 interface? I cnnot seem to find any CoS examples on a layer 3 interface. Zny help would be greatly appreciated.
I have this problem too.
