I'm looking for some help supplying end-to-end QoS for our ISP customers. Currently, I have a scenario setup where i have a Cisco 1841 CPE. It connects to our 7206VXR via PPPoA. The 1841 classifies traffic and marks the DSCP bit appropriately. On our 7206, I want to apply the DSCP marking to the MPLS EXP bit for transport across our backbone. I have this scenario working on 802.1q subinterfaces, but am having trouble with ATM subinterfaces.
I have been working from http://www.cisco.com/warp/public/121/where_policy.html#input_policies . The CPE does seem to be lablelling the DSCP bit (as you can see from the "show policy-map" output) , and the traffic is routing normally, but the 7206 appears to be not seeing the DSCP lables. Will the "show policy-map interface input" on the 7206 only show results when congestion is taking place? Any suggestions would be MOST welcome. See the attachment for show runn, show policy-map interface, etc.
