  • Hi Experts,

The below config is applied on an uplink toward a distribution switch cisco 6800.

I couldn't find the class map configuration, can any one write the class map config for the below policy-map(1P7Q3T). Also what is the policy map config that i should apply on the user facing interface for classification and marking??

C3850(config-pmap-c)# policy-map 1P7Q3T
C3850(config-pmap)# class VOICE
