    How do you configure a basic QoS map to match Voice Traffic?

      How do I actually verify that it's working properly?

          @travisrigby - The links below go over how to configure a basic QoS map over the web interface and CLI:

          There are some statistics you can look at to verify whether packets are matching the QoS map and, in some cases, whether prioritized traffic is being dropped due to insufficient priority bandwidth being available.


          In the web interface, you can navigate to the "QoS Maps" page and look under the 'Map Conversation Statistics' to see the matched packets and dropped packets for interfaces that have been assigned QoS policies using class-based bandwidth queuing or priority rate limiters.


          In the CLI, you can use the command, "show qos map interface <interface>". Below is an example of this output:


          router#show qos map interface eth 0/1


          eth 0/1

            qos-policy out: Voice


            map entry 5

               match IP packets with a DSCP value of 46

               priority bandwidth: unlimited

                 note: since unlimited, other qos bandwidths cannot be assured

               packets matched: 11108252, bytes matched: 2803803116


            map entry default

               packets matched: 37485213, bytes matched: 4794475242

               5 minute offered rate 17168 bits/sec, drop rate 0 bits/sec
