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

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

Configuring QoS in AOS in the GUI (video) - https://supportforums.adtran.com/videos/1046

Configuring QoS for Voice over PPP WAN Interface (CLI) - https://supportforums.adtran.com/docs/DOC-2654

Configuring QoS for Voice over Ethernet WAN Interface (CLI) - https://supportforums.adtran.com/docs/DOC-3406

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

Let us know if you have any further questions.

Thanks,

Noor
