    qos traffic marked?

    nativepdx New Member

      Adtran document states "By default, AOS voice products will tag generated RTP with DSCP 46" .

       

      Does that infer that any RTP traffic that is handled by the router gets marked? OR only RTP traffic that originated on another Adtran device?

       

      AND on Map Conversion Statistics - Dropped Packets   does this report matched packets dropped or ANY packets dropped to accomodate qos map prioritized traffic?

          Thank you for asking this question in the support community.

           

          The statement you are referring to is related to AOS voice products that generate their own RTP.  This does not include RTP packets that are simply passing through an AOS unit.

           

          Can you provide additional information about which QoS statistic you are referencing?  Are you asking about the "packets dropped" output from the show qos map interface <slot/port> command?  I will be happy to explain the statistics as best I can.

           

          Please, do not hesitate to reply to this post with any additional questions or information.

              Levi,

               

              I was actually referring to Map Conversation Statistics dropped packets(bytes) .  the QOS map I built has unlimited priority bandwidth so I wondered if I saw dropped packets would they be a match to the map or would they be other lower priority packets. 

               

               

              thanks

                  The output I was referring to with the show qos map interface <slot/port> CLI command is displayed in the web interface under "Map Conversation Statistics."  The "Dropped Packets" indicate there was congestion on the interface where the QoS map is applied, which forced packets matching that QoS sequence queue to be dropped.

                   

                  Furthermore, please, use the priority unlimited command with extreme caution as it could prevent vital Layer 2 traffic from being processed. A network outage could occur when excessive priority traffic is present and consumes all of the available bandwidth on the interface.

                   

                  I hope that makes sense, but please let me know what questions you have.
