3430 and 10.8 code QOS

Jump to solution

I have a lot of 3430 routers on metro-e type scenarios and QOS is not working correctly.  Has anybody had problems with the 10.8 code and QOS.

I have done some extensive testing and it appears that QOS is working as it is hitting the qos maps but I can completey kill a VOIP DSCP 46 call across the WAN.

I have tested this on 10mb metro-e and on a single T1 with the same results.  I currently have a strict policy to limit the normal data traffic so that it cannot overwhelm the links.

This is happening on several of my customers networks.

qos map SHAPE10mb

  map entry 10

    match any

    class shape rate: 10000 (kilobits/sec), average

    qos submap VOICE10mb

        submap entry 10

          match dscp 46

          match precedence 5

          priority bandwidth: 1000 (kilobits/sec)  burst: default

        submap entry 11

          match dscp 38

          class bandwidth:  1800 (kilobits/sec)

        submap entry 12

          match dscp 34

          class bandwidth:  50 (kilobits/sec)

        submap entry 13

          match ip list IVIEW

          class bandwidth:  2000 (kilobits/sec)

        submap entry 20

          match any

          priority bandwidth: 5100 (kilobits/sec)  burst: default  strict-rate-limiting

Thank you for asking this question in the support community.  Is it possible you can reply with the current configuration (please, remember to remove any information that might be sensitive to the organization)?  I will be happy to review the configuration and application and hopefully provide some recommendations.  Also, do not hesitate to reply with any additional questions or information.  I will be happy to help in any way I can.

I have tried with the traffic shape command on the interface and without and of course it has made no difference.  Currently the traffic shape command is on the WAN (metro-e) interface.  It is a 10mb pipe and we limited to 9.5mb as they are giving us no headroom.

It appears you have opened a ticket with ADTRAN Technical Support about this.  When you come to a resolution, will you please post the outcome here to benefit other community members with similar questions?
