  • 1.  CoS BA-Classifier sequence

    Posted 08-27-2012 07:08

    Hello,

     

    i have a question to the sequence of the BA-Classifier.

     

    In a BA-Classifier i can use DSCP or 802.1p to match a packet, but what happens when a Paket has both (DSCP and 802.1p) marker set and the marker match to different queue´s.

     

    Which marker DSCP or 802.1p is the primary and will be use?

     

    Thanks for help

     

    Andre S.

    I’ve mostly worked on QFX3500 series and DSCP supersedes CoS in that case.

    My guess is that it should be same for all products, but then it could be platform specific as well.  Which platform are you planning to deploy this on?

     

    Thanks,

    Hello ankit,

     

    thanks for your answer.

     

    I will deploy it on ex-3200, ex-8200 and ex -4200 with Junos 12.1R1.9.

    np, Andre!

    I remember reading something like this during the JNCIP studies.. DSCP will be prioritized over .1p.

     

    Cheers,

    #Priority
    #DSCP
    #.1ip
    #BA
    #.1p
    #COS

    Hi,

     

    it sounds very logical with, primary DSCP und sec. 802.1p.

     

    Thank

    Hi Guys,

     

    I am thinking about the same question right now. It would be nice to have a precise answer from Juniper on that topic.
