  1. Hi Rene,

    Why only switches and wireless devices are used to configure for re-marking traffic?
    We do it for qos traffic confidentiality ?
    The PHB logic is setting QoS marking for every devices right ? According to that do we need to re- match the traffics along the way , I am not clear about that…

    Thnx , Thnx & Thnx again

  2. Hi, Rene.

    Reading this tutorial I had a doubt: what is the difference of I configure the command set precedence and set ip precedence or even if it was set dscp or set ip dscp into the policy-map? What changes in time of the router should mark the packet?

    Thank you in advance

  3. Hello Stafanio

    According to Cisco, the set ip dscp command was replaced with the set dscp command:

    set dscp - 12.2(13)T - This command was introduced. It replaced the set ip dscp command.

    Similarly, the set ip precedence command was replaced with the set precedence command:

    set precedence - 12.2(13)T This command was introduced. This command replaces the set ip precedence command.

    More information about these commands from Cisco can be found here.

    I hope this has been helpful!


  4. Would it be possible for you to provide marking examples using ECN and CoS?

  5. Is it possible for you to cover Layer 2 QoS in more detail?

    Just going off the blueprint you are expected to know queueing, scheduling, classifcation and marking techniques
