    No idea.  I have the same question.  I did this because of that 20 packet and max burst to 7.5 Mbps comment.  I'm not sure if this will even work:

     

    access-list 174 permit ip 129.1.46.128 0.0.0.127 any
    !
    class-map match-all XYZ321
     match access-group 174
    !
    policy-map XYZ321
     class XYZ321
      police cir 2500000 pir 7500000
        conform-action transmit
        exceed-action transmit
        violate-action drop
      bandwidth 2500
      queue-limit 20
    !
    map-class frame-relay FRTS
     service-policy output XYZ321

    Isn't this policy applied to the interface which was configured with FRTS in previous task? If yes, limit 20 packets and burst up to 7.5M are controlled by map-class/FRTS.

    So remaining part would be only about guarantee 2.5M in case of congestion.

    This is my understanding of the task/solution.

    Cheers,

    Seba

    Seba,

    That is how I see it.  The lesson of this task is...   Beware of the wording of each task and factor in previous task objectives if necessary.
