My ISP has said they will set up their side to give 50% policed real time traffic and 30% for our application traffic burstable then 5% anything else burstable. The QOS below is my attempt to do this but I was advised that to apply it to the Dialer 1 interface I hade to create a second policy-map (ADSLOut) which had the class-default and the child policy (QOSADSL) within that.
When I did this I can't apply it to the Dialer 1 interface but if I use the child policy then it will allow me to apply that, will this work the same way.
class-map match-all RealTime match ip dscp ef class-map match-all General match any class-map match-any Application match ip dscp cs3 match ip dscp af41 ! policy-map QOSADSL class RealTime bandwidth percent 50 class Application priority percent 30 class General priority percent 5 class class-default shape peak percent 85 policy-map ADSLOut class class-default service-policy QOSADSL
bandwidth 1240 ip nbar protocol-discovery ip flow ingress ip flow egress load-interval 30 tx-ring-limit 3 tx-queue-limit 3 service-policy output QOSADSL
My first opinion is a recomendation: in the policy-map, when you're configuring LLQ use the priority command for delay-sensitive traffic (Voice) and the bandwidth command for the rest. This is because the priority command is used to indentify a class as a "strict priority class" which in my opinion should be the voice traffic and the bandwidth command is used to allocate bandwidth to nonpriority classes.
The interface is not letting you apply the service-policy because you have to configure shaping inside the class-default of the parent policy-map. This shape is going to be the value in bps that you want to assing to the traffic classes that you've configured. For example, let's say that you want to allocate 1Mbps for all the classes.
policy-map QOSADSL class RealTime priority percent 50
class Application bandwidth percent 30
class General bandwidth percent 5
class class-default shape peak percent 85
policy-map ADSLOut class class-default shape average 1000000 service-policy QOSADSL
