    Configuring a QoS Profile

    Before you configure a QoS profile:

    To configure a QoS profile:

    1. Create a QoS profile and enter QoS Profile Configuration mode.
      host1(config)#qos-profile qosp-vc-queuing host1(config-qos-profile)#
    2. (Optional) Configure a group node for each interface.
      host1(config-qos-profile)#atm group groupA scheduler-profile scheduler1 statistics-profile statpro-1

      When you configure a group node, you can also reference a default or named traffic-class group, a scheduler profile, or a statistics profile.

      If you do not specify a traffic-class group, the group node defaults to the default group. Each traffic class can belong to only one traffic-class group (either the default group or a named group).

      The router supports up to four traffic-class groups above a given port.

    3. (Optional) Configure a scheduler node for interfaces.
      host1(config-qos-profile)#atm node scheduler-profile scheduler1 group strict-priority

      When you configure a scheduler node, you can also reference a default or named traffic-class group and a scheduler profile.

      The scheduler profile supplies a relative weight and potentially a shaping rate to be applied at the scheduler node.

      Note: You cannot associate a scheduler profile with a port-type interface unless you also specify the strict-priority group.

    4. (Optional) Configure a queue for interfaces in the specified traffic class.
      host1(config-qos-profile)#atm queue traffic-class strict-priority scheduler-profile scheduler1 queue-profile queue1 drop-profile drop1

      When you configure a queue, you can include any of the following profiles:

      • The scheduler profile supplies a relative weight and potentially a shaping rate to be applied at the queue.
      • The queue profile supplies threshold information for the queue if the router defaults are not appropriate.
      • The drop profile supplies dropping behavior of a set of egress queues.

        Each queue traffic class can appear in only one traffic-class group.
