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.
