    Configuring Shadow Nodes

    Before you configure shadow nodes:

    To add a shadow node to a QoS profile:

    1. Create a QoS profile and enter QoS Profile Configuration mode.
      host1(config)#qos-profile shadowNode host1(config-qos-profile)#
    2. Configure a scheduler node for each interface of the specified type.
      host1(config-qos-profile)#atm node scheduler-profile default
    3. Configure a shadow node for each interface of the specified type.
      host1(config-qos-profile)#atm shadow-node scheduler-profile default
    4. Configure a queue for interfaces in the specified traffic class.
      host1(config-qos-profile)#atm queue traffic-class strict-priority scheduler-profile scheduler1
    5. (Optional) Configure a traffic-class group and reference a scheduler profile in the QoS profile.
      host1(config-qos-profile)#atm group default scheduler-profile default

    The router creates the shadow node when the following conditions are met:

    • After all the nodes and group nodes are created.
    • If the queues are not at the required scheduler level.
    • When a node of the same interface type has existed in the same group of the scheduler hierarchy.
