Configuring Shadow Nodes

Before you configure shadow nodes:

• Configure the traffic classes.

  See Configuring Traffic Classes That Define Service Levels.

• Configure the queuing hierarchy.

  See Configuring Queue Profiles to Manage Buffers and Thresholds.

• Configure the scheduler hierarchy and shaping with scheduler profiles.

  See Configuring a Scheduler Hierarchy.

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.
