Configuring Shadow Nodes
Before you configure shadow nodes:
- Configure the traffic classes.
- Configure the queuing hierarchy.
See Configuring Queue Profiles to Manage Buffers and Thresholds.
- Configure the scheduler hierarchy and shaping with scheduler profiles.
To add a shadow node to a QoS profile:
- Create a QoS profile and enter QoS Profile Configuration
mode.host1(config)#qos-profile shadowNode host1(config-qos-profile)#
- Configure a scheduler node for each interface of the specified
type. host1(config-qos-profile)#atm node scheduler-profile default
- Configure a shadow node for each interface of the specified
type.host1(config-qos-profile)#atm shadow-node scheduler-profile default
- Configure a queue for interfaces in the specified traffic
class.host1(config-qos-profile)#atm queue traffic-class strict-priority scheduler-profile scheduler1
- (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.
