Example: Shadow Nodes over VLAN and IP Queues

This example illustrates how and when the system creates shadow node after you
configure it.
In the first part, you specify an Ethernet node, an Ethernet group node, a VLAN node,
a VLAN shadow node, and an IP queue. Because the IP queue is at a proper scheduler
level without the shadow node, the system does not create a shadow node.
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
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.
