## 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)#ethernet node
host1(config-qos-profile)#ethernet group default scheduler-profile default
host1(config-qos-profile)#vlan node
host1(config-qos-profile)#vlan shadow-node
host1(config-qos-profile)#ip queue traffic-class best-effort scheduler-profile default

`

In the second part, you specify an Ethernet node, a VLAN node, a shadow node, and a VLAN queue. The system creates the shadow node so that the VLAN queue is at the proper scheduler level.

`

host1(config-qos-profile)#ethernet node
host1(config-qos-profile)#vlan node
host1(config-qos-profile)#vlan shadow-node
host1(config-qos-profile)#vlan queue traffic-class best-effort scheduler-profile default
