# Example: Shadow Nodes on Different Traffic-Class Groups

This example shows how to configure shadow nodes on different traffic-class groups. After adding the voice queue in the auto-strict priority group named strict, the system stacks the IP voice queue above the Ethernet port, the voice group, and the phantom node.
