Managing System Resources for Shadow Nodes
Each ASIC hardware type provides different node and queue resources.
Level 1 queues stack directly above the port; level 2 queues stack above a node and the port. The router implicitly creates the level 1 and level 2 queues.
Shadow node queues stack above a port node, a level 1 node, and a shadow node. Therefore, the shadow node queue is at level 3. The router does not implicitly create any nodes for the queues.
You can configure 64,000 level 1 queues using shadow nodes by specifying the group and shadow node rules in the QoS profile. Each level 1 queue is stacked above the port, the group node, and the shadow node; therefore, it requires 64,002 descriptors.
Table 1 lists the number of nodes required to create a queue.

| Level 1 Queues | Level 2 Queues | Shadow Node Queue |
|---|---|---|---|
| Required Nodes | 3 | 2 | 1 |
