Figure 3-2: Tree hierarchy
The top level of the tree is the root level. A root node is located at the root level. A
root node and one or more lower-level nodes form a header path to the last node
called the leaf node.
The command header is configured by header path and leaf node. Figure 3-3
shows the command header for the leaf node.
