VX1410A & VX1420A IntelliFrame Mainframe Instruction Manual
The command header has a hierarchical structure that may be represented by a
command tree (see Figure 3–3). An easy-to-remember word called a mnemonic
designates each level of the hierarchy. A colon separates the levels.
The top level of the tree is the root level. A root node is a mnemonic 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 header path and leaf node together form the command header. Figure 3–4
shows the command header for the leaf node indicated in Figure 3–3.

You must include values for commands that have parameters. In this manual, the
< > symbols enclose the parameter type when stating the syntax of the com-
mand. For example, the syntax of the command in Figure 3–5 includes the
<NRf> parameter type.
