Symbols You may see a variety of symbols shown as part of the command syntax.
These symbols explain how to enter the command, and you do not type
them as part of the command itself.
Table 7 summarizes command syntax
symbols.

and an address for
<ip_address>
when entering the command. Do not type the angle
brackets.

arguments can be specified. For example, in the syntax

you must specify either the primary or secondary image when entering the
command. Do not type the square brackets.
