Cisco IOS IP Configuration Guide
Example: How to Find Command Options
This section provides an example of how to display syntax for a command. The syntax can consist of
optional or required keywords and arguments. To display keywords and arguments for a command, enter
a question mark (?) at the configuration prompt or after entering part of a command followed by a space.
The Cisco IOS software displays a list and brief description of available keywords and arguments. For
example, if you were in global configuration mode and wanted to see all the keywords or arguments for
the arap command, you would type arap ?.
The <cr> symbol in command help output stands for “carriage return.” On older keyboards, the carriage
return key is the Return key. On most modern keyboards, the carriage return key is the Enter key. The
<cr> symbol at the end of command help output indicates that you have the option to press Enter to
complete the command and that the arguments and keywords in the list preceding the <cr> symbol are
optional. The <cr> symbol by itself indicates that no more arguments or keywords are available and that
you must press Enter to complete the command.
Table 2 shows examples of how you can use the question mark (?) to assist you in entering commands.
The table steps you through configuring an IP address on a serial interface on a Cisco 7206 router that
is running Cisco IOS Release 12.0(3).
