Cisco CSR 1000v Series User Manual

Finding 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
XE 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.
The following examples show how you can use the question mark (?) to assist you in entering commands.
