Parameters
Parameters are often required elements of a command; however, for some
commands, parameters are not required. A parameter is most often a value that you
specify after the keyword. There are different types of parameters, such as strings,
integers, or IP addresses.
The CLI indicates the type of parameter that you must enter. When you see a range
of numbers or uppercase letters, it indicates that you must specify a value. For
example:
Keywords and Parameters Together
By combining keywords and parameters in the correct sequence, you can begin
using the CLI to configure and monitor your router. For example, you could specify
the command hostname to change the name of your router by entering a keyword
and a parameter. You need to type only the portion of the keyword that makes it
unambiguous, such as hostn. Here, the value of the parameter, which is the name
you assign to the host, is a string of up to 64 characters.
When you enter this command, the new hostname appears in the prompt.
Another example is a command that requires you to enter a number from within a
given range. The command ip http port requires that a value be entered for the
portNumber parameter. The value of this parameter is a number in the range of
0–65535. For example, you could enter:
32
