For example, when setting up a community string for SNMP to "public," do not use quotation marks around the string, or the string will include the quotation marks.

Command descriptions use the following conventions:

Vertical bars (|) separate alternative, mutually exclusive, elements.
Square brackets ([ ]) indicate optional elements.
Braces ({ }) indicate a required choice.
Braces within square brackets ([{ }]) indicate a required choice within an optional element.
Boldface indicates commands and keywords that are entered literally as shown.
Italics indicate arguments for which you supply values.

EXEC Mod e

To execute a command, type the command at the EXEC system prompt and press the Return key.

There are two EXEC prompt levels: privileged and user. The enable/disable command switches between the two EXEC levels. The user EXEC level prompt is available to users if they enter a password. This prompt is the server name followed by a pound sign (#), as in this example:

Console#

Use the Delete or Backspace key sequences to edit commands when you type commands at the EXEC prompt.

As a shortcut, you can abbreviate commands to the fewest letters that make them unique. For example, the letters sho can be entered for the show command.

Certain EXEC commands display multiple screens with the following prompt at the bottom of the screen:

--More--

Press the Spacebar to continue the output or press Return to display the next line. Press any other key to return to the prompt. Also, at the --More-- prompt, you can enter a ? to display the help message.

To leave EXEC mode, use the exit command at the system prompt:

Console# exit

Global Configuration Mode

To enter the global configuration mode, use the configure EXEC command. You must be in global configuration mode to enter global configuration commands.

Console# configure

Console(config)#

To exit global configuration mode, use the end global configuration command:

Console(config)# end

You can also exit global configuration mode by entering the exit command or pressing Ctrl-Z.

Interface Configuration Mode

To enter the interface configuration mode, from the global configuration mode prompt enter the interface you wish to configure:

Console(config)# interface ethernet 0

Console(config-if)#

The interface configuration commands are:

autosense

bandwidth

exit

fullduplex

halfduplex

These commands are described in the section following the global configuration commands.

To exit interface configuration mode, enter exit to return to global configuration mode:

cache4J(config-if)# exit

cache4J(config)#

Check Command Syntax

The user interface provides error isolation in the form of an error indicator, a caret symbol (^). The ^ symbol appears at the point in the command string where you have entered an incorrect command, keyword, or argument.

In the following example, suppose you want to set the clock. Use context-sensitive help to check the syntax for setting the clock.

An example of a mistake is:

Console# clock set 1222

                     ^
%Invalid input detected at `^' marker.
Console# clock ?

set      Set the time and date
Console# clock

The help output shows that the set keyword is required. Check the syntax for entering the time:

Console# clock set ?

hh:mm:ss Current time
Console# clock set

Enter the current time:

Console# clock set 13:32:00

% Incomplete command.

The system indicates that you need to provide additional arguments to complete the command. Press the Up Arrow to automatically repeat the previous command entry. Then add a space and question mark (?) to reveal the additional arguments:

Console# clock set 13:32:00 ?

<1-31> Day of the month
January Month of the year

Now you can complete the command entry:

Console# clock set 13:32:00 23 February 97

                                        ^
%Invalid input detected at '^' marker.

The caret symbol (^) and help response indicate an error at 97. To list the correct syntax, enter the command up to the point where the error occurred and then enter a question mark (?):

Console# clock set 13:32:00 23 February ?

<1993-2035> Year
Console# clock set 13:32:00 23 February

Enter the year using the correct syntax and press Return to execute the command:

Console# clock set 13:32:00 23 February 1997

System Help

You can obtain help when you enter commands by using the following methods:

For a brief description of the context-sensitive help system, type help.
To list all commands for a command mode, enter a question mark (?) at the system prompt.
To obtain a list of commands that start with a particular character set, enter an abbreviated command immediately followed by a question mark (?).

Console# cl?

clear  clock

To list a command's keywords or arguments, enter a question mark (?) in place of a keyword or argument on the command line:

Console# clock ?

  clear  Clear the current time from the battery-backed clock
  save   Save the current time into the battery-backed clock
  set    Set the local time and date

Save Configur ation Changes

To avoid losing new configurations, save them to NVRAM:

Console# copy running-config startup-config

Console# Ctrl-Z

Console# write

See the command description for the copy running-config startup-config command for more information on the running versus saved configuration modes.

Ctrl-Z does not save the configuration; it only exits from the global
configuration mode.
