 Command Mode

 Canceling the Command

 Saving the Settings

1.1 Switch Port Number

which are listed in the following comparison table:

Interface type Name Simplified name

10M Ethernet Ethernet e

100M fast Ethernet FastEthernet f

1000M Ethernet GigaEthernet g

The expansion slot number in standard configuration is always 0. The others begin at 1
and continue from left to right.

Ports number in the same expansion slot is numbered from bottom to top and from left
to right, starting with 1. If only one port exits, it is numbered 1.

Note:

Ports in modules are numbered orderly from bottom to top and from left to right.

can be displayed if you enter the known characters and then a question mark
(without space).
Switch> s?

 The parameter list of a command will be obtained if you enter the command,
press "Space" and enter the question mark.
Switch# show ?

 The previously entered commands can be presented if you press the “up” arrow
key. If you continue press the “up” arrow key, more commands can be shown. If
you press the “up” arrow key and then the “down” arrow key, the next command
line following the current one can be presented.

1.4 Command Mode
The window for the switch’s command line can be in multiple modes: Each command
mode allows you to set a different suite on a switch, while the presently available
commands are up to your current command mode. Input a question mark to list all
commands available for current command mode The following table shows frequent
command modes:

Command Access mode Window prompt Logout mode

Configuration Preparation

Each command mode will certainly limit you to use a certain command subset. If you
have trouble in inputting a command, check the interface prompt and input the question
mark (?) for a list of available commands. You might be in the wrong command mode or
using incorrect syntax.

In the following example, please pay attention to the change of the window prompt and
its new command mode:
Switch> enter
Password: <enter password>
Switch# config
Switch_config# interface g0/1
Switch_config_g0/1# quit
Switch_config# quit
Switch#

1.5 Canceling the Command
If you want to cancel a command or resume the default attributes, usually add the “no”
keyword before most commands.

For example, no ip address.

1.6 Saving the Settings
You may need to save the configuration changes, so that you can recover the original
configuration in case of system restarted or power cuts. You can use write command to
save configuration in the Administration Mode or Global Configuration Mode.
