Using the Cisco IOS CLI

Catalyst 4224 Access Gateway Switch Software Configuration Guide
OL-2031-02
In the following example, which uses the default prompt (router>), notice how the
prompt changes after each command to indicate a new command mode:
router> enable
Password: <enable password>
router# configure terminal
router(config-if)# line 0
router(config-line)# controller t1 1/0
router(config-controller)# exit
router(config)# exit
router#
%SYS-5-CONFIG_I: Configured from console by console
The last message is normal and does not indicate an error. Press Return to return
to the prompt.
Note You can press Ctrl-Z in any mode to return immediately to privileged EXEC
mode (router#), instead of entering exit, which returns you to the previous mode.
Disabling a Command or Feature
If you want to undo a command you entered or disable a feature, enter the
keyword no before most commands; for example, no mgcp.
Saving Configuration Changes
You need to enter the copy running-config startup-config command to save
your configuration changes to nonvolatile random-access memory (NVRAM), so
the changes are not lost if there is a system reload or power outage; for example:
router# copy running-config startup-config
Building configuration...
Note It might take a minute or two to save the configuration to NVRAM. After the
configuration has been saved, the privileged EXEC mode prompt (
router#)
reappears.
