Cisco IOS Command Modes

Cisco IOS Command Modes

The Cisco IOS user interface is divided into many different modes. The commands available to you
depend on which mode you are currently in. Enter a question mark (?) at the system prompt to obtain a
list of commands available for each command mode.
When you start a session on the access point, you begin in user mode, often called user EXEC mode.
Only a limited subset of the commands are available in user EXEC mode. For example, most of the user
EXEC commands are one-time commands, such as show commands, which show the current
configuration status, and clear commands, which clear counters or interfaces. The user EXEC
commands are not saved when the access point reboots.
To have access to all commands, you must enter privileged EXEC mode. Normally, you must enter a
password to enter privileged EXEC mode. From this mode, you must enter privileged EXEC mode
before you can enter the global configuration mode.
Using the configuration modes (global, interface, and line), you can make changes to the running
configuration. If you save the configuration, these commands are stored and used when the access point
reboots. To access the various configuration modes, you must start at global configuration mode. From
global configuration mode, you can enter interface configuration mode and line configuration mode.
