Primary Modes
The two primary modes of operation are user EXEC mode and privileged EXEC mode. Tthe privileged EXEC mode has a higher level of authority in what it allows the user to do with the device.
User EXEC Mode
The user EXEC mode has limited capabilities but is useful for some basic operations. This mode is the first mode encountered upon entrance into the CLI of an IOS device.
This is often referred to as view-only mode. The user EXEC level does not allow the execution of any commands that might change the configuration of the device.
By default, there is no authentication required to access the user EXEC mode from the console. However, it is a good practice to ensure that authentication is configured during the initial configuration.
The user EXEC mode is identified by the CLI prompt that ends with the > symbol. This is an example that shows the > symbol in the prompt: Switch>
Privileged EXEC Mode
The execution of configuration and management commands requires that the network administrator use the privileged EXEC mode, or a more specific mode in the hierarchy.
The privileged EXEC mode can be identified by the prompt ending with the #symbol. Switch#
By default, privileged EXEC mode does not require authentication.
Global configuration mode and all other more specific configuration modes can only be reached from the privileged EXEC mode.
Global Configuration Mode and Submodes
Global configuration mode and interface configuration modes can only be reached from the privileged EXEC mode.
From global config, CLI configuration changes are made that affect the operation of the device as a whole.
Switch# configure terminal
Switch(config)#
From the global config mode, the user can enter different subconfiguration modes. Each of these modes allows the configuration of a particular part or function of the IOS device.
Interface mode - to configure one of the network interfaces (Fa0/0, S0/0/0)
Line mode - to configure one of the physical or virtual lines (console, AUX, VTY)
To exit a specific configuration mode and return to global configuration mode, enter exit at a prompt. To leave configuration mode completely and return to privileged EXEC mode, enter end or use the key sequence Ctrl-Z.
As commands are used and modes are changed, the prompt changes to reflect the current context.

Banner Configuration
- 1. Cisco Networking: Banner Configuration YASER RAHMATI www.yaser-rahmati.ir Switch(config)#banner motd # Enter TEXT message. End with the character '#'. This device is for authorized personnel only. If you have not been provided with permission to access this device - disconnect at once. # Message of the Day (MOTD): This type of logon message has been around for a long time on Unix and mainframe systems. The idea of the message is to display a temporary notice to users, such as issues with system availability. However, because the message displays when a user connects to the device prior to login, most network administrators are now using it to display legal notices regarding access to the switch, such as unauthorized access to this device is prohibited and violators will be prosecuted to the full extent of the law and other such cheery endearments. Switch(config)#banner login # Enter TEXT message. End with the character '#'. *** Login Required. Unauthorized use is prohibited *** # Switch(config)#banner exec # Enter TEXT message. End with the character '#'. *** Ensure that you update the system configuration *** *** documentation after making system changes. *** # Login : This banner is displayed before login to the system, but after the MOTD banner is displayed. Typically, this banner is used to display a permanent message to the users. Exec: This banner displays after the login is complete when the connecting user enters User EXEC mode. Whereas all users who attempt to connect to the switch see the other banners, only users who successfully log on to the switch see this banner, which can be used to post reminders to your network administrators.
