Configure Banner in Cisco devices

A banner is a message presented to a user who is using the Cisco switch. Based on the type of banner you configured for use, the message will be shown to users of Cisco switch. Cisco IOS routers support a number of banners, such as:

• MOTD banner: When users connect to the router, the "Message Of The Day (MOTD)" banner is presented.
• Login banner: The login banner is displayed right before the authentication prompt.
• Exec banner: The Exec banner appears before the user sees the exec prompt.
• Incoming banner: These banners are displayed for users who connect through reverse telnet.
