Both Cisco Swich and Router can be configured to display messages with command "banner" under global configuration mode.
Use the banner command to set the banner text. Separate the text with a delimiting character.
Router (config) #banner motd #This is the banner.#
There are four banner types:
- MOTD (Message of the day) -- Displayed first
- Login -- Displayed before the login promp
- EXEC--Displayed after login, before the router prompt
- Incoming--Displayed for incoming lines(reverse Telnet)
The MOTD banner is displayed to all terminals connected and is useful for sending messages that affect all users (such as impending system shutdowns). Use the no exec-banner or no motd-banner command to disable the MOTD banner on a line. The no exec-banner command also disables the EXEC banner on the line. When a user connects to the router, the MOTD banner appears before the login prompt. After the user logs in to the router, the EXEC banner or incoming banner will be displayed, depending on the type of connection. For a reverse Telnet login, the incoming banner will be displayed. For all other connections, the router will display the EXEC banner.
