There are five types of banner messages:
Message-of-the-day banner (MOTD): A message-of-the-day (MOTD) banner is displayed when a user connects to the
router on all connected terminals. This banner is displayed at login and is useful for sending messages that affect all
network users. The banner motd command in global configuration mode can be used to configure a MOTD banner
message.
Login banner: A login banner is configured to be displayed on all connected terminals. This banner is displayed after MOTD banner appears and before the login prompt. The banner login command in global configuration mode can be to configure a login banner message.
EXEC banner: Depending on the type of the connection, an EXEC banner is displayed after the user successfully logs the router. An EXEC banner is configured to be displayed whenever an EXEC process is initiated. For example, this banner
is displayed to users telneting to the system after entering their usernames and passwords, but before the user EXEC prompt is displayed. The banner exec command in global configuration mode can be used to configure an EXEC banner
message.
Incoming banner: An incoming banner is displayed on terminals connected to reverse Telnet lines, usually initiated from
the network side of the router.
