Parameter
Incoming: Sets the login banner for users that log in through modems. If you specify
to authenticate login users, the banner appears after a user passes the authentication.
(The session does not appear in this case.)
login: Sets the login banner. The banner set by this keyword is valid only when users
are authenticated before they log into the switch and appears while the switch
prompts for user name and password.
shell: Sets the session banner, which appears after a session is established. If you
specify to authenticate login users, the banner appears after a user passes the
authentication.
text: Banner to be displayed. If no keyword is specified, this argument is the login
banner. You can provide this argument in two ways. One is to enter the banner in the
same line as the command (A command line can accept up to 255 characters.) The
other is to enter the banner in multiple lines (you can start a new line by pressing
<Enter>,) where you can enter a banner that can contain up to 2000 characters
(including the invisible characters). Note that the first character is the beginning
character and the end character of the banner. After entering the end character, you
can press <Enter> to exit the interaction.
Description
Use the header command to set the banners that are displayed when a user logs into
a switch. The login banner is displayed on the terminal when the connection is
established. And the session banner is displayed on the terminal if a user successfully
logs in.
Use the undo header command to disable displaying a specific banner or all
banners.
Note that if you specify any one of the three keywords without providing the text
argument, the specified keyword will be regarded as the login information.
