Login Banner

Information About Login Banner

Login banner is used to display a warning or message when you try to login to the controller.

To create a login banner, you must configure a delimiting character that notifies the system that the following text string must be displayed as the banner, and then the text string itself. The delimiting character is repeated at the end of the text string to signify the end of the banner. The delimiting character can be any single character in the extended ASCII character set, but once defined as the delimiter, that character cannot be used in the text string for the banner.


Note

When HTTP authentication is configured using TACACS+/RADIUS, the banner message does not display on the Web UI.
