Usage Guidelines

Use the aaa authentication banner command to create a personalized message that appears when a user logs in to the system. This message or banner will replace the default message for user login.

To create a login banner, you need to configure a delimiting character, which notifies the system that the following text string is to 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 character in the extended ASCII character set, but once defined as the delimiter, that character cannot be used in the text string making up the banner.

Examples

The following example shows the default login message if aaa authentication banner is not configured. (RADIUS is specified as the default login authentication method.)

aaa new-model
aaa authentication login default radius

This configuration produces the following standard output:

User Verification Access
Username:
Password:

The following example configures a login banner (in this case, the phrase "Unauthorized use is prohibited.") that will be displayed when a user logs in to the system. In this case, the asterisk (*) symbol is used as the delimiter. (RADIUS is specified as the default login authentication method.)

aaa new-model
aaa authentication banner *Unauthorized use is prohibited.*
aaa authentication login default radius

This configuration produces the following login banner:

Unauthorized use is prohibited.
Username:
