You can add a banner to give users helpful information before or after logging
            in.
    
    - 
        To add a banner to your switch, use the
          following command:
        
configure banner {after-login | { before-login } { acknowledge } | before-login {acknowledge} save-to-configuration} 
        When using before-login, you have to select the
            save-to-configuration option so that the change is saved to the
          configuration file to have it show up in output of the show configuration {module-name} {detail}
 command.
        When you use the acknowledge option, users
          must press a key to get the login prompt.
        
          When no options are specified, the command configures a banner for a CLI session that
            appears before login. A CLI banner can have a maximum size of 24 rows with 79 columns of
            text. 
         
       - 
        To clear a configured banner, use the
          following command:
        
unconfigure banner { after-login |
            before-login } command.
       - 
        To disable the acknowledgment feature
          (which forces the user to press a key before the login screen appears), use the following
          command omitting the acknowledge option:
        
configure banner {after-login | { before-login } { acknowledge } | before-login {acknowledge} save-to-configuration} 
        
       - 
        To display the banners that are
          configured on the switch, use the following command:
        
show banner { after-login | before-login
            }
