Creating a new Banner

Three steps are required to change the login banner. They are listed here.

• Create a text file containing the new banner in the switch’s flash directory.

• Add the

UI_add_do_alert()

command syntax to the switch’s mpx.cmd file.

• Enable the feature by executing the

alert

{console | telnet | ftp}

command.

To create the text file containing your banner you may use the

create file

command in the UI’s

edit buffer sub-menu. This method allows you to create the file in the flash directory without
leaving the

console session. You can also create the text file in an external editor (such as

MS Wordpad) and ftp the file to the switch’s flash directory. In either case, be sure to remem-
ber the name of your file.

To add the

ui_add_do_alert()

command syntax to the switch’s

mpx.cmd

file, use the edit

command of the

’s

file

sub-menu. (For information on using the file sub-menu, refer to

Chapter 7, “Managing Files”).

To enable the new login banner, add the

alert {console |telnet | ftp}

syntax to the

mpx.cmd

file,

using the

edit

command of the

’s

file

sub-menu. This command will cause the banner

message to display at each login until the switch is rebooted. After a reboot, the switch will
not display the banner unless the

alert

command is executed again.

Permanent Banner

If you want the banner message to display after the system has been rebooted, you must add
additional lines to the

mpx.cmd

file. The following example lists the commands you must add

to the

mpx.cmd

file. This example uses a banner text file with the name

“banner.txt”

cmDoDump=1
cmInit
ui_add_do_alert()
change_prompt_file(“console”, “banner.txt”)
change_prompt_file(“telnet”, “banner.txt”)

♦ Note ♦

Any commands added to the

mpx.cmd

file must be

added after the lines

cmDoDump=1

and

cmInit

. If the

commands in the

mpx.cmd

file are not in the proper

order the switch may not boot properly.

Banners for Different Access Methods

You may use different banners for sessions accessed by console, Telnet or ftp methods. To do
this, create different text files for each banner with unique filenames. When you add the
commands to the

mpx.cmd file

, use the filenames to associate the banner with the session

access methods. Here is an example:

cmDoDump=1
cmInit
ui_add_do_alert()
change_prompt_file(“console”, “console_banner.txt”)
change_prompt_file(“telnet”, “telnet_banner.txt”)
change_prompt_file(“ftp”, “telnet_banner.txt”)
