Using the Diagnostic-mode CLI
The Diagnostic-mode CLI includes a variety of tools for diagnosing MAX and network
problems. In most cases, use only the diagnostic commands that the procedures documented in
MAX manuals direct you to use unless instructed otherwise by Technical Support.
!
Caution:
Under most circumstances, diagnostic commands are not required for correct
operation of the MAX unit, and in some circumstances might produce undesirable results.
Contact Technical Support with any questions or concerns.
This section describes how to access and quit the Diagnostic-mode CLI, and introduces some
of the most commonly used diagnostic commands. For more information about using
diagnostic commands and for detailed information about interpreting command output, see the
Administration Guide.
Accessing and quitting the Diagnostic-mode CLI
Before you can access the Diagnostic-mode CLI, you must enable the Field Service and
Operations parameters in the active Security profile. (Set the values to Yes.) (For information
about Security profiles, see “Securing the MAX from unauthorized configuration changes” on
page 4-3.) The Field Service parameter enables or disables the ability to perform field service
operations, such as uploading new system software. The Operations parameter enables or
disables the ability to change parameter values. When Operations is set to No, most DO menu
commands, including those in the Diagnostic-mode CLI, are disabled.
To access diagnostic modes, use one of the following two methods:
•
At the MAX VT100 interface, display the DO menu by pressing Ctrl-D. Then press D or
select D=Diagnostics.
•
At the MAX VT100 interface, press the following key sequence in rapid succession:
Esc [ Esc =
(Escape key, Left Bracket key, Escape key, Equals key)
You must press all four keys within one second for the MAX to recognize the escape
sequence.
At any time, you can leave the Diagnostic-mode CLI by entering
quit
.
Using diagnostic commands
Enter diagnostic commands at the Diagnostic-mode CLI’s prompt (
>
), then press Return.
Use the commands only as directed in procedures described in MAX manuals or by Technical
Support.
