Appendix D: Serial Port and Telnet Commands
Superuser Commands
122 | SmartBits 600x/6000x Installation Guide
ECHO ON – Allows text entries through the serial port to be echoed while entered.
ECHO ON allows the user to see their keystrokes as they occur. It is the default echo
setting.
ECHO OFF – Does not allow text entries through the serial port to be displayed while
being entered. The ECHO state is temporarily forced to ECHO OFF during all password
entry sessions.
CARDS SHOW – Displays the use and status of all cards being used.
ETH SHOW – Displays the current operational configuration of the chassis controller’s
(host) Ethernet port. This information includes the current speed and duplex settings.
SU – Enter super-user mode, enables the super-user command set. This command
provides entry into the super-user mode, where the current logged-on Ethernet
connections on the unit can be examined, and if desired, closed. The super-user mode is
password protected and prompts you for an 8-character password. The factory default
password is SMB-6000.
Superuser Commands
These commands are available under the superuser mode of the SmartBits 6000x
controller chassis using either the serial port or Telnet interface.
USERS – Sets the way log-in and card reservation permissions are handled. These
command parameters can be combined into groups to better understand their functionality.
USERS SHOW|STATUS – (A command for information purposes only.) Lists those
users currently logged in to the chassis, and which cards those users have reserved. A
single character will designate if the user has (S) super-user or (A) administrative
privileges, or if the user is on a (T) Telnet connection. The status command is used only
for displaying user information regarding cards reserved with the USER RESERVE
command. If no users have cards reserved for them in this manner, an empty table will be
displayed.
USERS RESERVE/RELEASE [ipaddress][cardlist] – Reserves the cardlist for
exclusive access by the host at ipaddress. Card reservation is terminated with the release
command.
USERS ALLOW|DISALLOW [ipaddress] – Removes the ability of any host matching
ipaddress to log in to the chassis. The allow switch removes this limitation, but does not
grant any special privileges.
USERS MAXIMUM [1...15] – Displays the current setting for the maximum number of
users allowed to concurrently log in to the chassis (when entered without a number). The
maximum number of users must be a number between 1 and 15.
USERS CLOSE [1...15/ALL] – Closes the connection(s) for either the indicated usernum
or for ALL users. A console (serial port) connection does not have a user number and
cannot be closed.
