Command Line Interface - Microsemi SyncServer S200 User Manual

Command Line Interface

The Command Line Interface (CLI) is available on LAN1 and the Console RS-232 port.
The user can connect to LAN1 using SSH or TELNET. By default, SSH is on and TELNET
is off. Use the SERVICES - Startup web page to change these settings.
The username and login are the same as for the web interface.
Note: Physical access to the console port on the SyncServer should be controlled. The inter-
active bootloader could allow a malicious user to override boot parameters and gain restric-
ted access to the device. If more information is required, contact Microsemi Customer
Assistance (on page 3).
The CLI command structure has two levels: a top-level command set of system commands
and an intrinsic help command set. Commands are entered as ASCII strings typed at the
command prompt. The specific commands available at the particular tree level can be dis-
played by entering a "?" ("?" followed by "Enter" on the keyboard).
The CLI interface interprets the input on a character-by-character basis. As a result, only
enough characters to uniquely identify the command need to be entered for the CLI to recog-
nize which command you want to invoke. The CLI also accepts multiple commands on a
single line when they are separated by spaces, so you don't have to press Enter after each
command.
It is suggested that commands marked "Use all caps" be entered in all caps. This helps pre-
vent accidental entry of those commands.
The following Top-level, and Intrinsic Help commands are available from the CLI.
Top-level Commands
GPSSTRENGTH: (Status only) Displays the GPS satellite tracking information in the following
format:
N,X1,Y1,Z1,...,XN,YN,ZN
Defined as follows:
N = Number of satellites. If one or more satellites are available, Xi,Yi,Zi follows N.
n
X1 = Satellite vehicle number.
n
Y1 = Satellite signal strength in dBW where less than -200 dBW means no signal.
n
Z1 = Z1 can be either T or C:
n
T(racking) means the SyncServer receives the information from the satellite but
n
the information is not used in its timing solution.
C(urrent) means the SyncServer currently uses satellite information in its timing
n
solution.
For example, no satellites:
