3.4.3 Network Time Protocol (NTP)
Network Time Protocol (NTP) is provided for the dissemination of time to other devices on the network.
The NTP structure classifies devices based upon levels referred to as stratums. Stratum-1 indicates a clock
that is obtaining time from a reference clock. The 4380A NTP server is a stratum 1 server. To check the
status of the internal NTP Server telnet into port 1700 and use the
status reference:ntp
command. locked =
true indicates the system is providing accurate time, false indicates it is not. The source should indicate that
it is using the internal reference clock. The 4380A is capable of supporting ~100 NTP Clients.

3.4.4 Simple Network Management Protocol (SNMP)
The 4380A includes an SNMP agent to provide external monitoring of system status via a Network
Management System (NMS) . The agent provides the ability to get status but does not provide SNMP trap
or set capability. SNMP is a protocol used by devices to share system information with a SNMP NMS
responsible for monitoring the status of multiple devices. When polled by the NMS the 4380A retrieves the
desired system information and provides it to the NMS.
The system supports SNMP Version 3 and the community string (-c) is tsc.
The Management Information Base (MIB) files describe the structure of the management data of a device
subsystem and are stored on the 4380A in the MIBS subdirectory of the FTP directory. They can be
retrieved from the unit via a FTP client (username: ftp, password: ftp)
3.5 Status Command
The 4380A provides overall system status, health, and measurement results via the
status
command
available on the command port (1700). For more detailed information and a description of the fields refer
to Appendix B.
Status provides a sequence of field names to distinguish various devices and information from one another.
Each information field has a unique ID. Users can display the entire set of data fields using the
status
command. It is possible to further refine the data requested by adding additional information fields to the
command line. For example, if the user simply wanted to get the information on this system type
status
unit.

Users can further refine the requested data fields by adding the desired information line to the field to look
for specific data. If the user wanted to look for the system uptime, the user would simply add a “:” then the
sub-category under unit. Additional subcategories can be added to the command line, separated with the
“:”.
