• (NN event averaging): Should always display 1 event average.
• NN.NNN ns: Measurement results.
• XXXXXXXXXX S: The second (from 1 Jan 1970) when the average was computed.
• NNNNNNN uS: The fractional second the average was computed. This value plus the
number of seconds provides the time stamp when the average was computed.
• sd: 0.00000 ns: Standard deviation should always be ZERO.
3.4.4 File Transfer Protocol (FTP)
Allows users to upload a new software version (.iso) and use the software_update command to
update the system software. The ftp user can get to the SNMP MIB files using the change
directory command (cd mibs) and has read permissions but is unable delete the files in the mibs
subdirectory.
3.4.5 Simple Network Management Protocol (SNMP)
The ATS-6501 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 ATS-6501 retrieves the desired system information and provides it to the
NMS.
The Management Information Base (MIB) files describe the structure of the management
data of a device subsystem and are stored on the ATS-6501 in the MIBS subdirectory of the
FTP directory. They can be retrieved from the unit via a FTP client (username: ftp, password:
ftp). An example from a ATS 6501 .mib file is shown below.
