SNMP Protocol

Level 4:
Example: If the SSU2000 has a GPS module installed and the module is locked
with satellites, it then has UTC time. The SSU-2000 is automatically an NTP
SERVER at Stratum Level 1. When the system (with GPS module installed and
UTC time) is a SERVER, it cannot operate as a client.
If the system is an NTP server, you can set your system for broadcast mode by the
commands:
NTP ADD BROADCAST XXX.XXX.XXX.255
Note: The broadcast mode only works with class C networks with no gateway.
Example: If your unit IP address is 172.16.18.20, then the broadcast mask may be
172.16.18.255.
Your system can be configured as a client (if you don't have a GPS module
installed) by the command:
NTP ADD CLIENT XXX.XXX.XXX.XXX
This is the most common mode to get timing packets.
If your system is not a server, it can also be configured as a broadcast client to
receive timing packets from a broadcast server by the command:
NTP ADD BCLIENT XXX.XXX.XXX.XXX
For more information on these and other NTP commands, refer to
Interface, on page 266, and
SNMP Protocol
This section describes the two versions of SNMP that the SSU-2000 supports. The
Communications module software determines the version of SNMP used by the
SSU-2000. See

SNPMP v2 Details

SNMP is based on a client-server query-response mode that requires an Ethernet
connection. A manager application (software installed on a computer) is the client
generating the queries, and an agent (software on the SSU-2000) is the server
generating responses.
