Simple Network Management Protocol (SNMP) is an internet standard protocol for managing devices
on IP networks. It is used to monitor network-attached devices for conditions that warrant
administrative attention.
An administrative computer (SNMP manager) monitors one or more DSE892 devices.
Each DSE892 monitors a number of DSE controllers using a variety of connection methods (detailed
elsewhere in this manual).
Should an ‘event’ occur, the DSE892 Gateway reports information via SNMP TRAP messages to the
manager.
Additionally, the DSE892 responds to GET / SET messages from the SNMP manager to allow the
host controller’s operating mode to be changed, or instrumentation values to be retrieved.
Many third party SNMP managers exist. DSE do not produce or supply SNMP managers.
