Overview

The SNMP driver implements the server- and client-side of the SNMP protocol. It supports SNMP V1, V2 and V3. On the one hand, server items can be mapped to SNMP data points that are accessible by foreign SNMP clients via their Object Identifiers (OIDs). In addition, server item value changes can sent to foreign SNMP client via SNMP traps.

On the other hand, our driver can be used to integrate SNMP data points from one or more SNMP capable devices.

SNMP data points are addressed via their OID. SNMP communication is possible in two ways:

  • data point polling: The NETx Server cyclically sends SNMP read requests in order to get the current value of an SNMP data point.

  • traps: The NETx Server's SNMP interface receives SNMP traps sent by the SNMP device.

The driver is available for free. Each defined SNMP data point decreases the available licensed data points by one.

Installation

The SNMP driver is provided as an extension and is not included within the default setup.

To install the SNMP driver, open the Core Studio and shutdown the Core Server. Afterwards, start the Extension Manager via the menu Extensions > Manager > Start Extension Manager ....

Within the dialog, select "SNMP" and press the Install button. After having installed the SNMP driver, close the BMS studio and reopen it. Within the menu of the Core Studio you will find a new menu, SNMP. It contains items for all definitions that are necessary for configuration the SNMP driver.
