Issue
Wanting to use SNMP to be able to create alarm traps from the network
Product Line
EcoStruxure Building Operation
Environment
StruxureWare Building Operation site
Cause
Simple Network Management Protocol (SNMP) is an "Internet-standard protocol for managing devices on IP networks. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more. SNMP is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention such as an alarm in StruxureWare Building Operation.
Resolution
For SNMP to be able to create alarms from the network in StruxureWare Building Operation, beginning with Building Operation 1.3 - StruxureWare Building Operation supports an older version of this service which uses the default community password. As such, the decision to open this port should be done based upon a risk/benefit assessment. The only form of SNMP that is currently supported is the ability of SmartStruxure to respond to the network management queries that might be issued by an SNMP client.
Through release 1.5, SNMP is only supervising the equipment and can not receive traps from SNMP. Beginning in the 1.6 release, you can send SNMP traps from an alarm. In future releases it may be able to export alarm traps to SNMP, but this is really an IT function. Release 1.6.1 introduces support for SNMP alarm traps v3.0 notifications. This requires an add-on option on for the corresponding server, either the Automation Server and/or Enterprise Server.
