SNMP Interface

The SNMP interface provides the possibility to monitor devices in the network with enabled SNMP interface. SNMP stands for Simple Network Management Protocol and can be used to control networking devices. Furthermore the devices enable to read and write information on them. The information of a SNMP device is based on a so called SNMP Management Information Base (MIB) (Management information base) Tree, which can be browsed over object identifier so called SNMP Object Identifier (OID). This OID's are strings like 1.3.6.1.1.3.1.0, that represent the item path in the MIB tree. Each number specifies another OID value of another node in the tree and enables to navigate to the required value. The SNMP standard provides standardized function which allows to read and write information on this values. SNMP devices have additionally the possibility to send so called TRAP messages if specific events happen. This allows systems which receive this messages to react on this events with further actions. The NETx BMS Core Server allows the definition of items that contain the separated information which is delivered by the device when the TRAP message is delivered.
