FieldServer Driver - Ethernet
FS-8704-09
SNMP
Description
The SNMP driver allows the FieldServer to transfer data to and from devices over Ethernet using the SNMP version 1 protocol. The FieldServer can emulate either a Server (SNMP Agent) or Client.
The Client can be configured to read values specified by their SNMP Object Identifiers (OID’s), which are defined in the MIB file (Management Information Base) of the target device. When acting as an SNMP Agent (Server), the driver makes the contents of specified integer data arrays available to any SNMP Client. The FieldServer MIB file sets out the OID’s to use.
The current version of the driver can send and receive SNMP traps. The following SNMP data types are currently supported:
· INTEGER
· OCTET_STREAM
· TIMER_TICKS
· STRING
The maximum number of traps currently supported is 255.
The FieldServer Enterprise ID is 6347. MIB files are generated automatically from the FieldServer configuration files. A selection of standard MIB-2 OID’s are supported to allow interaction with popular Network Management packages.
