In the last column, the MIB name can be defined. The MIB name parts must be equal to the parts of the OID – the parts are separated by “.”. E.g. if there is an auto generated OID (OID is left empty), the MIB name is a single entry (e.g. sensor1). If the OID suffix is 1.10, the MIB name must contain two parts. E.g. device1.sensor1).
| Note |
|---|
Keep in mind that the MIB names must be consistent and unique. Check the server logs for warnings or errors after loading the configuration. |
The Core Server automatically generates an MIB file. This file can be give to the SNMP clients to show the correct names. The location of the MIB file is:

<WorkspaceFolder>\LogFiles\NETx.mib |
An example
Consider the following SNMP mapping definitions:
...
The OID of the first data point is generated automatically. Assuming that the default base OID is used, the full OID of definition 1 is 1.3.6.1.4.1.58651.1. The MIB name is iso(1).identified-organization(3).dod(6).internet(1).private(4).enterprise(1).netxautomation(58651).sensor1(1).
The second data point uses a specific OID suffix. Assuming that the default base OID is used, the full OID of definition 2 is 1.3.6.1.4.1.58651.2.1 The MIB name is iso(1).identified-organization(3).dod(6).internet(1).private(4).enterprise(1).netxautomation(58651).device1(2).value1(1)
| Note |
|---|
Note that a suffix of 1.10 for definition is not valid. This would result in an OID of 1.3.6.1.4.1.58651.1.1 which is not allowed since the first definition already uses 1.3.6.1.4.1.58651.1. |
The result MIB file looks as follows:
