This section describes how to retrieve SNMP information from the CMS appliance.
A Management Information Base (MIB) is a text file written in a specific format in which all of the manageable features of a device are arranged in a tree. Each branch of the tree contains a number and a name, and the complete path from the top of the tree down to the point of interest forms the Object Identifier, or OID. The OID is a string of values separated by periods, such as .1.3.6.1.2.1.1.3.0.
You can send requests for data on an object using the OID, but it can be simpler to use the symbolic name for the object instead. A MIB allows SNMP tools to translate the symbolic names into OIDs before sending the requests to the managed device. Symbolic names for objects in the Trellix MIB include feSerialNumber.0, feHardwareModel.0, feProductLicenseActive0, feFanIsHealthy.1, and so on.
The Trellix MIB, named FE-FIREEYE-MIB, needs to be downloaded from the CMS appliance to the SNMP manager so it can be loaded into an SNMP browser or other tool. A typical SNMP browser can retrieve the values the appliance supports, and then display them in a hierarchy so you can navigate to the value you need to include in the request.
