The OID identifies managed objects that can have assigned values

What terms are defined in the MIB?

The elements defined in the MIB can be extremely broad (for example, all objects created by private businesses) or they can be extremely specific (like a particular Trap message generated by a specific alarm point on an RTU.)

Each element in the MIB is given an object identifier, or OID. An OID is a number that uniquely identifies an element in the SNMP universe. Each OID is associated with a human-readable text label.

What is the function of an OID?

The OIDs identify the data objects that are the subjects of an SNMP message. When your SNMP device sends a Trap or a GetResponse, it transmits a series of OIDs, paired with their current values.
The location of the OID within the overall SNMP packet is shown above.

What does an OID look like?

Here's an example: 1.3.6.1.4.1.2681.1.2.102
