In SNMP, we represent each entity of information using object and to identify each object uniquely, we use OID (Object Identifier).
Now there is another terminology – MIB. I know it stands for "Management Information Base". However, I am not able to understand the concept of the term MIB.
Below is the image which represents the pictorial representation of object hierarchy tree-
rttMonCtrlAdminTag, rttMonCtrlAdminRttType, rttMonCtrlAdminFrequency represents Objects and corresponding OIDs are
.1.3.6.1.4.1.9.9.42.1.2.1.1.3
.1.3.6.1.4.1.9.9.42.1.2.1.1.4
.1.3.6.1.4.1.9.9.42.1.2.1.1.6
In this pictorial representation what does MIB represent?
Best Answer
The MIB is the entire catalog of OIDs (for a particular device).
An OID is a specific reference to an individual item within the MIB.
An analogy: The MIB is like the phone book for my city. The OID is like my name in the phone book.
