What is Counter64?
Counter64 is similar to Counter32, except the range is now (0 to 18446744073709551615). This type may only be used when a 32-bit counter rollover could occur in less than an hour. The Counter64 value has 64 bits (unsigned long in Java). …
What is Gauge32?
Gauge32 represents a non-negative integer, which holds at the maximum or minimum value specified in the range when the actual value goes over or below the range, respectively. The string value should only be in decimal. …
What are the different data types used in SNMP?
RFC1155 defines the following valid SNMP data types:
- Primitive types: INTEGER, OCTET STRING, OBJECT IDENTIFIER, NULL.
- Constructor types: SEQUENCE, SEQUENCE OF.
- Defined types: NetworkAddress, IpAddress, Counter, Gauge, TimeTicks, Opaque.
What is SNMP MIB?
SNMP MIB. MIB stands for Management Information Base and is a collection of information organized hierarchically. These are accessed using a protocol such as SNMP. MIBs are collections of definitions which define the properties of the managed object within the device to be managed.
What are the two types of objects in SNMP?
Managed objects, in SNMP, are of two types : scalar objects and tabular objects. A managed object that always has a single instance is called a scalar object. Tabular objects, on the other hand, have multiple instances, such as the rows of a table.
What is RFC1213 MIB?

What is OID in SNMP?
In the Simple Network Management Protocol (SNMP), OID means an “Object Identifier.” To define OID, it’s an address used to uniquely identify managed devices and their statuses. If you’re a professional responsible for your organization’s large-scale network management system, read on.
What is the difference between OID and MIB?
The raw data (e.g. hardware temperature) is called an ‘object’ that resides within the device in a database, i.e. Management Information Base (MIB), and every object (the device statistics that you are trying to poll) is uniquely identified with an object identifier i.e. OID.
What are MIBS in SNMP?
A management information base (MIB) is a database used for managing the entities in a communication network. Most often associated with the Simple Network Management Protocol (SNMP), the term is also used more generically in contexts such as in OSI/ISO Network management model.
How do I get OID?
To obtain a fully registered OID at no cost, apply for an OID under Internet Assigned Numbers Authority (IANA) maintained Private Enterprise arch. Any private enterprise (organization) may request an OID to be assigned under this arch.
How do I get SNMP OID?
Take the following steps:
- Download SNMP Tester and unzip all files on your machine, preferably the computer on which you are running a PRTG probe (local or remote).
- Start SNMP Tester by running snmptest.exe.
- Select the Local IP for the server on which you would like to look up the OIDs, or leave Any.
