SNMP Explanation

SNMP is also know as Simple Network Monitoring Protocol. It operates at the application layer in OSI Network Reference Model. 

SNMP Variable is constructed in a format defined by SNMP Protocol, therefore an access to data can be done. 

SNMP Variable name is consist of an IP Address with integer number fields separated by dots (decimal points or period). It have more than 1 fields found in the IP Address. 

MIB ( Management Information Base ) is the collection of variables or managed objects found in an SNMP device. It provides the complete hierarchy order of all managed objects in order to access the data. Variables are unique to a particular manufacturer's equipment must be located under the private enterprises branch of the ISO naming tree. Hence, every private enterprise OID will begin with 1.3.6.4.1.XXX , where XXX is the private enterprise number for the manufacturer that is registered. Private Enterprise Number is maintained by IANA. The entire and updated list can be found here: http://iana.org/assignments/enterprise-numbers.

OID is called as Stands for Object Indentifier. It is a string of numbers that defines the address of variable in MIB. 

SNMP Trap is the only form of SNMP message initiated by the SNMP Agent. It is most commonly used as an alarm notifications.
