SNMP Management Model
An SNMP managed network consists of two main types of component: agents and a manager. 
An agent is a management software module that resides in a managed device (the Device). An 
agent translates the local management information from the managed device into a form 
compatible with SNMP. The manager is the console through which network administrators perform 
network management functions. It executes applications that control and monitor managed 
devices. 
The managed devices contain object variables/managed objects that define each piece of 
information to be collected about a device. Examples of variables include such as number of 
packets received, node port status etc. A Management Information Base (MIB) is a collection of 
managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing 
these objects.
