SNMP Configuration
An agent is a management software module that resides in a managed 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 manager and
agents to communicate for the purpose of accessing these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a
request and the agent returns responses using the following protocol operations:
Get
Allows the manager to retrieve an object variable from the agent.
GetNext
Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1,
when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed
by a series of GetNext operations.
Set
Allows the manager to set values for object variables within an agent.
Trap
Used by the agent to inform the manager of some events.
