If an organization has devices then to check all devices, one by one every day, are working properly or not is a hectic task.
SNMP is used to monitor the network, detect network faults, and sometimes even used to configure remote devices. Managed devices can be network devices like PC, routers, switches, servers, etc. This information is organized hierarchically. It consists of objects instances which are essentially variables. It is simply used to retrieve data from SNMP agents. In response to this, the SNMP agent responds with the requested value through a response message.
The SNMP manager can request data continuously until no more data is left. It is introduced in SNMPv2c. These devices can be routers and access servers, switches, hubs, computer hosts, IP telephones, printers etc. An agent is a software module residing within a device; it is executed at all times. This agent reports the information via SNMP to the managing systems. A network management station runs the network management protocol and the monitoring applications which provide the bulk of processing and memory resources required for network monitoring.
An SNMP network can have more than one network management station. Free Download. How to enable SNMP on your operating system. SNMP doesn't work!

Credentials for SNMP devices. No authentication is required and messages are not encrypted. For obvious reasons, this should only be used in closed, secure networks. Messages must be authenticated to be acted upon; however, they are not encrypted during transmission. Theoretically, a malicious actor could still intercept data that was sent between agent and manager during authorized transmissions but could not introduce additional Get or Set requests.
AuthPriv — Stands for Authentication and Privacy. This is the most secure implementation of SNMPv3. The SMI Structure of management information is a component used in network management. Its main function is to define the type of data that can be stored in an object and to show how to encode the data for the transmission over a network.
GetRequest: The GetRequest message is sent from a manager client to the agent server to retrieve the value of a variable.
This type of message is used to retrieve the values of the entries in a table. If the manager does not know the indexes of the entries, then it will not be able to retrieve the values. In such situations, GetNextRequest message is used to define an object. This message contains the value of a variable requested by the manager. SetRequest: The SetRequest message is sent from a manager to the agent to set a value in a variable. Trap: The Trap message is sent from an agent to the manager to report an event.
For example, if the agent is rebooted, then it informs the manager as well as sends the time of rebooting. JavaTpoint offers too many high quality services.
