SNMP or Simple Network Management Protocol


SNMP is a simple tool for Network Management. As networks grow larger, they become harder to manage. For this reason, SNMP has been devised. It
provides a systematic way of monitoring and managing a computer network.

          The simplicity is the strength of SNMP. This protocol allows managers to communicate with agents inside devices to read out their status and issue commands to them.   

          SNMP is designed to operate in both the TCP/IP and OSI environment. It is widely implemented in commercial products.

          SNMP has disadvantages that include functional deficiencies and a lack of security facility. Due to this, SNMPv2 and SNMPv3 are defined which are improved versions of SNMP. SNMPv2 contains a number of functional enhancements and provides good security features. SNMPv3 provides authentication, privacy and access control.

          The SNMP model of managed network consists of four components: -

                           (1) Managed nodes
                           (2) Management stations
                           (3) Management protocol
                           (4) Management information.
