SNMP is an Internet standard protocol used for managing network devices running TCP/IP, using a manager-agent model where a manager monitors and controls agents running on devices. It uses three components - SNMP itself, SMI which standardizes object attributes, and MIB which defines the set of objects supported by each network device for SNMP management. There are three versions, with v1 having poor security and v2 improving on performance, security and confidentiality over v1.
