A Simple Network Management Protocol port is a network communications channel. Administrative computers use SNMP to monitor equipment attached to a network. In an SNMP setup, a software agent constantly reports information about the network via SNMP to the administrative computer.
Human managers step in as needed to modify network settings. Equipment connected to a network can include printers, computer workstations and routers.
SNMP is part of the Internet Protocol Suite, a group of standards for managing networks. The standards for database setup and network management are created and managed by the Internet Engineering Task Force. SNMP is vulnerable to potential security issues, including interception of data and attacks against servers.
