Simple Network Management Protocol (SNMP) is a standard protocol specifically designed to manage network nodes (servers, workstations, routers, switches, and hubs) in IP networks, which is an application layer protocol.SNMP (Simple Network Management Protocol) is based on UDP port 161, which uses UDP port 162 for the management station.

SNMP is an internet standard protocol that can be used to manage devices on an IP network ". Generally, devices that support SNMP include routers, switches, servers, workstations, printers, modems, and more devices. It is most commonly used in the network management system to monitor devices connected to the network. Pay attention to the situations that require the Administrator's attention. SNMP

Simple Network Management Protocol (SNMP) is a standard protocol used to manage IP network devices. Typical SNMP-enabled devices include routers, switches, servers, workstations, printers, and data cabinets. SNMP is generally used by the network management system to monitor additional network devices according to the conditions set by the Administrator. SNMP is an integral part of the Internet Protocol Suite, which is
institutions. It contains a series of network management standards, including an application layer protocol, a database architecture, and a set of data objects.
SNMP displays management data in the form of variables, which describe the system configuration. These variables can also be used to manage application queries (or set ).
