SNMP Concepts and Configuration Article Description The Simple Network Management Protocol (SNMP) is a common site in most networks, it provides not only a method that can be used for event notification but can also be used to maintain device statistics, set configuration parameters and many other functions. In addition to information gathering, SNMP can be used to manage devices—for example, to shut down a network interface. This ensures the OIDs are returned in numerical format. At a minimum, to enable the service, set a Polling Port (Default is udp/161) and a Read Community String. SNMP provides a common way for devices on your network — such as routers, switches, WiFi access points, printers, and anything connected in an IP network — to share monitoring metrics. If the MIB files are not in the default Net-SNMP MIB directory, you may need to specify the full path, as in the following example. Does anyone have code examples for this sort of thing? Thanks!. The Simple Network Management Protocol (SNMP) is used to communicate management information between the network management stations and the agents in the network elements.
