Solution:

Network management systems use SNMP to monitor devices on the network for conditions that warrant administrative action. SNMP managed devices describe configuration and management information in the form of variables called Object Identifiers (OIDs). Management applications can query and sometimes set OID variables. OIDs are natively arranged in a numerical hierarchy, such as 1.3.2.11.11.4. A management information base translates the numeric OIDs into a more human-friendly format, such as SysName. A software component called an agent runs on the managed system and reports these variables to the managing system via SNMP through IP. Widely used and multivendor supported, SNMP is the de facto standard and most popular protocol for managing diverse networks. SNMP management capability is useful and important for all Ethernet networks, including EtherNet/IP applications. ODVA EtherNet/IP infrastructure guidelines require switches with both Web- and SNMP-accessible port status and diagnostics functions for large-scale control enterprise or networking. These functions are also recommended for all general-use applications.
