Installing SNMP on Linux Systems

SNMP, or Simple Network Management Protocol, is a crucial component for network management, allowing OpManager to effectively monitor and manage network devices. An SNMP Agent is a very small file that is installed on a network device. The agent collects and sends its operational data to an SNMP manager, for easy network monitoring and management. This help document will guide you through the process of installing OpManager's SNMP Agent on a Linux system.

The installation of new version of SNMP is required only for versions prior to 8.
