Template:FAQ:Agent 09
From Net-SNMP Wiki
Dynamically loaded modules are a means of including a MIB implementation module within the main SNMP agent (or an AgentX subagent) without needing to re-compile and re-link the agent binary. Instead, details of the module(s) to load are specified in the configuration file, and the agent locates the files listed, and merges them in at run time.
