Agent Helpers

Net-SNMP Agent Helpers

The Net-SNMP agent library provides several special purpose Handlers to reduce the work needed to implement a MIB module. See the Agent Architecture documentation for details on how the handler system is implemented within the Net-SNMP Agent. The FAQ item "What's the difference between the various mib2c configuration files?" gives an overview of the major mib2c-related helpers.
