The Master Agent receives SNMP requests from the system managers and sends responses to these requests, after determining appropriate values from the subagents. The subagents provide management of different components based on the Management Information Base (MIB) specifically designed for such components/applications. Each subagent, when invoked dynamically, registers with the Master Agent. During registration, it informs the Master Agent of the MIB subtree it manages. For more information, refer to Chapter 3, SNMP-Based Master/Subagenton page 3-1.
The SEA technology provides a software development kit that allows you to create, release, and install subagents. Additionally, the SEA allows you to integrate and use SNMP-based legacy agents.
