The Master Agent, snmpdx, is the main component of Solstice Enterprise Agent technology. It runs as a daemon process and listens to User Datagram Protocol (UDP) port 161 for SNMP requests. The Master Agent also opens another port to receive SNMP
trap notifications from various subagents. These traps are forwarded to various managers, as determined by the configuration file.
Upon invocation, snmpdx reads its various configuration files and takes appropriate actions by activating subagents, determining the subtree Object Identifier (OID) for various subagents, populating its own Management Information Bases (MIBs), and so forth. The Master Agent invokes
subagents, registers subagents, sends requests to subagents, receives responses from subagents, and traps notifications from subagents.
The Master Agent is invoked from a start-up script at boot time only if contents of the resource configuration file /var/snmp/conf/snmpdx.rsrc are non-trivial.
