The Master Agent, snmpdx, is the main component of Solstice Enterprise Agent (SEA) 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 by the service management facility smf(5) at boot time if svc:/application/management/snmpdx is enabled (see NOTES) and contents of the resource configuration file /etc/snmp/conf/snmpdx.rsrc are non-trivial.
Note -
The SMA (Systems Management Agent) is the default SNMP agent in the Solaris operating system. See netsnmp(5). snmpdx is Obsolete and
may not be supported in a future release of Solaris.
OPTIONS
The following options are supported:
-afilename
Specify the full path of the access control file used by the Master Agent. The default access control file is /etc/snmp/conf/snmpdx.acl.
-cconfig-dir
Specify the full path of the directory containing the Master Agent configuration files. The default directory is /etc/snmp/conf.
-ddebug-level
Debug. Levels from 0 to 4 are supported, giving various levels of debug information. The default is 0 which means no debug information is given.
-h
Help. Print the command line usage.
-ifilename
Specify the full path of the enterprise-name OID map. This file contains the PID used by the Master Agent for recovery after a crash. It contains tuples of the UNIX process ID, port number, resource name, and
agent name. The default file is /var/snmp/snmpdx.st.
-mGROUP|-mSPLIT
Specify the mode to use for forwarding of SNMP requests.
GROUP
Multiple variables can be included in each request from the Master Agent to the subagents. This results in, at mose, one send-request per agent.
SPLIT
Each variable in the incoming request results in one send-request to each subagent.
The default is GROUP.
-ofilename
Specify the full path of the file containing the tuple (enterprise-name, OID). For example, (Sun Microsystems, 1.3.1.6.1.4.32). The Master Agent uses this file as a base for look-up in the trap-filtering and
forwarding process. The default file is /etc/snmp/conf/enterprises.oid.
-pport
Specify the port number. The default port number is 161.
-rfilename
Specify the full path of the resource file to be used by the Master Agent. This file stores information about the subagents that the Master Agent invokes and manages. The default resource file is /etc/snmp/conf/snmpdx.rsrc.
-y
Set a recovery indicator to invoke the recovery module. The recovery process discovers which subagents in the previous session are still active; those subagents not active are re-spawned by the Master Agent.

ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
The snmpdx service is managed by the service management facility, smf(5), under the service identifier:
svc:/application/management/snmpdx
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command.
