FIGURE 8-1Using atmsnmpd as a Forwarding Agent

Note –If you do not specify a forwarding port for unknown requests, atmsnmpd will respond with a “No Such Name” error to requests for MIBs that it does not support. If you do specify a forwarding port, atmsnmpd instead forwards the request to that port. Responses received from the agent running on the forwarding port are sent to the requesting SNMP manager with no modification. If the agent does not respond, then atmsnmpd does not send a response back.

SNMP and Solaris

The ATM SNMP agent in SunATM supports a framework for SNMP agents; however, this means that its setup depends on the version of the Solaris operating environment in which it is running. This section discusses those differences, which are mostly transparent to the user.

Solaris 2.6, Solaris 7, and Solaris 8 Compatible Software

The Solaris 2.6, 7, and 8 operating environments include a bundled SNMP agent that is designed to run as a master agent, binding by default to UDP port 161. Configure other agents to listen to other UDP ports and act as subagents, then configure the master agent to forward particular requests to those subagents. This framework provides a single agent at port 161 with the combined capabilities of the master agent and all the additional subagents.
