This is a followup to Multiple Different Snmp Agents in Single JVM.  I had fixed the initial problem by implementing the following code in the SnmpAgent constructor.  I have three SNMP Agents that I need to start up in a single JVM due to a requirement on the software we are designing (thus the simulation manager product recommended in the last post will not work).  For purposes of this post I will call them XX1SnmpAgent, XX2SnmpAgent, XX3SnmpAgent.

Each agent is setup using a virtual IP address:
XX1SnmpAgent: 192.168.189.50
XX2SnmpAgent: 192.168.189.71
XX3SnmpAgent: 192.168.189.80

The first thing I did was to setup a new constructor which looks like the code below:

1. public XXXSnmpAgent(String[] args, String addr, String dir) {
         super(addr, 8001);
         // This takes care of the options
         this.agentOptions = new AgentParamOptions(args);
         AgentUtil.setAgentDir(dir);
         AgentUtil.setLoggingParameters(6, "." + File.separator + "logs" + File.separator + "xxx");
         XXXSnmpAgent.agentDir = dir;
         XXXSnmpAgent.ipAddress = addr;
          
         Thread th = new Thread(this);
         th.start();
   }

The next think was to setup the TrapListener as such:

1.         trapListener = SnmpAgentInitializer.getTrapListener();
           /* User code starts here */
           trapListener.setLocalAddress(ipAddress);
           trapListener.setAgentAddr(ipAddress);
           trapListener.setUsesSeperateSession(false);
           /* User code ends here */

However two issues that need to get fixed and am requesting help on:

• Traps come out from a single IP address, my guess is the last SNMP session intialized.  I have tried to set the setUsesSeperateSession to true in the above code, however then the SNMP agents stop responding to requests.
• Logs are output into a single log file after all agents have been initialized.

My guess is the two issues reside from the SnmpAgentToolkit's use of Static Classes and a Cache, but I really need to find away to fix those two things.

Hello,

When starting up more than one SNMP agent using reflection on different ports, no network activity is able to pass from the mib browser to the agents and all requests times out.

Upon startup, I set the log directories to the specific directories for the agents.  I also set the IP Address to their respective ports.

Any ideas?
