I am attempting to simulate multiple SNMP agents on my computer. I am using this software to try and accomplish this.

From the program's description:

Verax SNMP agent simulator is a tool that can simulate multiple SNMPv1/v2c agents on a single host on standard 161 port through multi-netting.

I am able to have one device up and running using the following type settings:

<type filepath="C:\vxsnmpsimulator\conf\..\device\os\os-linux-std.txt" state="stopped">
    <devices>
        <device ip="192.168.9.66" netmask="20" port="161"></device>
    </devices>
</type>

However, if I add a second device...

<types>
    <type filepath="C:\vxsnmpsimulator\conf\..\device\os\os-linux-std.txt" state="stopped">
        <devices>
            <device ip="192.168.9.66" netmask="20" port="161"></device>
        </devices>
    </type>
    <type filepath="C:\vxsnmpsimulator\conf\..\device\cisco\cisco_router.txt" state="stopped">
        <devices>
            <device ip="192.168.9.67" netmask="20" port="161"></device>
        </devices>
    </type>
</types>

I see the following message in my logs:

2012-06-19 10:58:16.339 ERROR [com.veraxsystems.SimulatorSNMPAgent.Agent ] Start agent [192.168.9.67/161]: Cannot assign requested address: Cannot bind 2012-06-19 10:58:16.339 INFO

I see numerous, commercial programs which advertise simulating 10-50,000 SNMP agents. I am wondering how they accomplish this if only one device is allowed to bind to 161.

I had read that when dealing with UDP it was possible to have multiple devices listen on the same port. This isn't the same as binding to the port, though, so I am not sure if that knowledge is applicable to this endeavour.
