Although it is recommended to use only a single Snmp instance with one or more TransportMappings, you can also use a single TransportMapping instance with more than one Snmp instance.
You probably need to implement your own MessageDispatcher then, to properly dispatch incoming messages to avoid timeouts because a response is processed by a different Snmp instance than the instance that sent the corresponding request.
When using the DefaultUdpTransportMapping you also need to call
transport.setAsyncMsgProcessingSupported(true); |
before
transport.listen(); |
or
snmp.listen(); |
To avoid parallel access to the transport mappings message buffer.
