Listening on multiple network interfaces ---------------------------------------- Q. I need my receiving entity (CommandResponder or Notification Receiver) to listen for SNMP messages on multiple network interfaces. How do I do that with pysnmp? A. Simply register multiple network transports with your SNMP engine. Each transport would be bound to an individual local transport endpoint (for instance, IP address & UDP port pair). .. code-block:: python # Security setup would follow ... # Setup first transport endpoint config.addSocketTransport( snmpEngine, udp.domainName + (1,), udp.UdpSocketTransport().openServerMode(('127.0.0.1', 162)) ) # Setup second transport endpoint config.addSocketTransport( snmpEngine, udp.domainName + (2,), udp.UdpSocketTransport().openServerMode(('192.168.1.1', 162)) ) # Receiver callback function implementation and Dispatcher invocation # would follow ... Notice extended transport domain specification (udp.domainName) in the code above. There we register each transport endpoint under distinct OID, however always within the canonical transport domain OID.
