[Pysnmp-dev] Pysnmp: Can't receive trap when set privacy protocol as AES

[chengkeke <che...@16...>]

Hi All,

I have an issue: I can't receive trap when set v3 user privacy protocol as AES. I can receive the trap when set it as None and DES.
Could you please help me on it? Thanks a lot.
snmp trap command: snmptrap -v3 -u read -l authPriv -a MD5 -A 12345678 -x AES -X 12345678 192.168.0.10 "" .1.3.6.1.4.1.XX.2.2.1.1 1.3.6.1.4.1.XX.2.2.2.18 s "00:24:82:2D:A3:33"
Here is the code of add v3 user: [set it as config.usmAesCfb128Protocol]
  snmpEngine = engine.SnmpEngine()
    
    host = '192.168.0.10'
    port = 162
    # Setup transport endpoint
    config.addSocketTransport(
        snmpEngine,
        udp.domainName,
        udp.UdpSocketTransport().openServerMode((host, port))
        )
    print 'UDP service [%s:%s] is open' % (host, port)
    
    # v1/2 setup
    config.addV1System(snmpEngine, 'public', 'public')
    
    # v3 setup
    config.addV3User(
        snmpEngine, 'read',
        config.usmHMACMD5AuthProtocol, '12345678',
        config.usmAesCfb128Protocol, '12345678',
        #'\x80\x00\x1F\x88\x80\x72\x12\x67\xFD\x4D\xF2\x4F\x07',
    #   '\x80\x00\x4f\xb8\x1c\x3d\xaf\xe6'   # ContextEngineID of
                                             # Notification Originator
        )
    
    print 'V3 User created successfully'
    
    # Apps registration
    ntfrcv.NotificationReceiver(snmpEngine, cbFun)
    snmpEngine.transportDispatcher.jobStarted(1) # this job would never finish    
    snmpEngine.transportDispatcher.runDispatcher()
