    Unmanaged Interface VoIP-Null0:

    Don331

       With the latest Orion and Netflow, we keep seeing the infamous

      "NetFlow Receiver Service [SWORION01] is receiving a NetFlow data stream from an unmanaged interface on 172.16.10.58. The NetFlow data stream will be discarded. Please use the Orion System Manager to add Interface #11 in order to process this NetFlow data stream"  error message.


      We traced down the interface, and they are all coming from in interface named  VoIP-Null0:

      If we go back to the Node resources in Orion, there isn't any interface by that name to add.

      But the router command shows it:

      Jacksonville-gw#show snmp mib ifmib ifindex
      FastEthernet0/0: Ifindex = 1
      Foreign Exchange Station 0/0/0: Ifindex = 14
      Loopback0: Ifindex = 26
      Null0: Ifindex = 12
      VoIP-Null0: Ifindex = 11

       Any ideas?

          Hi Don,


          Did you try rediscovering the device in Orion?

              Andy,

               

              Yes, I did - no interface by that name

                  Next I'd try a MIB walk on that device to see if there is anything strange in the IF tables.

                      Mib-walker doesn't show that interface for some reason:

                      lubbock-gw#show snmp mib ifmib ifindex
                      FastEthernet0/0: Ifindex = 1
                      Foreign Exchange Station 0/0/0: Ifindex = 14
                      Loopback0: Ifindex = 26
                      Null0: Ifindex = 12
                      VoIP-Null0: Ifindex = 11
