I have Cisco 6500 switch which is sending netflow data to Orion server from all of its physical and virtual interfaces. Switch is added to Orion with management VLAN address (VLAN1, 192.168.100.1). Orion gives this event notification:
NetFlow Receiver Service [SERVER111] is receiving a NetFlow data stream from an unmanaged device (10.10.10.1). The NetFlow data stream from 10.10.10.1 will be discarded. Please use Orion Node Management to manage this IP address in order to process this NetFlow data stream, or just use Manage this device.
Why's that? Is it because the server is in 10.10.10.1 subnet and gets netflow data from same VLAN? Sounds logical, but do I really have to manage the device twice (and all interfaces!) to get also VLAN10 traffic data without this event message? To pay the element license twice?!? I think it's stupid...
Changing node IP in Orion doesn't sound good either, because then I'd see switch in wrong IP address in NCM. It should show with same address as every other switch in this LAN, management address is of course the natural way to see switch with NCM. Any suggestions for this? How to get rid of this unpleasant detail...?
And what this means: "The NetFlow data stream from 10.10.10.1 will be discarded..."
No it isn't! As far as I know, I'm getting VLAN10 data without any problems. Or do I miss something...?
Backgroung information:
VLAN1, 192.168.100.1 = switch management vlan
VLAN10, 10.10.10.1 = office vlan
SERVER111 = Orion server, NPM, NTA & NCM.
Netflow source = Catalyst 6500, about 100 interfaces
