Is it possible to pull data from this router?
I'm trying to ensure that we have everything set up. Source is loopback0. I have destination/port point to Orion server. However, no NetFlow traffic is being detected when we pull via Orion.
Any ideas?
We are pulling data via NetFlow now. We had to change the source to the Gig Ethernet interface. Now, that is working.
Here is my 3840 config
!interface GigabitEthernet0/1 description OLD IP'S FROM THE 10.6.0.0 ROUTER !!!!!!!!!!!! ip address x.x.x.x 255.255.255.224 ip accounting output-packets ip mtu 1438 ip flow ingress ip flow egress ip route-cache flow ip tcp adjust-mss 1350 duplex auto
ip flow-export source GigabitEthernet0/0ip flow-export version 5ip flow-export destination 172.17.100.112 2055!
gotta have the ip flow
to add to the great information that mstevens wrote, you may not recieve data comming from the loopback. you may recieve an event with in solarwinds stating some thing like netflow receiver service is receiving a netflow data stream from an unmanaged interface on (ip address).
if you want to use the loopback interface as the source address for all exported traffic flows from the router then you may need to add in a command into the CLI
ip flow-export source loopback0
depending on the IOS version that you are running this command may not be available.
if its not availible you can edit your node that you want to monitor and track info with netflow to have the same IP address.
I wanted to use netflow, but I set up my nodes using the loopback address. So netflow saw the stream comming from the interface closest to my server, I then edited my node to use that IP address of the interface. This may work for your senerio,
The ip flow-export source is loopback0.
It has a IP assigned to it. We're seeing the traffic hit the collector, but it is from an unmanaged device. We can only add via ICMP, which negates the purpose...because we're not getting the traffic.
I can't add the node/interface via the IP for the loopback0 interface on SNMPv3. Is there a way to get around this? I talked with support and they don't have much to offer on this issue.
I can't be the first guy to run into this problem.
I have a 3845 and am successfully pulling data via NetFlow. Have you insured the correct NetFlow version on your router? Mark Stevens' reply clearly shows his configured for netflow version 5. SolarWinds only supports version 5 in the current version (not V3).
