Greg, We are not running IOS-XR, however this is almost the same and I can set this up.
With the loopback0 interface setup what are the commands I need to run, so that I am monitoring this device correctly with netflow? Would it be: ip flow-export source loopback0 ip flow-export version 5 ip flow-export destination 172.20.200.50 Now I configure netflow for switched traffic: mls nde sender version 5 mls flow ip interface-full mls nde interface On the interface (loopback0): (Not sure if this is needed for the loopback interface?) ip route-cache flow Thanks for the help. ________________________________ From: Volk,Gregory B [mailto:[email protected]] Sent: Monday, March 08, 2010 11:50 AM To: Travis Formoso; [email protected] Subject: RE: [Flow-tools] Setting up NetFlow on 6509 > >What should the loopback interface look like? > Here's what one of mine looks like, but it requires some config integration with OSPF, assuming you're running OSPF. router#sho run int lo0 Building configuration...

What should the loopback interface look like? Also once I set it to this loopback I will not need to export to the VLAN's as this would monitor all the ports?

We have a number of different VLAN's across our network and I think I would want to monitor those VLAN's and that should capture the traffic on the 6509 (correct me if I am wrong.) The way the product is licensed is by source (a source is a router or switch.) When I try to setup netflow each VLAN comes in as a different source and I would like it if I can use the 6509 as just once source. Here are the commands I am using to set this up. in configuration mode: ip flow-export source vlan10 ip flow-export version 5 ip flow-export destination 172.20.200.50 Now I configure netflow for switched traffic: mls nde sender version 5 mls flow ip interface-full mls nde interface On the interface (vlan 10): ip route-cache flow After doing that I see that incoming traffic is being monitored by NetFlow, however as said that interface (VLAN) is coming in as a source, so if I configure another VLAN I now have 2 sources, but I would like to set this up so the 6509 is just one source, monitoring all the VLAN's. I wanted to know if these commands are correct, if I should be monitoring the VLAN's and if anyone knows how to set this up as explained above with the 6509 as one source. Thank you, Travis
