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...
Current configuration : 128 bytes
!
interface Loopback0
description *** MANAGEMENT & OSPF ID ***
ip address 10.130.25.1 255.255.255.255
ip pim sparse-mode
end
router#

ation/guide/hc3loop.html ...may help, but it's for IOS-XR.

Hey Greg,
On the 6509 there is currently no loopback interface so I will
need to set this up.
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?
Thanks

Have you tried setting the source to a non-vlan (physical or
loopback) interface like:
ip flow-export source Loopback0
I don't know if that will fix your issue, but I always source my
netflow data from a loopback interface that is dedicated for management
traffic.

Subject: [Flow-tools] Setting up NetFlow on 6509
Hello all,
I am trying to setup a NetFlow product on our 6509. 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
