Cisco 6509 - Configure Netflow

Hi All,

We have Cisco Netflow enabled on 2 1G WAN Interfaces on the Cisco 6509. But the problem is we dont see all the data being captured in the netflow. Because we see the link is utilized like 50M/sec but the statistics capture is very very low. Below is what we have configured in our Cisco 6509.

mls flow ip full
mls nde sender version 5
ip flow-export source Loopback0
ip flow-export version 5
ip flow-export destination 10.88.69.10 2055

interface GigabitEthernet5/1
ip address 10.88.87.1 255.255.255.0
no ip redirects
ip flow ingress
ip pim sparse-mode
spanning-tree portfast
end

interface GigabitEthernet6/1
ip address 10.88.88.1 255.255.255.0
no ip redirects
ip flow ingress
ip pim sparse-mode
hold-queue 2000 in
end

Also in our Solarwinds Orion i am receiving flow from all our VLAN's including the 2 WAN ports we enabled them for. Did we configure anything wrong? And we are seeing the CAM tables are full.

Thanks

im pretty sure you need a command netflow something established 1

this will send the cache data of flows in progress, not just the ones after they have ended, eg copying an iso across the network.

ip flow-cache timeout active 1 this should fix it, this will take the information it knows about after a min regardless of if the session is still ongoing
