NTA 3.10 Not displaying flows

sdawson35

Hi,

We have NTA 3.10 running on top of Windows server 2008 R2, we have 2 Cisco 6506-E's configured to send netflow, but when selecting say a vlan we get "Data is not available"

We have changed the collector port to 9996 in "Netflow Settings"

Sample config

ip flow-cache timeout active 1

ip flow ingress layer2-switched vlan 15-22,30-32,115-122,130

mls aging long 64

mls aging normal 64

mls netflow usage notify 90 120

mls flow ip interface-full

no mls flow ipv6

mls nde sender

mls qos

no mls acl tcam share-global

mls cef error action freeze

interface Vlan2

description *** Server VLAN ***

ip flow ingress

ip flow-export source Loopback0

ip flow-export version 5

ip flow-export destination 172.26.5.150 9996

Hi Scott,

In your example config, does your Vlan 2 have an IP address assigned?  I was told once that this is required, but I haven't had a chance to test it.  But I have seen it not work on a switch port, but does work on the associated VLAN.

Also, I assume you can send flows from other routed ports on this switch and NTA does process it.

Thanks,
