Hi,
I'm trying to capture an ingress traffic on SVI interface of my Cisco 6506 (WS-C6506-E).
I've enabled NetFlow on the Multilayer Switch Feature Card (MSFC):
ip flow-export source Vlan254
ip flow-export version 5
ip flow-export destination 172.23.100.21 2055
Enabled NetFlow and NetFlow Data Export (NDE) on the Policy Feature Card (PFC):
ip flow ingress layer2-switched vlan 130
mls netflow interface
mls flow ip interface-destination
mls nde sender version 5
mls aging fast threshold 127
mls aging long 1000
mls sampling time-based 512
mls cef error action reset
mls netflow sampling
and on the monitorable interface:
interface Vlan130
ip address 172.23.170.2 255.255.255.0
ip flow ingress
mls netflow sampling
standby 1 ip + timers + priority + preempt + authentication
Now I'm trying to see capruted flows. The point is I can't see flow's source address, source and destination port, and L4 protocol for unicast flows:
Cat6506-LAN1#sh mls netflow ip

The same output info I get on my NetFlow collector.
Anybody know a reason what can prevent of collecting flows correctly?
Thanks.

might want to change the flow mask to full instead of destination. I think that should give you the rest of the info. chris
