MPLS-aware netflow

[mirta.majic]

Hello,

I have P router (7206VXR) and I need to export netflow from its MPLS interfaces to the netflow software.

I use these commands:

ip flow-export  source Loopback0

ip flow-export  version 9

ip flow-export  destination x.x.x.x 9995

ip flow-cache timeout  active 1

ip flow-cache timeout  inactive 15

ip flow-cache mpls label-positions 1 2 3

int g0/1.3

encapsulation dot1Q xxx

ip address x.x.x.x

ip flow ingress

ip flow egress

no snmp trap link-status

mpls label protocol ldp

mpls ip

mpls mtu 1512

service-policy output xxx

I get certain ammount of traffic on my netflow software, and also with

sh ip cache verbose flow

But this is far away from the heavy production traffic that is going on this link.

How to get complete netflow traffic from this interface? Any idea is appreciated.

Thanks.

If I am correct, netflow shows current flow in terms of bytes/sec or packets/byte per protocol

and total of those, still in seconds time lapsed...and its burst.

I don't think its an accumulated value.

Can you post actual bandwidth use? Traffic log in your netflow analyzer and router ip cache flow result?

..say stat for top 2 talkers?

Hello,

thanks for your reply.

Netflow analyzer shows complete bandwidth usage in a form of graph or pie chart. From this graph you read or drill down to individual flows.

Actual bandwidth use in my case is about 1M inbound. In my netflow analyzer I can read only 100k of routing protocol traffic.
