Netflow nfsen

[Xyue]

Hi guys,

I have installed the nfsen and I'm able to access it through http://localhost/nfsen/nfsen.php

http://meefirst.blogspot.sg/2014/05/installing-nfsen-1612-on-centos_27.html

I have configured below command in my switches:

SW(config)#ip flow-export destination "nfsen_server_ip" 9995
SW(config)#ip flow-export version 9
SW(config)#ip flow-source gi1/1/1
SW(config)#int gi1/1/1
SW(config-if)# ip flow ingress
SW(config-if)# ip flow egress

However, I cant see anything from the nfsen.
Can anyone please advise any steps did i missed ?

Thank you very much in advance.
