I have about 250 Cisco Routers in my network all running the same IOS Version 124-15.T4 and 249 of them are working for NetFlow to a NetQoS server pulling the data. I have the same configuration set up on this router having the NetFlow issues and I'm still not able to pull any NetFlow after issuing a "sh ip cache flow"
I have ip route-cache flow enabled on all of my interface with IP Addresses on them and have the following lines of config included as well.
ip flow-cache timeout active 1
ip flow-export source FastEthernet0/0.1
ip flow-export version 5
ip flow-export destination 172.18.11.144 9995
The above commands are the same on all of my other 249 routers and are reporting NetFlow with no problems. Any suggestions that could help me diagnose why this single router won't render any NetFlow please?
