Hi Gurus of Cisco.
I am in a project to monitor some KPI on my some routers, We have a SNMP tool, and recently we bought a features of Netflow to integrate to this managment.
Ours routers in average has peaks of 40% of consume of CPU
If for example I enable this functionality
router#enable
Password:*****
router#configure terminal
router(config)#interface FastEthernet 0/1
router(config-if)#ip route-cache flow
router(config-if)#exit
router(config)#ip flow-export destination 192.168.9.101 9996
router(config)#ip flow-export source FastEthernet 0/1
router(config)#ip flow-export version 9
router(config)#ip flow-cache timeout active 1
router(config)#ip flow-cache timeout inactive 15
router(config)#snmp-server ifindex persist
router(config)#^Z
router#write
enable on both interface (FastEthernet 0/0 and FastEthernet 0/1)
My doubt is, The CPU processing would be grow?. Enable this feature will be damage the performance of the Routers (CPU, Memory, more traffic on his interface).
Please, let me know.
I hope your comments / Suggestion
