Disabling NetFlow
The following example shows how to disable ingress NetFlow for an interface labeled “GigabitEthernet0/0.”
myrouter#configure terminal
myrouter(config)#interface GigabitEthernet0/0
myrouter(config-if)#no ip flow ingress To disable egress NetFlow, use the ip flow egress interface subcommand as follows: myrouter(config)#interface GigabitEthernet0/0
myrouter(config-if)#no ip flow egress
NOTE: Ingress NetFlow is the most commonly used method. Egress NetFlow is more commonly used with MPLS VPN. The MPLS Egress NetFlow Accounting feature allows you to capture IP flow information for packets undergoing MPLS label disposition (i.e. it captures packets that arrive on a router as MPLS packets and are transmitted as IP packets). Egress NetFlow accounting might adversely affect network performance because of the additional accounting-related computations that occur in the traffic-forwarding path of the router.
