I have downloaded an evaluation copy of Netflow 5 and currently testing it on 2 Cisco 2811 routers with 2 Ethernets and 1 serial WIC.
On the first router Fa 0/0 and S0/0 are showing the IN and OUT traffic while Fa 0/1 is only showing the IN traffic On the second router Fa 0/0 is showing the IN and OUT traffic while Fa 0/1 and S0/0 are showing only the IN traffic.
I understand that Netflow by default works in ingress mode so how come some interfaces are showing the IN and OUT traffic.
