I have enabled netflow on a Cisco 1800 router. All the interfaces are showing inbound and outbound traffic apart from Fastethernet 0. It is showing Traffic for inbound only.
when I run show ip flow interface, I noticed that it created a subinterface for fastethernet0 even though I did not create it manually. Also sh ip cache flow is reporting traffic to be Local (not sure if this is of any relevance)
ittcrt03-perurt01#sh ip cache flow | inc Fa
Fa0 192.168.254.100 Local 192.168.254.26 2F 0000 0000 1

I recommend not using 'ip flow egress' and using 'ip flow ingress' on all interfaces on your router. Using netflow on egress is used only for several special cases, but normal configuration is 'ip route-cache flow' (deprecated command) or 'ip flow ingess' on all L3 interfaces. Do you using NAT?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
