[c-nsp] Netflow Question

[raa at opusnet.com]

Hi,

Can anyone tell me the difference between the interface command:

Router(config-if)# ip flow ingress
Router(config-if)# ip flow egress

And 

Router(config-if)# ip route-cache flow

Thanks.  Second part to this question is anyone recommend a Netflow
analyzer?  Either application or appliance (price is important.)  I'd like
to get one where I can assign clients access where they only have access to
the ports I assign them.  I'm currently using the free version of
Scrutinizer.

Thanks all!
