Hey Jon,

I did what you said this morning and set this up as follows:

mls netflow
mls flow ip full

mls nde sender version 5

ip flow-export source Vlan20
ip flow-export destination 172.20.200.51 XXXX

interface Vlan110
 ip route-cache flow
!
interface Vlan200
 ip route-cache flow

When I went to the server that has the software for Flow it has a source
of 172.20.142.3 (which I am not sure what that is, but that is just the
source so it should be OK.)

There is no incoming traffic (is that the way it should be?)

And the outgoing traffic is 4235 flows per minute and collecting data
which is cool :P

So right now I just see outgoing traffic and none incoming, but should I
be monitoring both?

Also as far as monitoring the VLANS, should I monitor between VLAN14
(firewall) and VLAN200 or keep it between VLAN110 and VLAN200?

Thanks everyone appreciate the help, we are getting their.

The version and PFC / MSFC versions will matter as well. If you have
access, the Cisco docs explain this far more succinctly than I can.
