    Turn on netflow for the Catalyst router:

         ip flow-export source (interface name)
          ip flow-export version 5
          ip flow-export destination (netflow collector IP) (port exported flows go to)
          ip flow ingress layer2-switched vlan (any needed vlans)

         ip flow-cache timeout active 1

          mls flow ip interface-full
          mls nde interface
          mls aging long 64

    Finally, configure individual interfaces:
