Cisco 6509 Catalyst

Version 1

    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

     

    Then configure NetFlow for all the switched traffic:

         mls nde sender version 5
          mls flow ip interface-full
          mls nde interface
          mls aging long 64
        

    Finally, configure individual interfaces:

    ip route-cache flow
    ip flow ingress
