Configuring NDE on 4000 Series Switches


    Follow the steps below to configure NDE on a 4000 Series switches.

    Note The 4000 and 4500 series switches require a Supervisor IV or a Supervisor Engine V with a NetFlow Services daughter card(WS-F4531) and IOS version 12.1(19)EW or above to support NDE. Or you must have the Supervisor Engine V-10GE (the functionality is embedded in the supervisor engine).

    Configure this device as for an IOS device, but omit the ip route-cache flow command on each interface. Then issue the following command:

    ip route-cache flow infer-fields

    This command ensures routing information is included in the flows. You will not enter the ip route-cache flow command on each interface.


    A Sample Device Configuration

    The following is a set of commands issued on a 4000 Series switch to enable NetFlow version 7 and export to the machine on port 9996 using FastEthernet 0/1 as the source interface.

    switch>(enable)ip flow-export destination 9996
    switch>(enable)ip flow-export version 7
    switch>(enable)ip flow-export source FastEthernet 0/1
    switch>(enable)ip flow-cache timeout active 1
    switch>(enable)ip route-cache flow infer-fields
