You need flow export version 5 on your routers to use cflowd.  It sure
would be handy if the error message that cflowd printed lead you
believe this instead of that your IP stack is broken somehow.

In addition to version 5 of the export format, newer IOS versions also
let you do good things like expire flows more frequently then 30
minutes (the old default) and set the source address.
