Dear netflow users,

is there anyone out there with experience regarding nfdump and v9
flows from cisco routers? My boss recently found the Netflow v9 RFC
(found at http://tools.ietf.org/html/rfc3954), saw that it supports
VLAN information, and now wants to incorporate this information in our
traffic watch and accounting tool (which uses v5 at the moment).
Checking netflow_v9.c and netflow_v9.h with my limited knowledge of C
programming, it seems that the fields 58 and 59 aren't implemented
right now. So there arise two questions:
- How much work is it to implement this two fields?
- Are there any undocumented "Predefined element tags" to get access
on the implemented v9 data fields, beside the ones listed on the
documentation webpage?

Thanks fopr any information,
Jens
