Chapter 46 Configuring NDE
Additional NDE Fields
You can configure NDE to populate the following additional fields in the NDE packets:
•
•
•
These fields are populated by the software looking up the FIB table entry before sending out the NDE
record to the collector. Therefore, these fields are blank when you use the show command to display the
hardware NetFlow table.
NDE Versions
NetFlow version 9 is supported and is described at this URL:
http://www.cisco.com/en/US/docs/ios/12_3/feature/gde/nfv9expf.html
NDE exports statistics for NetFlow aggregation flows using NDE version 8. The following document
describes the version 8 header format:
http://www.cisco.com/en/US/docs/ios/12_2/switch/configuration/guide/xcfnfov.html
NDE exports IP unicast traffic using NDE versions 5, 7 and 9.
Some fields in the flow records might not have values, depending on the current flow mask. Unsupported
fields contain a zero (0).
With the WCCP Layer 2 redirect, the nexthop field and the output field might not contain accurate
Note
information for all NetFlows. Therefore, the destination interface for traffic returned from the web server
has a client interface instead of the cache interface or the ANCS interface.
The following tables describe the supported fields for NDE versions 5 and 7:
