I'm interested in Netflow Data Export (NDE) performance on the DFC3CXL:
does it have the same NDE performance as RSP720 or is it more like SUP720?
The DFC3XL does not do NDE. This is done by the RP on the RSP720 / SUP720.
Actually, as I understand it in certain configurations the NDE packets
can be generated and emitted by the DFC CPU. As I recall, certain
netflow options and/or masks prevent this from happening, and require
the RP CPU to either modify the NDE packets which the DFC CPU generates,
or generate the packets itself.
IIRC things like src/dst AS number and other things you'd expect the RP
to know, but the DFC to not, come into this category.
