We had situations, that we lost all our bgp sessions, not even only on 
ports where flood was coming. Just cpu overloaded. I don't care about 
support too much, there are cheap enough to have spare. Soft is mature 
with known bugs so i assume that this risk are accepted. Bigger problem 
for me is technical details about features, which i desribed in my first 
post. Most of this features i tested on trident2 chipset extreme 670, it 
works but with problems and some limits. Now i have to change vendor. 
Really wondering what can i get from N3K-C3064PQ, its also build on 
trident2 AFAIK

thanks for answers,
Pedro
