Roland,

I am aware of all disadvantages of this approach. But as soon as there 
is some DDoS going through respective box, it's netflow capacity is 
absolutely overwhelmed, thus not creating 'standard' flows.

The other major issue is that overwhelmed netflow on Sup2T causes the 
box to stop responding to SNMP queries.. :/


Thank you,


Jiri
