even the best sampling mode interval might not good enough. It doesn't come
down to which GSR you have but on which linecard you want netflow enabled.
The performance differs between Engine 0,1 and 2 cards. With the engine 0
card, even sampling at the highest rate might still cause you to loose 20%
of the linecard forwarding capabilities.
We had a GiGe card that we used netflow on , sampled 1/100. When we removed
it, the same night we went from our normal average 690 MB to 780Mb.
What type of linecard engines do you use?
