[c-nsp] Netflow sampling rate configuration?

[Joe Loiacono]

Well, for IOS versions 12.2SX you must first set the flow-mask to 
interface-full via:

>mls nde interface

then ...

>mls sampling packet-based 128

128 is the closest option to 1 every 100 packets per flow.

Good luck. The documentation is confusing to begin with, and then 
considering different IOS's makes it worse.

Hi Guys,

I'm using IOS 12.2(14r)SZ1.
~From IOS 12.2, is there any way to set sampling rate for netflow data?
I would like to collect 1 netflow data per every 100 flow.
I tried to check ip flow-export options, but no option for setting
sampling rate for net flow data export.
Thanks in advance.

Hyun
