I'm trying to implement Netflow on our SUP720 with "time sampled" option with following configuration:
ip flow-cache timeout active 1
mls flow ip interface-destination-source
mls nde sender version 5
mls sampling time-based 1024
sh mls sampling
Time-based Sampling is Enabled
1 out of 1024 packets is being sampled
Sampling Interval and Period is 8 millisec per 8192 millisec
ip route-cache flow
mls netflow sampling
I'm using the flow-tools to gather and store the netflow data on the disk and then export them into database.
The problem is that I get quite a lot of information in netflow datafiles, much much bigger as expected. It seems that the "time sampled" netflow exporting doesn't work and the whole netflow data are exported.
Is there any problems in my configration that can lead to this misbehaviour?
