Re: Snapshots of Sflow

Thanks for the anwer Elisa

Well i would like something similar to Netflow. There it is possible to
snapshots from how much traffic went to a certain as, without having a system
analyzing the info all the time.

From what you tell me this is imposible with sflow.

I would like to eliminate the need of a collector, and just have some sort of
resume as an snmp trap or some equivalent.
