How to avoid NetFlow sampling

As resource demands and bandwidth speeds in many of today’s network infrastructures continue to increase, many network administrators believe that NetFlow sampling is the only way to deal with the high flow volume sent across the network. In fact, setting a NetFlow sample rate of 1 in 100 can cut flow volumes as much as 50%.

vSphere Configure Netflow

Today we are going to take a look at how to configure NetFlow so that you can gain visibility into your vSphere virtual distributed switches. Efficient traffic management requires usable and relevant information from all points on the network. Collecting NetFlow provides an efficient means to identify inappropriate behavior, problems and discrepancies.
