In our previous article we have discussed the alternative way to get flow statistics using a NetFlow generator. One of the fundamental features of the generator is its capability to export flow records to multiple destinations (NetFlow collectors). Often, it is...
What is a NetFlow Generator? A NetFlow generator is a dedicated network appliance or software running on a PC and listening on a single or multiple network interfaces (NICs). NetFlow generators create NetFlow records aggregating packets into flows based on the...
This is the second part of the post dedicated to NetFlow configuration. In the first part, we’ve discussed the configuration of Flexible NetFlow on Cisco IOS device and the configuration of j-Flow v8 on Juniper vSRX security appliance. In this part we will go further...
One of our recent blog posts dedicated to NetFlow technology provides the necessary knowledge needed to understand NetFlow principles and what it is used for. The post also explains differences across different vendor implementations of NetFlow, such as NetFlow,...
Flow-based (NetFlow, IPFIX, NetStream) and packet-based (sFlow) network monitoring technologies enable network administrators to gain insight into traffic traversing a network. They provide various statistical information such as top talkers, applications in use,...
