Network Administrators and Engineers need to obtain statistics for their network infrastructure, while SNMP does a great job at this it by providing us broad information such as packet count, interface changes, and device health, it cannot provide us granular information about our networks. This is why Cisco introduced NetFlow, a tool that works alongside SNMP by letting us obtain information and statistics for the unique types and characteristics of data flowing through interfaces. In this post I will discuss how to fundamentally implement NetFlow and concepts revolving around it.
