We have entered an era where everything is evolving into the digital world and in such a way, the dependency on computer networks is increasing drastically. Consequently, many more automated tools are being developed for various purposes to help get rid of the manual management of networks for good. Computer networks are now larger than they ever used to be, therefore, they require proper tools for management. Cisco is one of the most dominant names in the networking field and the routers produced by them always intend to surprise. NetFlow is a feature that was first introduced in Cisco routers which helps you monitor and collect the incoming and outgoing traffic on your network. Such a network protocol cannot be neglected in today’s world and are extremely helpful in the management of a network.
