Does anyone have basic information on configuring Netflow on routers/swtiches? We have several customer asking requeting us to send traffic to different destination servers. My curcuit is already at 75%. Will Netflow cause more bandwdith problem?
Here is the getting started configuration guide for Netflow on IOS routers -
Catalyst switches do things in hardware so not all support Netflow, depends on your switch models.
Netflow does add to the bandwidth obviously but it should not overload your link. It will also increase the use of resources on your devices so be aware of that as well.
