I'd like you to imagine that you and I been invited to take
a tour of a corporate network.
So we go in and they take us to their data center.
And we look at the routers and switches and the servers
and the firewalls and the storage and have a good time.
And if they asked us, hey, what traffic
is going through our network?
How would we know?
It's tough to know.
And that's a good question for the network managers
themselves.
And to get a visibility, or to find out
what is actually coursing through the veins
of our networks, we need a tool that can do that.
And one of those tools is called NetFlow.
And that's what this set of videos WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And that's what this set of videos
is all about, about how NetFlow works,
the big picture, how it's implemented
in version 5, in version 9, and also version 10.
And then, also, to take a look at the pieces
that if it's not working correctly,
where we would go to look to troubleshoot it.
So that's what we have in store for us.
And I'll see you in the very next video
as we take a look at the big picture of NetFlow.
