For this hands-on lab, here's what I'd like you to do,
pretty much mirroring what we did in the videos up to this point.
I'd like you to configure NetFlow,
flexible NetFlow specifically on R2 using the following.
I'd like you to create a flow record called
our-flow-record and I want you to match on three things.
IPv4 protocol, IPv4 source IP address,
and the IPv4 destination IP address.
Then once you have that flow record created,
I'd like you to create a flow exporter named
our-flow-exporter with the destination server of 2312100 WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
our-flow-exporter with the destination server of 2312100
and a source of loopback 0 and the UDP destination port of 996.
Now, it doesn't matter whether or not we actually have
a functional NetFlow collector at that IP address,
but I want to make you familiar with how to configure it.
The reason I'm doing it in this order is because when we go to
the flow monitor, which is our third step,
it's going to ask for, "Hey,
which flow exporter are we going to use,
and which flow records are we going to use?"
I'd like you to create that our flow monitor as the third step,
including the user-defined exporter and record that we created, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
including the user-defined exporter and record that we created,
and then apply that inbound on gig 0, 0,
gig 1, 0, and then gig 2, 0.
Once that's done and you've generated some traffic to go through the network,
and a good way to do that is to go to the Windows 11 client-nug machine
and just ping, for example,
33333 or 4444 or ping the server itself,
and the NetFlow cache should show that.
To see the NetFlow cache, you just come in and show,
"flow monitor", the name of the monitor, and then the keyword cache.
And as far as a little bit of help in the lab, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And as far as a little bit of help in the lab,
there's also a document on Server 1 regarding NetFlow.
It's a text document.
You can open it up, and that also has the commands to implement this
if you need a little bit of help or you want to peek at that configuration.
So have some fun with the hands on that,
and when you are done with it and ready for a walkthrough,
join me in the next video and we'll do that together.
