0:00:13	The next IP service topic that we have here is
0:00:16	NetFlow which is used to collect information on
0:00:19	traffic flows that are either leaving the router's interface
0:00:22	or entering the router's interface.
0:00:26	So if we wanted to collect usage statistics of how
0:00:29	much bandwidth is being used and what are the different
0:00:32	applications that are being used like how much of our
0:00:35	flows are web traffic versus FTP or peer-to-peer file sharing
0:00:39	applications, that's what NetFlow is going to be used for.
0:00:44	Now in order to actually sort through the data, it then implies
0:00:47	that we need to export this to some external collection station.
0:00:52	So the NetFlow configuration on the router is fairly straightforward
0:00:56	the only thing we need to do is tell it to collect the statistics
0:00:59	either in or out of the interface, then specify where we actually
0:01:04	are going to send this to which is the IP flow export destination.
0:01:08	Now before exporting the flows, we would need to know
0:01:13	what is the particular version that the collection station supports
0:01:17	where typically this is going to be either version 5 or 9
0:01:21	but it depends on the NetFlow collection station itself.
0:01:26	So within the scope of the routing and switching exam
0:01:29	if you were to get a question on this, again you should be able
0:01:31	to piece it together based on the documentation and
0:01:35	these different types of information like what is the
0:01:37	version, what is the destination, this stuff
0:01:39	they would simply have to specify in the question.
0:01:44	Now we can also do class based NetFlow sampling
0:01:48	which would allow you to do separate manual
0:01:52	sampling flows based on the module of the quality of service
0:01:55	or a flow sampler map, so if I wanted in my MQC
0:02:00	to say look at a particular web flow from a source to a
0:02:03	destination, match that in an access list and then apply
0:02:07	the NetFlow sampler to it
0:02:11	otherwise, I could apply it just on the interface level
0:02:13	with the IP flow egress and the IP flow ingress.
0:02:16	Another useful feature for this is to check the
0:02:19	statistics locally where if you don't have an
0:02:23	actual collection station you can configure the router
0:02:26	to keep the NetFlow data local, then you can sort through
0:02:30	it to figure out who are the noisiest talkers in the
0:02:34	network, so who are the sources and destinations that are
0:02:36	sending the most traffic which is known as the
0:02:40	NetFlow top talkers feature.
0:02:43	But for most of this configuration if you go to the documentation
0:02:48	this is going to be under the NetFlow documentation
0:02:53	itself, so it has a separate configuration guide.
0:02:57	If we look at the configuration guides, this would be configuring
0:03:00	NetFlow and Netflow export.
0:03:02	And I don't believe the top talkers is located in this
0:03:10	document, so this one is talking about just how do you collect the
0:03:13	statistics and then where do you send it.
0:03:17	So if we look at the configuration examples, it says example configuring
0:03:21	egress NetFlow accounting, so simply at the link level
0:03:24	we say ip flow egress
0:03:28	so it's only one command.
0:03:31	For incoming traffic, we say ip flow ingress
0:03:34	then to figure out where do we actually want to send
0:03:36	it, the ip flow destination, typically the port is going to be 9991
0:03:43	You can specify that if the collection station is using
0:03:46	a non-standard port or by default it's going to be using
0:03:49	UDP 9991
0:04:00	For some of the advanced features you can track traffic based on the
0:04:04	BGP autonomous system
0:04:06	so if you're used as a transit AS, you can figure out where
0:04:09	the most, the majority of your traffic is coming from.
0:04:13	Typically this is used for service providers to
0:04:15	negotiate their peering agreements
0:04:17	to see how much traffic is coming from one provider versus another.
0:04:23	MPLS enabled NetFlow
0:04:25	would be doing statistics based on the label values
0:04:29	because in the transit path of an MPLS network, we
0:04:32	can't do classification based on IP.
0:04:34	We'd have to do it based on the MPLS label value.
0:04:40	Then again, the other one that's useful here is the
0:04:42	NetFlow top talkers.
0:04:45	So if we look at simply the configuration example for this
0:04:58	this is using SNMP, that's not what I want to see.
0:05:03	Configuring NetFlow top talkers
0:05:09	Once NetFlow is on in global config we say ip flow top talkers
0:05:13	what's the number of statistics that we want to keep
0:05:17	so how many entries do we want to keep, then do we
0:05:20	sort it by the number of bytes or the number of packets.
0:05:28	So let's look at an example of this here on Router 5
0:05:32	where it's used for the transit of anything going to
0:05:34	switch 2 and switch 4 towards the rest of the network.
0:05:40	So on our connection to the frame relay interface
0:05:42	which is serial 0/0/0
0:05:47	I'll say that I want to collect NetFlow stats for flows that go out
0:05:53	and flows that come in.
0:05:57	If I don't want to set these to a flow, the ip flow export
0:06:04	destination, so again this would be for an external
0:06:07	collection station
0:06:12	otherwise, I'm simply going to enable the local feature which
0:06:14	is going to be the NetFlow top talkers.
0:06:18	So I'll say ip flow-top talkers
0:06:26	how many entries do I want to keep?
0:06:29	Let's say I'll keep the top 10
0:06:31	I want to sort this by the number of packets.
0:06:39	So now let's send some traffic through the network let's say
0:06:41	from switch 2 I'll start pinging Router 1's loopback
0:06:47	from switch 4 I'll telnet over to
0:06:53	let's say to Router 6
0:06:55	telnet 150.28.6.6
0:07:02	Then once we're on Router 6 we'll say show tech support
0:07:04	is going to generate a bunch of telnet traffic.
0:07:08	So now from Router 5 if we look at the show ip flow
0:07:11	top talkers
0:07:15	we can see the traffic is coming from the 58.100 address
0:07:19	which is actually what we allocated through DHCP previously.
0:07:25	It tells us what the IP protocol number is
0:07:29	which protocol number 1 is going to be for our pings.
0:07:35	Then we have packets coming from 108.10 going to
0:07:39	150.28.6.6
0:07:43	which this protocol number here this is in hex
0:07:48	so protocol number 58
0:07:50	if we said 58 in hex
0:07:53	is actually 88 in decimal which means it's EIGRP
0:07:58	So we could see that routers 1 through 4 are running EIGRP
0:08:01	destination interface is null it means it's going locally to the router
0:08:05	itself.
0:08:08	Then the source IP or the source port and the
0:08:11	destination port these are in hex as well.
0:08:14	So we can see destination port 17 in hex
0:08:21	I said 17 in decimal is 23
0:08:26	So you could potentially use this locally. It's obviously
0:08:29	not going to be as detailed as the information that you can
0:08:31	send to an external collection station, but this is used for
0:08:36	if you're trying to track down some sort of
0:08:38	maybe denial of service attack in the network
0:08:40	or there's some sort of worm or virus that's infected
0:08:44	hosts, then you can simply enable NetFlow in and out the
0:08:49	interface, turn on top talkers and then you're
0:08:51	going to know who is sending either the most number of packets
0:08:55	or the most number of bytes.
