Hello and welcome back to I send you one interconnecting Cisco networking devices, Part one.
00:05
This episode a one for the Cisco Discovery Protocol Friend Erra Nova, instructor for this course US video went over the concepts of NTP and our configure it on the Cisco Devices.
00:16
In this episode, we'll be covering the Cisco Discovery Protocol and also the Link Layer Discovery Protocol.
00:23
You said we're gonna cover the Cisco Discovery public. We're going to take a look at it in our lab. And also we're gonna figure out how to configure the Linklater discovered protocol and take a look at it in the lab as well.
00:35
But first, what is some information that CDP will not give you? I'll give you a few seconds.
00:43
All right, Hopefully you got the NTP status.
00:48
I'll show you where you can find the rest of that information.
00:51
So he says, go to security protocol. I know you guys should have seen me use it a few times here and there. This is a Siskel proprietary protocol for layer to it was created before the standard for Linklater Discovery protocols there, man. Cisco decided to make their own before they're done.
01:07
Once again. It's just probably teary. It doesn't work well in a multi vendor environment
01:11
for Cisco Devices work phenomenally.
01:15
So have you seen the photo? We have the device I d. Which is the host name at the domain name. I realize now
01:23
I messed up the domain name for one of them again, like usual.
01:26
Ah. But anyway, it gives you the local interface that that device is connected to on on your local device. And we'll give you the capability of it, whether it a switch, a router, different devices and I'll give you the plant for my i d for it as well. As you see, I have a 29 60 switch
01:44
up top for a switch to on a router. One is an 18 41 rounder
01:47
and then also gives you the port I D. Of the remote port that is connected to using CT fast. Ethernet 0 24 is the port that the
01:55
switched to has it plugged into. And rather one has it plugged in a serial 000 as well.
02:01
I'm gonna go ahead and just bring out the party session to show you a couple of the commands again has always so versed will just do show CDP neighbors. It should bring up the same information that we see here
02:13
we have switched to on our fast Internet 00
02:15
It is a switch on the 29 60 platform and I plugged into the fast Ethernet 0 24 of the switch
02:23
and same thing rather one plugged into Sierra zero.
02:27
It's a router 80 14 or 18 41 platform and I'm plugged in a serial zero on that remote device.
02:34
One thing you can do here if you want to see the I p addresses of those information's gonna CDP neighbors detail. This gives you a ton of detail for each device,
02:44
so we'll just start up with switch one right here. We have
02:46
24 ports switched the actual full platform.
02:51
We have the interface that it is plugged onto on our local ports. We have the port that is connected to on the remote device.
02:59
We have the exact IOS software with the release information that that switch is running
03:08
and some other
03:10
advertisement efficient. One thing doesn't good to note. Here is the TTP domain, native villian and duplexes ever useful as well
03:20
and same thing with the router. One. We have the I. P. Address this time of what it sets, and we also have the I p version six I p addresses
03:28
the platform capabilities, the local and remote ports.
03:32
We have the software versions. Vtb domain. It's not said
03:38
so. CDP is very useful when figured out what is attached to your devices. And this one is very useful in the exams as well. If I remember correctly
03:49
anyway, we're gonna go ahead and move into the Link layer Discovery Protocol. This is the IEEE standard 802.1 a b. Uh, this was created after CDP. This is wonderful because it is the open standards. So it's multi vendor supported.
04:02
So what we can actually do? Let's say you're in a multi vendor network where you might have said in that gear,
04:08
switches and routers somewhere you might have some ubiquity stuff. You know, you just have multi vendor equipment.
04:15
So what we can do on our cisco switches? I'm gonna go and bring up party again.
04:18
First thing we're gonna do is we're in naval
04:21
The
04:24
l l d P so L L D P
04:30
All right,
04:33
all right. So actually, the switch to my switch The router that I have, it does not have LDP enabled for that IOS
04:42
a little too old to 29. 60 actually. Don't support l d. P. So I'm gonna go ahead and configure for that
04:47
configure terminal.
04:48
Well, dp
04:51
which can do run.
04:54
And from there, you have to have enabled on the interfaces. Well, so what I'm gonna do is I'm actually gonna plug in a,
04:59
uh, just a
05:00
crossover cable between the two switches. I haven't running right now,
05:04
and so that way we can enable it on those interfaces. So I'm just gonna go into interface F 0 22
05:12
Hello, dp?
05:15
Well, dp.
05:17
And what we're gonna do is we're gonna unable to transmit,
05:21
and we're also going to enable it to receive,
05:27
so we'll go ahead and plug in to switch to
05:34
All right, so we're gonna switch to configure Terminal where we have to enable it first.
05:40
Well, dp run, we're going to cafe is 22. Which is that Portland constant cable transport between the two switches.
05:49
So do l O
05:50
L d p transmits
05:55
well DP receive.
05:59
We'll give it a few seconds and we'll see if we can do a show command here.
06:02
All right, so we're gonna take a look at show CDP neighbors real quick.
06:09
So we do see the switch one.
06:12
And we're on remote fort phase over 22. So it's good.
06:15
So let's take a look at the show. L o d P here.
06:20
So we have active. So what? Marriage isn't able this time,
06:25
So let's go take a look at Show L L D P.
06:28
Neighbors
06:30
here, we have switched one local interface 22
06:34
remote port 22.
06:39
So if we also go in and we do details,
06:43
we get
06:44
basically the same amount of information as that's the CDP as well. So we're IOS version.
06:53
Um, the capabilities of the physical media. Auto negotiation is supported.
07:00
Um,
07:01
Disneyland one,
07:03
you know, So it doesn't say native land. One just has told you a TV line that you're currently on,
07:09
and so the virus is a similar. They're very good. The LDP is gonna work well in a multi vendor partner, environments where CDP works just fine and a cisco environment.
07:18
So again, we went over a CD. Pierre, the Cisco Discovery Protocol. We looked at how it's already enabled a Cisco Devices how it works in between the devices. And we looked at L. A DP and enable that are two switches. And we looked at how to what? The difference is in between the CBP and I will deep eating to be in that it's not a whole lot of difference and what I can actually show you.
07:39
So why would someone use L A d p over CDP? I'll give you a few seconds to think about it.
07:46
All right? Hopefully you got it works well in the multi vendor environments.
07:50
Uh, and no, just because it is newer does not mean that it is better. That is not true.
07:58
And Alexis and we're gonna look at the Cisco IOS management. We're gonna look at ah, doing so. File transfers with a c p r t f T p. We're gonna look at password cover. Finally, we look at the different Iowa's packages,
08:09
and as always, it is. Well, you guys have questions. Need help. Feel free to shoot the message. Otherwise, thank you for Washington. It's a lesson. I look forward to seeing. The rest. Um
