Video Description
VLAN Trunking Protocol Lab In this last lesson on Layer 2, Data Link layer, we return to our VLAN simulation and select four switches that represent each of the three VTP modes, 1 for Server Mode, 1 for Client Mode and 2 for Transparent Mode to demonstrate how VLAN Trunking Protocol relays VTP advertisement. You'll learn how to correctly configure each switch to the VTP mode and once configured, you'll observe the output readings that provide a status on each switch and learn what data is the most important to focus on.
Video Transcription
00:04
We're looking at art apology again. What's which? One switched to switch three and switch for
00:10
I'm going to make switch one. The BTP server.
00:14
I'm gonna make switch to and switch three btp transparent
00:19
to see if they really do. Really? Every TV advertisements
00:22
and I'm gonna make switch four into a V T p client.
00:26
So let's go in to log in to switch one
00:29
whips.
00:30
It's not removed these links by accident,
00:39
and I'm going to say B t p
00:42
mode. And if I execute the health future by pressing
00:47
hitting question Mark,
00:48
I see three options client server and transparent.
00:51
I'm gonna make switch one the service which,
00:55
when I do that, it's a device mood already BTP server. So by default, all Swiss co switches are V t p server mode switches.
01:06
Next,
01:07
I'm gonna create a V t p domain
01:11
and it's asking for
01:14
a word.
01:15
So I'm going to save e t p domain ccn, eh?
01:19
Now, all cysts, all switches in your network. If you're using BTP must be in the same domain. If they're not, they're not going to talk me tp with each other.
01:30
Next, I'm going to set of E T p password
01:34
we t p password. And let's just keep it at Cisco.
01:42
So the device
01:45
villain database password has been changed to Sisko.
01:49
Now let's look at our work. Do show we t p
01:55
status.
02:00
Now a few things that you want to pay attention to in this command,
02:04
the most simple one is of course, the operational operating mode is
02:09
your V t P
02:12
mode ISS server.
02:14
The domain name has been changed to see CNN.
02:20
Now, if I were to ask you what version off BTP you're running here, where's in one overs in two.
02:27
You might be tempted to say that I'm running version, too, since it say's BTP version, too.
02:35
However, if you look down here, it says v tpv to mode disabled.
02:40
So you're actually running version one?
02:45
If I say
02:46
BTP
02:49
version
02:51
two
02:53
and then execute the do show V t P
02:58
Status command again.
03:00
Now you see, vi tpv to mode is enabled. Now, I actually am running version, too.
03:06
Before I was running version one, so don't get caught by that on the test,
03:12
I'm gonna disable
03:14
BTP version two again.
03:16
I'm gonna go back to version one
03:20
and if I execute the command show BTP status you see that V tpv to mode is now disabled.
03:30
Now, what about this field? The configuration revision
03:35
The configuration revision is account
03:38
off How many changes that have been made to really land on dat file. So
03:45
once again, the configuration revision is account of the changes you have made to the villain dot that file.
03:52
Let's see,
03:53
I will add. Right now, the configuration revision is six. Because since we started this class, we have made six changes to the villain dot That file
04:01
I'm gonna add Villain 123 threw the switch
04:09
and exit out of there. So that is one additional change we made new show
04:15
Retief. Well, let's see if the villain has been created for a new show reel and brief
04:20
and well, and 123 has been created with a default name of Villain. 123
04:26
And let's look at our configuration revision. Do show BTP
04:30
status
04:31
and it went to seven.
04:33
So it implemented by one. Since I made one change to the villain dot dat file,
04:40
let's take away that. Be that no real man. 123
04:44
once again remember that to negate a command in Cisco or to do the opposite of a command and Cisco, you simply add a no in front of the command. You pretended that command with a no
04:56
and I hit. Enter. Let's look at our new show, BTP Status Command again.
05:00
And once again, since I deleted the villain, that constitutes another change to re land on that file.
05:09
And the configuration revision has incriminated 28
05:13
The last
05:14
change I made
05:15
with BTP. We're setting a password and I don't see a password being shown here. That is, by design.
05:23
To see the password, you actually have to execute the command. Do show BTP
05:29
password
05:31
and you see that the V T P password is set to Sisko.
05:36
Now I'm going to go to switch to
05:42
and make it a V T p transparent switch.
05:45
So we tp mood transparent.
05:50
Then I say we tp domain.
05:55
I believe it was C c N A.
05:57
And you see, the doorman has already set to see CNN
06:00
since switch to and switch three by default already. BTP servers switch one, sent out the domain name in BTP advertisements and switch to accepted it
06:12
I'm going to set the V t p password
06:15
to Sisko that
06:18
you actually have to set manually. That does not propagate over for security purposes.
06:26
And now I'm gonna look at my do show V T. P Status Command,
06:32
and my domain name is C C N A.
06:35
My operating mode is transparent, and my configuration revision is actually zero
06:44
avi tp transparent Moz, which has its configuration revision set to zero because the configuration revision, as a said, is account of the modifications made by the server switch to the villa. And on that file, however, a transparent switch does not participate in V T. P.
07:02
It only realized BTP information.
07:05
Hence the configuration revision, which is a count of the number of changes made to the villain dog. That file on the server switch
07:14
is set to zero.
07:15
Let's look at our password. Do show V t p password
07:20
and it is set to zero. Always check your work as you're doing it.
07:26
Don't leave it for later. Because then you don't know what command you did that caused the error.
07:31
I'm gonna go to switch
07:32
three
07:36
and do the same. Make it of e t. P. transparent switch BTP mode
07:46
transparent.
07:48
I'm gonna set the password
07:51
to Sisko.
07:55
And just to make sure
07:58
I'm gonna set the domain
08:00
Chiu c c n a.
08:03
Now I'm gonna go to switch for and turn it into a client
08:09
with the same password
08:11
and domain names or btp domain CCN, eh?
08:16
BTP password Cisco. I go ahead and type the domain name anyways because I don't trust
08:22
it to automatically propagate over. And it's good practice
08:28
and re tp mode
08:31
transparent.
08:33
I'm gonna check my work. Do you show BTP
08:37
status?
08:41
Whoops. I was supposed to set this to
08:43
client, so let's set it to client.
08:50
Okay, so now, once again, check my work. See, It's a good thing since I caught my own mistake.
08:56
So the operating mode has been set to be TV mode client
09:01
and the domain name is CCN, eh? Let's check the password. Make sure
09:05
it matches. We tp password? No.
09:09
Do show BTP password.
09:15
And the V t P password has been set to Cisco at this time. Switch for should only have villain 1 50 Do show villain
09:26
brief.
09:28
So as we see, we only have the land 1 50 it is applied to Port 24.
09:35
I'm gonna go check. Switch one.
09:41
Do show, villain
09:43
brief
09:45
and switch One also only has villain 1 50 The same should be true for switch to and switch for
09:52
now. Let me go ahead and create villain. 777
09:58
777
10:00
And I'm gonna name it. Test.
10:05
I'm gonna exit out of this mode and make sure this villain was created. So do show reel and grief.
10:11
And yes, 777 is active with the name test.
10:16
Now switch
10:20
too. And Swiss tree are transparent mode switches. So they should not have created villain 777 on themselves.
10:26
So let's make sure they didn't
10:30
do show reel and brief
10:33
And no, I do not see the land 777 on switch to Since it is a transparent mode switch, it is a transparent switch.
10:41
Let's go to three and do the same check.
10:46
Do show villain brief
10:50
and no, I don't see the land. 777
10:54
I only see the villain 1 50
10:56
and this should be correct. Since which three is a transparent switch
11:01
on Let's go check Switch for
11:05
this one should have created the land 777 cents. It is a client switch, so let's check. Do show.
11:13
Freeland
11:15
Brief
11:16
and Dillon 777 has magically appeared on switch for Not Magic.
11:22
BTP
11:24
carried Villain 777 in BTP. Advertisements from Switch one True Switch to and switch three to switch for.
11:35
So switch forwards a client switch and listen to the villain over TTP advertisements
11:41
from Switch one and created Real and 777
11:45
Now what happens if I try to create villain? Let's say 55 on switch for Let's Try it,
11:52
Leland 55
11:54
and it says. VT TV Land configuration not allowed when devices in client mode so the client cannot modify its villain dot dat file. Last little tidbit.
12:05
Well, let's see if I can create Real and 5551 a transparent switch
12:11
or real and 55 on a transparent switch. So switched three is a transparent mode switch.
12:18
We land 55
12:20
and sure enough, it created it.
12:22
Let's check, usually land brief
12:26
and we land. 55 is here,
12:30
so
12:31
no, we land 55 I want to get rid of it,
12:37
and it should have gone away.
12:39
But since a transparent mode switch does not participate in BTP. It is allowed to add and create and adding to lead its own villa. It can modify the be land on that file
12:50
Now. Last little tidbit
12:54
on switch one. We were checking our
12:56
V t p status. Do show V T p status.
13:01
I'm scrolling through my command using the up and down arrow key.
13:07
No.
13:09
What is the difference between BTP version two and version one?
13:13
The only difference is and I believe it could be asked on the test. That version to supports token ring villains,
13:22
So V t p version to supports token ring.
13:26
So this villain 1003 used for token ring the token ring default We land version one
13:33
does not support token ring. Version two does.
13:37
I'm gonna go ahead and save my work. And this concludes
13:41
the V t p section
13:43
of the class.
13:45
The end
