As you see, I've pulled out.
I've pulled out the lab again,
I have already done the housekeeping configurations that we did on Router One for switch one. So we're set to go switch one already has a name, which is s W one. As you see,
with the prompt and we already in privilege mode, we are going to create a villain 1 50 I'm gonna minimize switch one for a second. So we're going to create villain 1 50 Where? My curse serous when my mouse is right here on switch one, and then
we're gonna add villain 1 50 to port 24.
Support 24 on switch one is connected to a router ones port 00
The reason we're doing that
is access links are usually connected to end devices,
a PC would be an end device.
A router in this case is also going to act as an end device.
So Router one is gonna go
into villain one. I mean, Router one is going to go into villain 1 50 which means we need to put port 24 off, switch one into villain 1 50
already. So I'm in switch one.
by executing configure terminal or convict T
and then to create villain 1 50 Remember, we just simply say villain 1 50
and I go into conflict villain mode. And let's just name the CC. In essence, this is a CC in a class.
I exit out off my conflict, the land mode,
and then I check my villain database by saying, You show Leland brief
and I see that villain 1 50
and has been created on the switch and the name is C C N A.
However real and 1 50
does not have any port assigned to it yet.
So we're gonna take Port 24 right now by default. It belongs to Dylan one,
and we're gonna move it over to Villain 1 50
I'm gonna go to prove mode by saying exit
and I'm gonna show you Port 24.
So you look at a port you say show, then this is interface
F zero slash 24. So interfaces show interfaces
because that's the type of port it is eating. It is 10 megabits per second. Faster Internet is 100 megabits per second.
Then I'm going to say zero.
to the Cisco Port naming convention,
the first number that you see
after the word fast eternity is zero.
This is the slot number.
this means it's asking for the switches. Slot number.
Our switches in this lab on Lee have slot number zero. So you have slot number zero. Look at where I'm highlighting Port one. Slot number two Port A slot number zero Port to slot number zero. Port three Slot number zero Port 24. So the first number
is always the slot number.
If I had another slot on the switch, then I would have
port, one slot number, what one port two and so on and so forth. If I had 1/3 slot or four slot, then you would say f a tree slashed 13 slash 23 slash All the way to 24.
Since we have only one slot and the slot number started zero, all the port names start with zero slash something.
So this 1st 0 is your slot number. Then I say slash And then it's the port I d
for 24 as the idea of 24.
So I'm gonna look at interface fast. Internet zero slash 24
I hit. Enter here is my command.
Or actually let me clean this out a little bit.
So here is my command
right now. Fast. Lieutenant, judo slash 24 is down
and the lion total call is down
now, by default, ports on a switch are usually up.
You don't have to do anything special to bring them up.
However, this port on the other end, if you remember, is connected to a router. Ones f zero slash zero
on a router by default. Ports are actually down. So if the other side of the link is down, our local side is showing down.
you see the Mac address
Right after that, the next line you see something that says empty you 1500 bytes.
MTU stands for maximum transmission unit.
Okay, maximum transmission unit.
This is the maximum packet size, which is the protocol data unit for layer three. And I know we haven't moved to Lear three, but sometimes and see CNN this happens, you have to jump ahead.
So the protocol data unit at Layer three is called the packet. This is the maximum size for a packet that can trance first this port.
So the maximum transmission unit for Internet. Since this is an eternity port is 1500 bytes. That could be a test question.
Once again, the maximum transmission unit for Internet is 1500 bytes.
The band with in kilobits per second
It should actually say k bps. It says
Okay, bit. Okay, that's fine.
The maximum bandwidth for this interface
killer bits a second or 100 megabits a second.
The rest you don't need
actually over here to say is that this port is set to half duplex
by default. Fast Internet pores are in full duplex. But for some reason, this port is set to half duplex. We're gonna go ahead and change that soon.
Next, at the very end of the command, I scroll down by hitting the space bar.
zero collisions and zero late collisions. In an ideal situation, this counter should always remain zero.
If you see that this counter is incremental ng at a rapid pace. You know that you have either a speed
and or a duplex mismatch. So when you have a speed and or a duplex miss match with the other end of the link,
you get an increment in the collusion counter.
So we have gone ahead and look at our looked at our interface fast, Lieutenant Zeros last 24.
Now we're gonna make it an access port.
I go to my global configuration mode
and we have already created villain 1 50 I'm going to scroll up.
You see, we already created villain 1 50 with names. See CNN.
Now I'm gonna apply that villain
to port 24. So the rule of thumb with Cisco is
to make a change to a port, you must first go into the port. And how do I go into port 24? I say interface
fast. Internet zero slash 24 I hit. Enter. I could have also said, Let me exit out of here. I could have also shorten this too. I n t for interface
zero last 24 it would work just to say,
just saves us a bit of typing. So the first command I'm going to do is switch port
now. Switchboard. Mod access
tells this port that you are unconditionally boy going to be an access port. So I hit enter.
And at this point, this port has become unconditionally an access port. Next I'm going to say switch port
1 50 The Second Command.
I have told the port that you are going to be part of villain 1 50 at this point.
So now this port is an access port,
and it carries Villain 1 50 or in this part of villain 1 50 in effect Router one Port F 00 just became part of villain 1 50 because that's the port on the router that's connected to the switch. Port 24 if you look here again.
So since Port 24 on this switch became
part of villain 1 50 the device connected at the other end is router one Port F 00 that also became part of villain 1 50
Now let's look at our show commands.
Let's test this out. Your exit out of here and then exit out again, back to prove mode.
And I'm gonna say show villain
Now, you see, poor 24 is missing from the list of ports
for real and one, and it has been moved down
as proof to us that poor 24 has become part of the land. 1 50 Let's look at the port in a little bit more detail.
fast Internet zero slash 24 then we add the word switch port
and then we hit. Enter.
Now a few things I want to You want to pay attention to in this command?
The name of the port is poor 24. That's easy enough.
The Swiss port on the sweet side. Yes, it is. Enabled
the administrative mode. We just did the commands. Which port? Mode
Because of that, administrative mood stays static
The access more villain that we have created is real. And 1 50 with name. See CNN. Those other fields I want you to look at for now.
Now I'm gonna show you a little shortcut. We are going to go to switch to
now. Switch to port 24 is connected to a router to port F 00 And you're going to see in a minute that switch three. Port 24 is connected to a router. 300 and switch for
So it's three. Poor 24 is connected to a router. Three F 00 and switch four. Poor 24 is connected to route it. 400
So I've kept it pretty consistent in this lab, So
I'm gonna go to switch to
and I'm quickly going to get the housekeeping done.
Okay, That's the housekeeping. Good on I give switch to
the name S W to and I did all the commands that we had covered previously in housekeeping.
I will. I did shortcut versions of the command. Will some of him
I did not set any passwords, because from now on, I'm gonna avoid setting password least we forget, and then we can't log into a device. This time.
I'm not going to create real And 1 50
Once again, I'm gonna put switch to Port 24 in Villain 1 50 But I'm going to skip that step of creating the villain before assigning it to a port.
So the two steps to creating an access port are creative villain,
and then a sign, a villain to the designated port that you need to assign it to. I'm just going to go straight to Port 24
and I'm going to say switch port mod access
that turns it into an access mood port.
And I'm going to say switch for access. Villain 1 50 Now, remember, we haven't created 1,000,000,000 won 50 year. So what happens when I hit Enter? Well, let's see.
It says access villain does not exist creating villain 1 50
So the switch actually does this first step for you. I do not recommend this for the exam.
I, however, do recommend this when you're at work and trying to save time.
Gonna exit out and look at my switch Port
that poor 24 is part of villain 1 50
Now, however, I did not name the villain once we land Ah, see CNN. So it's created a default name called Villain 1 50 So let's go ahead and Nemetz ccn, eh?
We land 1 50 then go into real and 1 50 the name it. See? See any? So now if I check my villain database Do show villain brief.
You see that? My villain name has changed from the default name, which was real and 1 50
again. I'm gonna look at
my switch port in more detail. Sure. Interface
fast. Internet zero slash
Switch port the keyword switch port at the end
and I see that the port is enabled.
Administrative modus static access
access mode. Villain on that port as well. And 1 50 with the name Ccnet.
Now I'm going to go off camera for a minute, and I'm going to finish up
the configuration between
switch three, Port 24 out or three.
And the configuration on switch for poor 24
