So let's start with core 1 show interface gigabit.

1 0 23.

Switch port.

So the command here shows us that this interface is enabled as a switch port administer of mode is dynamic

auto.

In other words it's using DTP but in order rather than desirable operational mode is static access.

In other words it's acting as a access port.

It's currently in VLAN 1.

So interface range and before I do that we can do something similar on other ports such as gigabit 1

0 1.

This port notice it's also an access port.

We can see something similar on gigabit 1 0 2.

It's an access port

1 0 3 is also an access port so let's do it firstly with the ports down to the access switches so gigabit

1 0 1 2 3 switch port mode trunk.

Notice we told that we need to configure the encapsulation first so we firstly need to use the command

switch port trunk encapsulation dot one key and then we specify the mode as trunk so to show run we've

essentially typed these two commands on these three ports get into the habit of specifying the encapsulation

first some switches will require that you specify the encapsulation and that's because some switches

support ISIL and editor at 1 q Packet Tracer in this example only supports dot 1 Q But you still have

to specify the encapsulation so interface range gigabit 1 0 23 to 24 switch port trunk encapsulation

dot 1 key switch port mode trunk

show run they all ports 1 2 and 3 and here ports 23 and 24 the mode is being configured as trunk on

of those ports we need to do something similar on call to notice we're getting spanning tree warnings

about inconsistent ports and that's because core 2 is configured with access ports rather than trunk

ports so interface range gigabit 1 0 1 2 3 these 3 ports down to the access layer switch port trunk

encapsulation dot one key switch port mode trunk

show run that configuration looks good.

So interface range gigabit 1 0 23 to 24 switch port trunk encapsulation not one key switch port mode

trunk

she'll run again.

Go down to the end of our config.

These two commands have been configured on interfaces gigabit 123 and one 0 24.

That looks great.

We are not going to configure the link to the server or the broader as a trunk port.

They will be access ports now on access 1 the two uplink ports gigabit 1 0 twenty three and one zero

24.

Need to be configured as Trump ports so interface range gigabit.

1 0 23 to 24.

Switch port encapsulation or trunk encapsulation dot 1 q switch port mode.

Trunk Show run scroll down.

There's our configuration on those two ports so that looks great.

Now we need to do something similar on Access Switch to interface range gigabit one zero twenty three

to 24 switch port trunk encapsulation not one key switch port mode trunk show run those ports are now

configured as trunk ports lost switch access 3 do something very similar interface a range gigabit 1

0 twenty three to 24 switch port trunk encapsulation dot one key switch port mode trunk

have a look at the config that looks great.

You'll also notice that I'm constantly saving my configuration.

That's a good habit to get into save your configuration often in case you have problems.

So we've configured the trunk ports.

Now we need to configure the access ports.

This port needs to be in VLAN 10.

This port in Vila and 20 this port and V land 30 this port needs to be in VLAN land 100 and this port

will remain in and 1.

So I'll start with access which one show interface gigabit 1 0 1 switch port.

The port is currently in Vila and one needs to be in VLAN 10 so interface gigabit.

1 1 0 1 switch port mode access that is the default switch port access VLAN 10 show run what do we see

that port is in a V land 10 so that looks good now to verify show interface gigabit 1 0 1 switch port

this is the best way to verify notice the port gigabit 1 0 1 as we can see with us show command is in

VLAN 10 so that looks good.

Second access switch interface gigabit 1 0 1 switch port mode access switchboard access VLAN 20.

In this example show run.

Porter's configured correctly in VLAN 20.

The true test however to verify is show interface.

Gigabit 1 0 1.

Switch port.

And what you'll notice here is an access port in VLAN 20 switch 3 interface gigabit.

1 0 1 switch port mode access switch port access VLAN 30 show interface gigabit 1 0 1 switch port this

port as we can see with this show command is in VLAN 30 so that looks great.

Now we need to put to the server in the right VLAN interface gigabit 1 0 20 switch port mode access

switch port access a villain 100 show interface gigabit one zero 20 switch port Port is now an access

port in vlan 100 so this port is correctly configured the last port is on call to interface gigabit

one zero twenty two.

Now before I do anything notice at the moment show run shows us that there is no configuration under

that interface but now switch port mode access switch port access v land 1 What is it going to show

us.

Once we've done that configuration notice it's changed with this option to no negotiate which means

it's disabled DTP so DTP is being disabled on that access port DDP is still running on this port as

an example to show interface gigabit one zero 24 switch port.

Notice the negotiation of trucking is on but if we look at Port Twenty 22 negotiation of trucking is

off so DTP has been disabled on this port because we made it an access port but on the trunk ports DTP

is still enabled now in the real world DTP should be turned off you should turn off dynamic trunk protocol

but in this lab it's okay to use that in the exam make sure that you read the question carefully to

see if you should turn off DTP Okay so I've successfully completed this part of the lab how did you

get on.

Were you able to configure host names passwords VTB villains trunk ports and access ports How did you

get on.

Best way to learn is to practice try it yourself and then watch me do it if needed.

Okay so let's go to the next lab.
