All language subtitles for 2. Packet Tracer Campus Network Answers Part 1 Power on and hostname configuratio

No he told that to one of the first things we need to do is configure whose names.

But notice the problem in the topology when I click on a switch and go to see lie.

We're told that the device needs to be powered on so one of the first things we need to do is add a

power supply module to the switch in this example.

I'll add two because this is a core switch and as you can see there the switch is now booting up and

we see a system configuration dialog asking us whether we want to enter the initial configuration dialog

we're going to say no for these labs and we're going to manually configure the switch so the switch

has a base config.

This is a base config that will be applied when you raise the configuration of a switch so switch one

has booted up.

Let's do something similar to the other switches so in the second course switch I'll add power to the

switch.

And as you can see it's booting up

do something similar with the access switches.

In this example because the access switches I'll only add a single power supply switch as booting up.

He has the second Access Switch

such as booting up as well and he has the lost switch single power supply switch is bidding up on the

router

if we try and go to see a lie We're told that the device must be powered on.

So what we need to do is turn the rudder on now unlike the switches we don't have to insert power supplies.

We simply need to turn the radio on most Cisco brought us have an on off switch lower end Cisco switches.

Don't you simply plug in the power to turn them on now that the switches of booted we can configure

host names.

So this is cool one.

Give it a name of call 1

core to hostname court T.

You can see the prompts changed to show that it's cool too.

It's a very good idea to configure host names and other basics on your switches.

Now what a lot of network engineers will do is they will have this in notepad so that they can simply

copy and paste a bunch of configuration into multiple devices.

What we'll do here is do it manually so that you can learn all the commands so that's access one configured.

There's access to configured he has access 3 so hostname access 3

so whose names for the switches are configured.

What about the router.

I'm going to call this Internet router you could call it really anything you want to in the exam.

Just follow the instructions if they tell you to configure it with a specific name then do that.

The next thing we need to do is shut down unused interfaces.

So in this topology switch one has interfaces gigabit 1 0 1 2 3 20 23 and 24 in use.

Show IP interface brief will show us the status of interfaces so scrolling up we can see that various

interfaces are up up 1 2 and 3 which is correct per our topology 20 is up

23 and 24 are also up we can already see a problem however this code switch has a bunch of interfaces

marked in orange that means that spanning tree is blocking those ports.

So we'll need to fix that later.

But as you can see here interface 2 3 and 24 are blocking on that core switch.

We going to want to optimize that and fix it but for now let's manually shut down unused interfaces.

It's important to do that from a security point of view.

So interface gigabit.

1 0 4 2 19 needs to be shut down.

So what are we going to do here is actually use the range command to interface a range 4 to 19 and shut

those interfaces down

so we've essentially shut down this interface of this interface.

This interface and others in the range 4 to 19 so scrolling up notice port 19 has been shut down 20

hasn't been shut down.

It needs to stay up 21 and 22 need to be shut down however so show IP interface brief

these two need to be administratively shut down.

Its interface range gigabit one zero twenty one to twenty two.

Shut that down.

Show IP interface brief.

We need to do something similar on these interfaces so interface gig 1 0 1 1 2 4 and I should use a

range there.

Shut those ports down to show IP interface brief now shows us that all unused ports are administratively

shut down I'll save the configuration at this point.

Get in the habit of saving your config on a regular basis.

So on the switch we need to do something similar.

Show IP interface brief there are multiple interfaces on the switch that need to be shut down.

This command shows us that these three interfaces are up.

That's correct 23 and 24 need to stay up as well as 22.

This interface is showing down because we'd need to know shut the interface on the broader.
