So let's have a look at the road.

Now don't forget to that a rider needs to be turned on.

You need to switch it on and then it will boot up and you'll have access to the console.

So again this interface is showing down on the switch because we need to enable the interface on the

rider so the rider has booted up show IP interface brief.

I'm gonna go on to give it a 0 0 on this case gigabit 0 slash 0 slash 0 and no shut the interface and

then I'll do the same on interface gigabit 0 slash 0 slash 0 0 no shut the interface interfaces come

up now a router when it boots up for the first time we'll have a name of Roorda this rider has a name

of Internet rider so that was previously configured.

Notice the interfaces are now green.

So when I go back to the switch we can see that the interface came up so show IP interface brief we

can see that these interfaces are up.

Other interfaces are down reveal and one is administratively down.

Now if you don't want to spend time doing this then don't.

But in the real world it's best practice that you shut it down.

Interfaces that are not in use.

So we're going to shut down interface gigabit 1 0 for up to 1 0 21 so to 21 will be shut down.

So do show IP interface brief will show us our interfaces.

There's the show command these three interfaces are up other interfaces are now down interfaces gigabit

once there are 22 23 and 24 are up.

That's great.

These interfaces are down so interface gigabit one slash one slash one to four and I should use a range

again.

Shutter those interfaces down to show IP interface brief we have administrative shut down all the physical

interfaces on the switch so let's configure the access switches.

He has access 1 show IP interface brief various interfaces are down the interfaces that need to be up

0 3 and 23 and 24.

Now it's especially true on a access switch that you shut down unused interfaces.

Otherwise someone could simply plug themselves in to a wall socket and get access to your network.

In other words they could plug the computer into any network port that's open we need to shut down gigabit

1 0 4 to 22

so if we have a look at that switch again show IP interface brief all the unused ports are shut down

remaining ports are gigabit one slash one slash one two four shut them down.

Now you may want to write a script to do this to save you time especially when you've got two switches

that are using the same ports in the same way as with switch one only port won and port 23 and 24 up.

No no just something interesting on this switch port gigabit 1 0 3 is up was in the diagram it's gigabit

1 0 1

so that's probably an issue in the package trace and network saw fixed to that

we can see that interface gigabit one slash three is now down but that means that we need to enable

those port and disable this port in the topology that I've made available I'll fix that mistake so that

you don't have to encounter this problem.

Show IP interface brief in the real world diagrams may be incorrect Okay so that looks good.

We can do something similar on access to so an access to interface range gigabit.

1 0 2 2 22.

That should be shut down.

So again show IP interface brief gigabit 1 0 1 is up.

The interfaces are down 23 and 24 hour up.

That's a good interface of range gigabit one slash one slash one to four all shut those ports down.

So show IP interface brief those ports are also shut and I'll save the configuration loss which to do

is switch 3 show IP interface brief gigabit 1 0 1 is up 23 and 24 up

why are we doing this.

It's for security reasons you don't in a lab have to do this but it's best practice

so in other words it's good practice to do this in the real world

in a lab you may decide that it's not necessary for the exam do what they say.

So in the CCMA exam follow the instructions that you've given.

Don't improvise do what they say.

So that interfaces up the interfaces are up.

I'm going to save the configuration so we've now successfully shut down unused interfaces.

The next step is to configure enable and v2 won't passwords of Cisco.
