Now for this demonstration I'm no longer going to use this old Toshiba laptop.

Very few laptops today have built in serial ports.

So I'm going to demonstrate how to connect to a Cisco router and two Cisco switches over there using

this more modern ISIS laptop.

I'm going to show you two ways to connect to the devices.

First method is using this USP to RJ 45 rollover cable.

So I'm going to connect this to one of the ports on this laptop connect that to one of the devices let's

say a switch and then I'm going to show you how to use to USP cables to connect to the router and to

the switch.

So much easier with a USP cable.

So this device is actually going to have three console connections.

Please note once again that this laptop does not have Ethernet ports on it.

You do not connect a console cable to an Ethan at port on a laptop.

This is using a serial or USP connection to the rod or a switch not an Ethan at port.

This laptop only supports Wi-Fi.

It has no Ethernet ports.

I'm not going to use Ethernet on the laptop once again please forgive me for emphasizing this I've just

seen too many people and heard too many horror stories of people blowing their console ports on their

rods and switches because they connect to the Ethan at port on a laptop or P.C. please don't do that

use either a USP or a USB B to console connect to like this OK.

So the first thing I need to do is power up the devices.

So I'm going to plug in the power on the router powered on

switches like these used what's called a kettle lead in the U.K. So a connection like this.

This depend on which country you're in.

So the US will be slightly different but basically I need to just plug in the power of these devices

and as you can see they booting up

okay.

So the next thing I need to do is connect the USP console cable to the P.C. and then I'll connect it

to the console of one of the switches.

So I've got USP to console USP cables are a lot simpler than that.

All I need to do is connect

USP to USP on the device much simpler or again USP

to us be on the road.

So what I've got is USP on the router console cable and one switch USP on the one switch.

And I've got three connections on the laptop now.

I'll plug these out and demonstrate them individually so that you can see how we can work out which

devices which basically what happens is we see that device as a additional device on the laptop.

So I'll do this individually so that you can see how I do it.

One by one.

But that's sort of the idea.

So I've turned on the Cisco router it's making a bit of noise but hopefully it won't disturb the video

too much.

So I am now going to connect the Windows laptops console connection to one of the switches just to show

you the full process I'm remotely controlling that Windows laptop from my Mac.

It just makes it easier with the recordings but I'm physically working on that laptop OK.

So hopefully not too noisy what I'm going to do now is connect the console port to the USP connection

of the laptop so hopefully you can see that clearly I've now connected USP to laptop and the next step

is to connect to the console of the switch.

So hopefully you can see that console connection to the switch used to be on a laptop over there so

use be laptop console switch.

Got my first device connected let's set up the laptop now so that we can actually configure the device

and to do that I'm going to use Patty Patty is what we're going to use to connect to the device OK.

The Cisco ride has quietened down quite a bit now.

Took a while made a bit of noise but once it did it successfully booted up at quieten down.

What I now need to do is download a terminal emulation program so I've physically connected the laptop

to the switch.

But I need a terminal emulation program to connect to the console port in my browser I'm going to simply

look for Patty.

This is free software that you can download.

So the first hit in Google I'm going to go to Download stable release so green and dot org that UK in

my example I want to download the 64 but EMC

I'm not going to download an MSE installer I'm simply going to download a 64 bit XY so generally that's

the software that you want if you're using Windows.

If you're using a Windows computer this is the terminal emulation software that I suggest you use free

software used by millions of people around the world.

If you've got a Mac you've got a built in console or terminal application and the same on Linux but

on windows this is probably the easiest.

So that's now downloaded to simple Excel file that you download and I'm going to double click on that

Windows is complaining but I'm going to install this anyway and run it.

And notice we told that we could use telnet as an example we could use SS H.

But what we want to use is a serial interface so which serial port do we use.

So to find that right click on windows start.

Go to device manager go to Port com and LPT and what you'll see is we've got a USP to serial port here

now.

If you're using a converter like this they generally come with some installation software or you have

to download it.

So really old way of doing it we've got a seedy wrong here.

You'd have to install the driver software on your laptop to get that working.

Follow the instructions that you get with the converter.

I mean the instructions are fairly simple.

It's basically telling us that we need to install the drivers to be able to use this.

So make sure that you have your drivers installed.

Generally you get the drivers if it's a reputable vendor such as this or you can download them.

In my experience the cheap stuff often causes problems.

Fortunately today we have us be connections on the Cisco devices which makes it a lot easier.

So you don't have to mess around with us but notice the computer's com 7.

So in PuTTY I need to set this to com seven leave everything.

I'll set the defaults so 9600 bits per second as an example click open.

And what we should have when I press enter now is a connection to the switch.

And there you go.

I've got a connection to the device.

Now this is known as user mode and I typed enable to go to privilege mode.

The switch already has a configuration on it.

If I log right out you would see something like this.

And we would be asked to press return to get started.

And when I press into or return I see what's called a user mode or user prompt if I use question marks

I just typed question mark there.

I see a list of available commands on the device.

If I press enter it chose me one more available command so I notice more here.

If I press enter here chose one additional command or line of output if I press spacebar I chose a whole

page of output.

Now just to demonstrate this I'm gonna erase the configuration of this device that command E N is enable

that takes me to what's called privilege mode.

This is shorthand for enable and then I typed a few characters and press tab to auto complete the command.

Don't worry too much about this.

I'll show you these commands in more detail in a moment but I wanted to show you what a brand new device

would look like.

So I've basically raised the configuration of that switch and it's now rebooting and I'll show you what

it looks like in a moment.

Once it reboots so what I'll do is while we waiting for that to reboot is let's connect the next device

so for this demonstration I'm going to use a console cable standard USB cable so I'm going to simply

connect it to a port on the P.C..

So something like this simple connection to USB port and I'll connect it to the switch.

So notice now I have USP on the switch USP cable on the P.C. and I've also got a console cable connected

to the switch.

So to connections on the P.C. OK so as you can see now this switch is booting up and it's booting what's

called a burn image.

That's the operating system of the switch.

So while that's waiting once again all right click on windows start and go to device manager and watch

you'll notice is under comports.

We now have to comports This is my USP too surreal connection.

And here's a new USP surreal device.

Com 3.

So what I can do is run Patty again so that I've got two instances of Patty running so I've got my original

Patty running in the background.

That's showing the device booting up and I've got another Patty session.

So basically all I've done now is start Patty twice on this second session the comport that I need to

use is com three so I'm going to specify serial there and change this to com three now actually what's

happened at this point is my P.C. has blue screen.

This is one of the problems when devices boot up.

I've seen this happen so many times on Windows devices.

So notice blue screen here.

So what I would suggest you do is unplug the console cable while it's booting up.

And then once it's booted plug it back in again.

If you have that issue seeing that happen on Windows machines many times.

Okay.

So let's start again.

I'm trying to make this real world and that's a real world issue that you'll often encounter okay.

So going to downloads what I'll do is start Patty again

on the windows start menu go to device manager go to comports notice I've got com 7 and com 3.

Now I must say I've seen them many times with us B to roll over cables.

Happens a lot doesn't happen as often with a USB cable so much better much easier today.

But it is something to be aware of.

If you're using a USP to roll over cable.

Okay so the first one USP to Serial This is a surreal interface and it's com 7.

So press enter and as you can see when the device is booted up fully we see a system configuration dialog

and you can enter what's called the initial configuration dialog.

I strongly suggest that you say no right there.

I will demonstrate the initial configuration dialog so that you can see the full process but for the

real world I suggest you don't do that you simply type No.

And then the mode that you'll end up in is user mode.

So if I press enter multiple times here I see switch with the greater than sign like this.

This is a user mode press question mark once again shows me a list of commands.

Press spacebar shows me a page of commands I can type E N press question mark at this point it shows

me the commands available if I type E Question Mark I've got multiple commands e n question mark only

command available at the moment is enable or press tab that to read types the command and completes

it there and press enter that takes me to what's called privilege mode if I press question mark here

I see a list of additional commands and once again pressing Enter shows me one command at a time pressing

spacebar shows me one page of commands at a time many more commands available in that mode and once

again my laptop has crashed so either there's a problem with the drivers on this USP cable so let's

unplug that so I even need to update the drivers or something else is happening.

So for the moment I'm going to unplug this USP to roll over cable and I'm going to use straight USP

and let's see if that solves the problem

but I want to make this video too long by trying to deal with a buggy driver.

So once again on downloads start patty

or run Patty go to serial but I need to know which comport to use.

So the two composites are 3 and 8.

Now notice it's changed because I'm no longer using a USP to roll over cable I'm using straight USP

here.

So comport has changed so this will be com 8.

Now and there we go we back on that switch.

Notice the switch says console media is USP.

So once again pressing question mark I can see a page of commands at a time when using spacebar.

Many many more commands in privilege mode or enable mode than in user mode.

If I type disable that takes me back to user mode.

Okay but let's get the other device connected so Com 3 in PuTTY I can right click at the top here and

say new session serial and these serial port that I want to use here is Com 3 so this will give me a

connection to my second device.

Notice I typed enable here to go to enable mode.

Now in this device I could use the command show version to see what kind of switch it is.

I'm told that it's a 35 60 C switch.

This is the version of operating system so that's similar to saying Windows 10 or Windows 8 or Windows

7 or whatever.

This is the version of operating system on the device.

The device has been up for 25 minutes at this point.

Press spacebar shows me additional information about this device.

Whole bunch of information here.

You'll learn about this as we go through the course.

But once again show version is a command that shows me the model of switch.

Let's do that on the other switch.

So show version here.

This is a 35 66 switch.

So let's give it a name.

And in Patty if I highlight it's actually copying that information conf confetti or configured terminal

so type SEO and F press question mark shows me that the command available is configure in the press

tab no question mark shows me that I can configure this device multiple ways one of them is terminal.

So in a press t press tab that takes me to what's called Global configuration mode on the switch and

if I use the command host press tab to order complete and right click now it's pasted the name that

I copied previously and noticed the switches name has not changed on the other switch I'll do something

similar.

So show version on the switch.

This is my 35 60 C switch on the press q to quit the output here.

So how do I configure a switch.

What's the command can you remember it.

It's conf T for shorthand or C O N F tab t tab configure terminal and I can use the command host for

shorthand or I can type it out fully if I want to.

That changes the name of the host.

This is what's called Global configuration mode once again that allows me to globally configure the

device.

If I type and it takes me back to what's called privilege or enable mode of press Enter here again and

then I can use the command copy running config startup config to save the configuration.

This is basically saving a configuration from memory to hard drive.

This is a flash drive.

So basically saving it to envy Ram is what it's called non-volatile RAM.

I'm saving the configuration of the device now there is an older command that I find a lot easier.

So on the first switch the thirty five sixty six switch.

If I type and that takes me back to privilege mode and I used a very quick command this let me do that

again W R is an old command that writes the configuration basically saves the config again.

That's an older command and an easier command to use then copy running config startup config for the

exam know this command copy running conflict startup conflict for the real world.

I would know W R OK.

So I've now showing you how to connect to the console of two switches let's connect to the console of

the router.
