00:00:00,480 --> 00:00:05,730
However before looking at the Cisco IOS you need to connect to a device.

2
00:00:06,000 --> 00:00:08,790
And in this video I'm going to connect to a Cisco router.

3
00:00:09,120 --> 00:00:14,790
So I want to show you the physical connections so that you know how to connect to the console of a Router

4
00:00:15,140 --> 00:00:21,680
Set up your computer to access the console using hyper terminal as an example in Windows.

5
00:00:21,690 --> 00:00:29,430
There are many terminal emulation options available to you hyper terminal Tehrik term and Patty are

6
00:00:29,430 --> 00:00:35,460
some examples who turn on the router and look at the start up process to see how the Rodda boots.

7
00:00:35,550 --> 00:00:41,820
And then we'll run the initial configuration dialog which isn't really used that often by networking

8
00:00:41,820 --> 00:00:48,050
engineers in the real world but it's well worth looking at it so that you're aware that it exists.

9
00:00:48,120 --> 00:00:54,270
The initial configuration dialog allows you to configure some basic configuration options on a Cisco

10
00:00:54,270 --> 00:01:00,280
router but these days Cisco have introduced other ways of configuring devices.

11
00:01:00,390 --> 00:01:07,500
So most Cisco engineers only look at the initial configuration dialog once or twice and I suggest you

12
00:01:07,500 --> 00:01:08,770
do the same.

13
00:01:08,790 --> 00:01:10,830
Have a look at it see what it does.

14
00:01:10,890 --> 00:01:13,260
Get an understanding of what it provides.

15
00:01:13,380 --> 00:01:19,500
But in the real world you're going to configure networking devices using the command line interface

16
00:01:19,920 --> 00:01:26,020
and specific commands rather than following the initial configuration dialog.

17
00:01:26,040 --> 00:01:33,220
So as mentioned the exec interface is where you going to be configuring networking devices and this

18
00:01:33,220 --> 00:01:37,880
is WAY YOU as a Cisco engineer are going to be spending a lot of time.

19
00:01:38,160 --> 00:01:46,180
You need to get very very comfortable with the layout and commands available in the exec interface.

20
00:01:46,230 --> 00:01:52,200
You'll probably never memorize all the commands available in the Cisco IOS.

21
00:01:52,200 --> 00:01:58,890
There are thousands and thousands of commands that you need to learn at least some of them to be able

22
00:01:58,890 --> 00:02:02,110
to configure a Cisco router or switch.

23
00:02:02,340 --> 00:02:04,610
So we're going to look at some of the modes available.

24
00:02:04,680 --> 00:02:11,940
And as mentioned this causes a lot of confusion don't type the right C'mon in the wrong mode as the

25
00:02:11,940 --> 00:02:14,300
Cisco Radu a switch or won't accept it.

26
00:02:14,640 --> 00:02:18,420
So if a command is not accepted by your router will switch.

27
00:02:18,420 --> 00:02:24,720
Firstly make sure that you're in the right mode and secondly make sure that you are working on the right

28
00:02:24,720 --> 00:02:26,190
device.

29
00:02:26,190 --> 00:02:31,890
Now like all things in life the more you practice the easier it becomes.

30
00:02:31,890 --> 00:02:36,480
So spend time practicing commands on Cisco routers and switches.

31
00:02:36,540 --> 00:02:42,780
I'm going to show you some exec interface tips and tricks which you'll find really useful in the real

32
00:02:42,780 --> 00:02:44,770
world to save you time.
