1
00:00:05,070 --> 00:00:08,710
OK so you've just got your new Cisco Rado switch.
2
00:00:08,810 --> 00:00:09,940
You need to configure it.
3
00:00:10,250 --> 00:00:14,520
So how do you configure a brand new Cisco router switch.
4
00:00:14,690 --> 00:00:20,510
Now if it's a remote device and it's been configured correctly you could use a protocol such as telnet
5
00:00:20,900 --> 00:00:28,040
or SSA each secure shell to remotely configure a device like this but generally with Cisco devices you
6
00:00:28,040 --> 00:00:34,450
need to connect to the console port of the Cisco device and configure it locally first.
7
00:00:34,490 --> 00:00:40,310
So how do you connect to a Cisco Radha or Cisco switches console port.
8
00:00:40,310 --> 00:00:42,000
And this video I'm going to show you how to do that.
9
00:00:41,990 --> 00:00:47,990
We're going to look at physical connections using the old traditional methods on an older laptop and
10
00:00:47,990 --> 00:00:51,500
then how to connect to the device using a more modern laptop.
11
00:00:51,500 --> 00:00:57,920
I'm going to show you how to configure the devices from the ground up so how do you connect to a Cisco
12
00:00:57,920 --> 00:00:58,990
Rado switch.
13
00:00:59,000 --> 00:01:00,550
I'm going to show you how to do that right now
14
00:01:05,880 --> 00:01:12,700
Now traditionally a Cisco Rado switch would only have an RJ 45 console port these days fortunately they
15
00:01:12,700 --> 00:01:14,660
now have USB ports.
16
00:01:14,770 --> 00:01:20,050
So I'm going to show you firstly how to connect it to the device using an RJ 45 port and then I'll show
17
00:01:20,050 --> 00:01:26,620
you how to connect it to the device using a USB port so much easier these days using a USB port.
18
00:01:26,620 --> 00:01:33,640
So how do you connect your PC your laptop to the console of a Cisco right or switch in the old days
19
00:01:34,660 --> 00:01:39,000
we used to use what was called a rollover cable like this.
20
00:01:39,250 --> 00:01:47,020
This is known as a roll over cable because pin one on the one side goes to put eight on the other pin
21
00:01:47,020 --> 00:01:53,140
two goes to pin seven point three to pin six all the way to point eight going to pin one.
22
00:01:53,140 --> 00:01:59,880
So all the pins in this cable all rolled one to eight all the way to eight to one.
23
00:02:00,530 --> 00:02:00,780
OK.
24
00:02:00,790 --> 00:02:07,420
So what you would do is connect the one side to the console of the right or switch.
25
00:02:07,420 --> 00:02:10,250
Don't make this mistake.
26
00:02:10,330 --> 00:02:12,570
I've seen many people make this mistake.
27
00:02:12,610 --> 00:02:15,520
Please don't make this mistake.
28
00:02:15,520 --> 00:02:21,730
Don't connect the other side to the Ethan at port on APC.
29
00:02:21,790 --> 00:02:23,380
You'll blow this port.
30
00:02:23,410 --> 00:02:29,740
I've seen it happen too many times where people connect the Ethan at port to their P.C. or laptop and
31
00:02:29,740 --> 00:02:35,650
then connect to the console board of a road or a switch and then it blows the port.
32
00:02:35,650 --> 00:02:39,000
This is what's called an out of band connection.
33
00:02:39,070 --> 00:02:42,620
We are not sending IP across this.
34
00:02:42,640 --> 00:02:46,720
So TCB IP traffic is not going across this cable.
35
00:02:46,720 --> 00:02:54,610
This is a serial port so you would in the old days need a serial port on your laptop to connect to the
36
00:02:54,610 --> 00:02:56,200
router or switch.
37
00:02:56,230 --> 00:03:00,880
So here I've got an old Toshiba laptop really good laptop for its time.
38
00:03:00,880 --> 00:03:09,040
What you would need is what's called a D.B. nine to RJ 45 connector so DP nine converter like this RJ
39
00:03:09,040 --> 00:03:16,180
45 on the one side nine because there's nine pins here female pins and you would connect to the serial
40
00:03:16,180 --> 00:03:18,440
port of your P.C..
41
00:03:18,580 --> 00:03:25,810
So what you would do is connect to the serial port on the one side and to the console port of your rod
42
00:03:25,810 --> 00:03:30,890
or switch on the other side so something like this.
43
00:03:30,890 --> 00:03:36,620
That's how you'd connect your rod or switch to your laptop now rather than doing it that way rather
44
00:03:36,620 --> 00:03:38,830
than having a rollover cable like this.
45
00:03:38,940 --> 00:03:40,360
Nine converter.
46
00:03:40,520 --> 00:03:44,970
What they then did was create a cable like this.
47
00:03:45,200 --> 00:03:50,750
Notice bolting DP nine female connect on the one side RG 45 on the other.
48
00:03:50,750 --> 00:03:57,230
So this would allow me to connect directly to my laptop on the one side so nice connection on the one
49
00:03:57,230 --> 00:04:04,520
side and then connect and then I'd connect to the rod or switch on the other side.
50
00:04:04,580 --> 00:04:12,050
So RJ 45 on the one side that would go to the console port of the roto switch DP nine female connector
51
00:04:12,230 --> 00:04:13,660
on the other side.
52
00:04:13,850 --> 00:04:22,370
It's much easier to have a single roll over cable like this DP nine to RJ 45 than it was to have to
53
00:04:22,400 --> 00:04:28,970
RJ 45 and then have to get a DP nine to RJ 45 converter or connector like this.
54
00:04:29,000 --> 00:04:33,190
So that's the old way of doing things.
55
00:04:33,200 --> 00:04:40,520
The problem is today's laptops don't have serial interfaces like this.
56
00:04:40,520 --> 00:04:44,480
So how do you connect a modern laptop to a rod or switch.
57
00:04:44,840 --> 00:04:54,120
If you don't have a serial interface here's a more modern laptop ISIS laptop one running Windows 10.
58
00:04:54,400 --> 00:05:02,530
It doesn't have serial interfaces so I can't connect this serial cable to this laptop.
59
00:05:03,070 --> 00:05:10,750
So what we had to do and things have got easier today put what we had to do in those days is use us
60
00:05:10,750 --> 00:05:13,420
B to serial converter.
61
00:05:13,480 --> 00:05:20,920
So what I'd have to do is buy something like this so here's an example.
62
00:05:21,040 --> 00:05:22,300
You have to be careful with some of these.
63
00:05:22,300 --> 00:05:23,470
Some of them don't work.
64
00:05:23,500 --> 00:05:26,250
They were dodgy chips inside of them.
65
00:05:26,380 --> 00:05:31,420
A lot of cases they wouldn't work but you'd get something reputable like this.
66
00:05:31,510 --> 00:05:40,440
This would give you a male DB nine connector so you could connect the female console cable to this and
67
00:05:40,440 --> 00:05:42,040
then this would go into your laptop.
68
00:05:42,300 --> 00:05:47,750
So USP poured like that and then some of these cables out of the way.
69
00:05:48,420 --> 00:05:53,120
And then you would have your console connection to the right or switch.
70
00:05:53,310 --> 00:06:00,690
So something like this console on the right or a switch and then you would have us be on the laptop.
71
00:06:01,290 --> 00:06:05,280
So that has been the way to do it for quite a few years.
72
00:06:05,940 --> 00:06:13,050
But Cisco have started adding U.S. B connections to the writers of switches.
73
00:06:13,230 --> 00:06:14,100
So here.
74
00:06:14,100 --> 00:06:15,780
Notice this switch.
75
00:06:15,780 --> 00:06:21,410
More modern switch has a U.S. B connector so much much better so much easier.
76
00:06:23,640 --> 00:06:30,570
So what you would do is get a USB cable not micro USP standard USP and you would connect to a USB port
77
00:06:30,570 --> 00:06:31,740
on your laptop.
78
00:06:31,740 --> 00:06:35,060
That's a much easier way of doing it.
79
00:06:35,160 --> 00:06:36,590
So there is a bit of history.
80
00:06:36,690 --> 00:06:45,800
So the first part of the puzzle is you need to physically connect your laptop to a road or switch.
81
00:06:45,810 --> 00:06:46,970
There are two ways to do it.
82
00:06:46,980 --> 00:06:52,860
You can either use a traditional object 45 connector or you can use a USP connector.
83
00:06:52,860 --> 00:06:55,020
In this video have now shown you both ways.
