1 00:00:00,000 --> 00:00:05,000 Now before we look at the Cisco IOS we need to physically connect 2 00:00:05,000 --> 00:00:07,000 to a Cisco router or Cisco switch. 3 00:00:07,000 --> 00:00:11,000 So how do you connect to a router or a switch? 4 00:00:11,000 --> 00:00:15,000 Well the first thing you’re going to need is a console cable 5 00:00:15,000 --> 00:00:19,000 when you initially configure the device through the console port. 6 00:00:19,000 --> 00:00:26,000 in the old days console cables used to have RJ-45 connectors on both ends 7 00:00:26,000 --> 00:00:32,000 and then you used to have to get a DB-9 connector which would connect 8 00:00:32,000 --> 00:00:36,000 to the serial port of your PC, these days they tends to look like this 9 00:00:36,000 --> 00:00:41,000 so you have an RJ-45 connector on 1 end which you used to connect 10 00:00:41,000 --> 00:00:48,000 to the console of a router or switch and then you have a DB-9 female connector 11 00:00:48,000 --> 00:00:52,000 which you used to connect to the serial port of your PC 12 00:00:52,000 --> 00:00:56,000 now today lots of PC's don’t have serial ports. 13 00:00:56,000 --> 00:01:01,000 So you’ll need to get a USB to serial converter so that you can connect 14 00:01:01,000 --> 00:01:07,000 to the USB port on your PC and then used the DB-9 male connector to connect 15 00:01:07,000 --> 00:01:12,000 to the female DB-9 connector of your console cable 16 00:01:12,000 --> 00:01:17,000 remember a console cable is a rollover cable with pin 1 17 00:01:17,000 --> 00:01:21,000 on 1 side connected to pin 8 on the other side, pin 2 connected to pin 7 18 00:01:21,000 --> 00:01:27,000 3 to 6 and so forth and so on and once again pin 8 to pin 1. 19 00:01:27,000 --> 00:01:32,000 So the pins are rolled from 1 side of the cable to the other side 20 00:01:32,000 --> 00:01:37,000 you then going to have a run some terminal emulation software on your PC or MAC. 21 00:01:37,000 --> 00:01:41,000 There are many examples of terminal emulation software. 22 00:01:41,000 --> 00:01:44,000 HyperTerminal was quite popular in the past 23 00:01:44,000 --> 00:01:48,000 because it came with Windows and it was free but it’s very limited. 24 00:01:48,000 --> 00:01:52,000 Putty is very popular today it’s free and works very well. 25 00:01:52,000 --> 00:01:57,000 One of the issues with Putty is that it only runs on Windows. 26 00:01:57,000 --> 00:02:02,000 Other software that you may be interested in using includes tera term 27 00:02:02,000 --> 00:02:08,000 which is also free and SecureCRT which is very popular with networking engineers. 28 00:02:08,000 --> 00:02:12,000 It runs on both Windows and Mac but it does cause money. 29 00:02:12,000 --> 00:02:17,000 On a Mac you may wanna use SecureCRT or iTerm was an example 30 00:02:17,000 --> 00:02:21,000 I used Royal TSX for a lot of connections on my Mac. 31 00:02:21,000 --> 00:02:25,000 Find software that you prefer using. 32 00:02:25,000 --> 00:02:30,000 Now as in a lot of things in life, there are various options choose what suits you. 33 00:02:30,000 --> 00:02:34,000 Putty is very good if you run Windows and it’s once again free. 34 00:02:34,000 --> 00:02:39,000 If you're running a HyperTerminal you could connect to a router doing the following. 35 00:02:39,000 --> 00:02:42,000 The first thing that you’re going to do is open up a new HyperTerminal session 36 00:02:42,000 --> 00:02:45,000 and then specify the COM port that you going to use 37 00:02:45,000 --> 00:02:49,000 to connect to the Cisco routers or switch and then you need to specify 38 00:02:49,000 --> 00:02:53,000 the speed data bits, parity, stop bits and flow control. 39 00:02:53,000 --> 00:02:56,000 These are typically the values that you’re going to use 40 00:02:56,000 --> 00:02:58,000 when connecting to Cisco router or switch. 41 00:02:58,000 --> 00:03:03,000 Now don’t worry too much about what the value mean 42 00:03:03,000 --> 00:03:05,000 these are typically the values that you’ll configure 43 00:03:05,000 --> 00:03:08,000 when configuring a Cisco router or switch 44 00:03:08,000 --> 00:03:12,000 Just remember that bits per second is 9600 45 00:03:12,000 --> 00:03:17,000 data bits is 8, parity is none, stop bits is 1 and flow control is none. 46 00:03:17,000 --> 00:03:22,000 Now in this video I’m using HyperTerminal, so I'd go to file new connection 47 00:03:22,000 --> 00:03:26,000 I’ve specify my connection let’s say R1 48 00:03:26,000 --> 00:03:31,000 I’ve specify which COM port I’m going to use so as an example COM 3. 49 00:03:31,000 --> 00:03:38,000 I’ll specify that the bits per second is 9600, data bits is 8, parity is none 50 00:03:38,000 --> 00:03:41,000 stop bits is 1 and flow control is none. 51 00:03:41,000 --> 00:03:45,000 Now I can click on OK and I'll hit enter a few times 52 00:03:45,000 --> 00:03:51,000 until I get output on the screen, and as you can see we're connected to a Cisco router. 53 00:03:51,000 --> 00:03:54,000 so just to reiterate what your require 54 00:03:54,000 --> 00:04:01,000 when initially configuring a router or switch you’ll firstly need a console cable 55 00:04:01,000 --> 00:04:06,000 if you've got an older console cable like this, you’ll need to get a DB-9 connector 56 00:04:06,000 --> 00:04:10,000 if you’ve got a newer console cable which looks like this 57 00:04:10,000 --> 00:04:17,000 which has a female DB-9 connector you would connect that to your PC's serial port 58 00:04:17,000 --> 00:04:21,000 or otherwise if you don’t have a serial port on your computer 59 00:04:21,000 --> 00:04:25,000 you’ll need to get a USB to serial port converter 60 00:04:25,000 --> 00:04:29,000 connect the USB cable to the USB port on your PC 61 00:04:29,000 --> 00:04:35,000 and then connect the male DB-9 connector to the female console connector 62 00:04:35,000 --> 00:04:41,000 of the console cable and then you plug the RJ-45 connector into the console 63 00:04:41,000 --> 00:04:44,000 of your router or switch, now as a tip, some routers 64 00:04:44,000 --> 00:04:49,000 have auxiliary ports which were used in the past for modems 65 00:04:49,000 --> 00:04:52,000 don’t connect to the auxiliary port, make sure you connect 66 00:04:52,000 --> 00:04:57,000 to the console port for the initial configuration of your device.
