1 00:00:04,880 --> 00:00:09,330 Okay, so I could use this console cable so let's try that once again. 2 00:00:09,330 --> 00:00:11,460 Hopefully it won't blue screen. 3 00:00:11,460 --> 00:00:18,240 So on the PC, I'm going to connect the USB console cable and then I'll connect this to the console 4 00:00:18,930 --> 00:00:20,700 of the router. 5 00:00:21,180 --> 00:00:26,710 So basically connected to the console of the router and to the USB of the PC. 6 00:00:29,390 --> 00:00:29,750 Okay. 7 00:00:29,760 --> 00:00:31,290 So once again right click on windows start. 8 00:00:31,290 --> 00:00:37,110 Go to Device Manager, I've got a additional comport. 9 00:00:37,120 --> 00:00:42,690 Now, it's not showing up as com 4 the whole process once again is to start PuTTY 10 00:00:47,050 --> 00:00:58,720 select serial, serial port that I'm going to use is com 4, click open and what I've got now is a connection 11 00:00:58,930 --> 00:01:08,830 to a router, if I type show version this shows me that the router is running Cisco IOS XE software version 12 00:01:08,830 --> 00:01:18,050 16 0 3 0 3 pressing spacebar, I see a whole bunch of additional information and I can see that this is 13 00:01:18,050 --> 00:01:27,410 a Cisco ISR 4321 B K9 router so that is an example of a Cisco router, I can type enable once again 14 00:01:28,010 --> 00:01:35,180 I can type CONF T to go to global configuration mode, type END to go to privilege mode, type disable 15 00:01:35,180 --> 00:01:43,730 to go back to user mode, so user mode type enable to go to enable or privilege mode type CONF T to 16 00:01:43,730 --> 00:01:49,610 go to global configuration mode you have to configure the device in configuration mode or global configuration 17 00:01:49,610 --> 00:01:57,830 mode and they are sub-modes after that, I'll show you those later and then END takes me back to enable 18 00:01:57,830 --> 00:02:04,460 mode, disable takes me to user mode and then I can type exit to exit out of the router I am connected 19 00:02:04,520 --> 00:02:10,030 to console 0 of the router, but now let's get you to do this. 20 00:02:10,100 --> 00:02:16,460 So what I'm gonna do is start Packet Tracer please make sure that you've downloaded packet tracer 21 00:02:16,970 --> 00:02:22,280 and that you've got access to Packet Tracer because I'm gonna show you how to do something very similar 22 00:02:22,340 --> 00:02:23,820 using Packet Tracer. 23 00:02:24,140 --> 00:02:30,500 So when Packet Tracer boots up I've got to log in, I've shown you in separate videos how to do this 24 00:02:37,900 --> 00:02:48,640 okay so the physical router that I'm using is a Cisco, type enable here show version allows me to see 25 00:02:48,640 --> 00:02:55,990 what type of router it is it's a Cisco ISR router, once again show the for short we'll show version 26 00:02:56,230 --> 00:02:57,430 full command. 27 00:02:57,760 --> 00:03:06,530 This allows me to see what type of router, I'm using it's an ISR 4321, in Packet Tracer there have 28 00:03:06,990 --> 00:03:15,590 ISR 4321, routers so if I click on the router you'll notice that this looks very similar to the physical 29 00:03:15,590 --> 00:03:23,460 router that I have right here and if I click on CLI you'll notice that once this boots up that it's very 30 00:03:23,460 --> 00:03:30,090 similar to the router that I'm using now when a device boots up once again and it doesn't have a safe 31 00:03:30,090 --> 00:03:37,500 configuration we'll see this initial configuration dialog, I'm gonna type NO to bypass that and on this right if 32 00:03:37,500 --> 00:03:48,060 I type show version and press spacebar you'll notice this looks very similar to my physical router, so 33 00:03:48,060 --> 00:03:53,830 here's the physical router and here's the packet tracer router. 34 00:03:54,030 --> 00:04:01,590 Notice how that looks very similar to this slight difference in output but very very similar. 35 00:04:01,620 --> 00:04:04,350 Now we'll talk about configuration registers late in the course. 36 00:04:04,350 --> 00:04:07,220 This has actually been changed to 2 1 4 2. 37 00:04:07,230 --> 00:04:10,290 The default is 2 1 0 2. 38 00:04:10,290 --> 00:04:11,810 But again we'll talk about that later. 39 00:04:11,810 --> 00:04:17,959 So don't worry about it now we can see licensing information on the packet tracer router a similar kind 40 00:04:17,959 --> 00:04:26,400 of information on a physical router. I specifically once again bought this rather because it's available 41 00:04:26,400 --> 00:04:28,040 in Packet Tracer. 42 00:04:28,050 --> 00:04:33,480 Now you don't just click on a router in the real world to connect a console connection to the router, what 43 00:04:33,480 --> 00:04:36,920 you actually need to do is have a console cable. 44 00:04:36,930 --> 00:04:42,900 So what I'm gonna do is add a PC to my packet tracer topology and then I'm gonna go to connections 45 00:04:43,080 --> 00:04:46,410 and notice this blue cable is a console cable. 46 00:04:46,680 --> 00:04:54,870 I'm gonna connect the RS-232 interface to the console of the router. 47 00:04:55,080 --> 00:05:00,600 Now routers have what are called the auxiliary ports and console ports auxiliary ports in the old days 48 00:05:00,600 --> 00:05:06,150 we used to connect modems to a router so you could phone the router to use an outer band connection to 49 00:05:06,270 --> 00:05:15,010 configure it, not use that much these days but notice now on this PC, if I click on the PC and go 50 00:05:15,010 --> 00:05:21,320 to desktop and I'll just make this bigger I can select terminal. 51 00:05:21,360 --> 00:05:27,210 This is what's called the well-known defaults for a console port on PuTTY as an example. 52 00:05:27,210 --> 00:05:37,380 If I right-click and go change settings, connection, serial you'll notice these values are the same as 53 00:05:38,550 --> 00:05:42,900 these values in Packet Tracer. 54 00:05:42,900 --> 00:05:45,030 So this is the physical router. 55 00:05:45,090 --> 00:05:47,100 This is Packet Tracer. 56 00:05:47,100 --> 00:05:50,420 Now there is one difference you'll notice flow controllers X on, X off. 57 00:05:50,670 --> 00:05:52,630 Generally that should be set to None. 58 00:05:52,740 --> 00:05:55,290 And that might be what's causing the problem. 59 00:05:55,290 --> 00:05:58,290 So these are the values that you generally want to use. 60 00:05:58,340 --> 00:06:00,080 So I'll click Okay. 61 00:06:00,180 --> 00:06:06,540 So what you'll notice now is I've connected to the router using packet tracer and that looks very similar 62 00:06:06,990 --> 00:06:08,810 to PuTTY. 63 00:06:08,820 --> 00:06:11,850 So this is PuTTY, show version. 64 00:06:11,850 --> 00:06:18,260 But once again that's crashed so flow control didn't help, so my laptop crashed once again looks like 65 00:06:18,260 --> 00:06:25,790 that USB connection isn't very good but what I wanted to show you is once again this is Packet 66 00:06:25,790 --> 00:06:26,660 Tracer. 67 00:06:26,660 --> 00:06:37,940 Show version, looks very similar to a physical router if I open up device manager once again and look 68 00:06:38,030 --> 00:06:47,780 at my console ports here my various console ports so com 4 if I remember right is the router open 69 00:06:47,780 --> 00:06:57,420 that up again run PuTTY again go to console 4 here is my router so show version on the router. 70 00:06:57,910 --> 00:07:06,610 You'll notice it looks very similar to Packet Tracer, PuTTY and Packet Tracer looks very much the same. 71 00:07:06,640 --> 00:07:10,450 So the great thing about packet tracer and what I'll do, is I'll just turn off this physical router right now 72 00:07:10,450 --> 00:07:16,510 so that the room becomes quieter and that we don't have it crashing my windows laptop again. 73 00:07:16,600 --> 00:07:24,110 The great thing about Packet Tracer is you can test this stuff as if you're connected to real devices. 74 00:07:24,250 --> 00:07:27,590 So let's add a switch that you can see the switches, 75 00:07:27,770 --> 00:07:32,650 here's a 3650 switch again in PuTTY. 76 00:07:32,650 --> 00:07:42,530 I'll open up a new session and I'll connect to let's say com 3, so com 3. 77 00:07:42,650 --> 00:07:53,940 One of my USB connections, this is a 3560 C switch show version that went a bit quick but notice 78 00:07:53,940 --> 00:07:59,930 at the bottom here 3560 in Packet Tracer. 79 00:08:00,130 --> 00:08:02,360 He has a 3560. 80 00:08:02,600 --> 00:08:11,360 So what I could do as an example is add another PC to my topology and then go to connections select 81 00:08:11,360 --> 00:08:21,290 console cable and connect to RS-32 cable to the console port of the switch on the PC go to 82 00:08:21,290 --> 00:08:29,570 desktop go to terminal select the defaults and what you'll notice is we see a switch booting up and 83 00:08:29,570 --> 00:08:34,850 you can see the full process, I'll go right to the beginning can see here the switch is starting up and 84 00:08:35,210 --> 00:08:42,860 that looks very similar to real physical switch booting up and then we get the initial configuration 85 00:08:42,860 --> 00:08:51,860 dialog I'll say no to bypass that and notice I'm on this packet trace switch which is a 35 60 24 port 86 00:08:51,950 --> 00:09:00,020 switch going to my physical switch, this is a slightly different switch and what I want you to see and 87 00:09:00,040 --> 00:09:08,860 I'll put these side by side, is packet tracer is very, very similar to a real switch. 88 00:09:09,400 --> 00:09:17,950 So on a real switch, I'll type exit, we get console port is available, packet trace a top exit we get console 89 00:09:17,950 --> 00:09:26,470 is now available press enter in packet tracer, press enter on the real switch type enable, type enable type 90 00:09:26,470 --> 00:09:32,630 CONF T, type CONF T, type End here, type end here. 91 00:09:33,090 --> 00:09:41,340 Press question mark on this side, press question mark you'll notice that it looks very much like a real 92 00:09:41,340 --> 00:09:44,460 switch real switch gives you the the real thing. 93 00:09:44,460 --> 00:09:49,020 It's the best way to do things but not everyone can afford to buy a bunch of switches so packet tracers 94 00:09:49,050 --> 00:09:55,230 all you need, you can connect to the consoles of multiple devices by adding PCs to your topology but 95 00:09:55,230 --> 00:10:00,390 you don't have to do that on a switch like this you could just go to the CLI now it has to be powered 96 00:10:00,390 --> 00:10:07,530 on so I have to add a power module to this specific switch but if I click on CLI now, I can see the seal 97 00:10:07,530 --> 00:10:12,570 of the switch without having to actually connect a console cable to the switch so packet tracer gives 98 00:10:12,570 --> 00:10:19,770 you two options you can either do it this way or you can simply click on the switch go to CLI and see 99 00:10:19,770 --> 00:10:27,180 the CLI directly without using a console cable but this replicates or simulates what happens in the 100 00:10:27,180 --> 00:10:32,490 real world, in the real world you can't just click on a device to access the console you have to physically 101 00:10:32,520 --> 00:10:36,840 connect to it either via the console or remotely using Telnet or SSH. 102 00:10:37,380 --> 00:10:43,320 Okay that was a long video but hopefully, I've now shown you how to connect to the console of routers 103 00:10:43,320 --> 00:10:50,200 and switches using multiple options. I've shown you how to use the old way of doing it roll over cable. 104 00:10:50,280 --> 00:10:54,060 I've shown you how to use USB to roll over cable. 105 00:10:54,090 --> 00:11:00,450 I've shown you USB cables directly to switches, USB, obviously much easier and much better today. 106 00:11:00,570 --> 00:11:05,460 And that's the preferred way to do it but if you come across an old router or switch you may need to use 107 00:11:05,460 --> 00:11:10,060 one of these not as good as USB but there you go. 108 00:11:10,080 --> 00:11:16,590 Okay, but make sure that you can get this working make sure that you can connect your PC in packet 109 00:11:16,590 --> 00:11:21,170 tracer to the console of the router and switch and gain access to the device.
