1 00:00:05,140 --> 00:00:07,770 In this video, I'm going to show you some Packet Tracer tips and tricks. 2 00:00:07,810 --> 00:00:12,120 Please make sure that you go through this video so that you'll learn these tips and tricks 3 00:00:12,130 --> 00:00:18,190 they will be especially beneficial when you use simulation mode in Packet Tracer. 4 00:00:18,190 --> 00:00:21,100 Now I'm not going to cover everything Cisco have this course. 5 00:00:21,100 --> 00:00:26,910 Introduction to Packet Tracer so if you really want to learn how to use Packet Tracer then this is a 6 00:00:26,910 --> 00:00:28,740 great course to take. 7 00:00:28,740 --> 00:00:30,650 It's a free course once again. 8 00:00:30,660 --> 00:00:35,510 Well worth your time taking this course if you want to learn the ins and outs of Packet Tracer. 9 00:00:35,700 --> 00:00:40,800 In my course, I'm not trying to teach you how to use all the features of Packet Tracer. We're just 10 00:00:40,800 --> 00:00:45,070 going to use some of the features that help us get started and help us better. 11 00:00:45,090 --> 00:00:47,450 build networks in Packet Tracer. 12 00:00:47,820 --> 00:00:53,400 So you can launch this course on Cisco's website and go through the course it once again covers a lot 13 00:00:53,400 --> 00:01:00,010 of features available in Packet Tracer. So there's an introduction to packet tracer. 14 00:01:00,190 --> 00:01:04,640 You can learn about the user interface and how to use simulation mode. 15 00:01:04,690 --> 00:01:09,280 We're going to use simulation mode as part of this course and I want to show you two important tricks 16 00:01:09,640 --> 00:01:11,700 before you use simulation mode. 17 00:01:11,890 --> 00:01:15,710 But if you want to learn more about simulation mode once again have a look at this course. 18 00:01:15,820 --> 00:01:21,880 You can also learn about the physical view in Packet Tracer as well as assessments which we going to 19 00:01:21,880 --> 00:01:23,380 use in this course. 20 00:01:23,380 --> 00:01:31,030 You can learn about IoT controlling smart devices and various other options in Packet Tracer such as 21 00:01:31,360 --> 00:01:36,190 creating and programming objects whole bunch of options are available in Packet Tracer. 22 00:01:36,340 --> 00:01:41,380 We are only using a small subset of the features and Packet Tracer because that's all we need to build networks 23 00:01:41,410 --> 00:01:42,840 using Packet Tracer. 24 00:01:42,880 --> 00:01:48,550 We are concentrating on the configuration of the devices within packet trace of rather than learning about 25 00:01:48,580 --> 00:01:50,540 all the features in Packet Tracer. 26 00:01:50,950 --> 00:01:59,350 But that being said very important, please go to options, preferences when you start a packet tracer. 27 00:01:59,350 --> 00:02:02,240 And notice this tab miscellaneous. 28 00:02:02,410 --> 00:02:10,449 Please check this checkbox buffer filtered events only that will save you from having problems where 29 00:02:10,449 --> 00:02:14,380 the packet tracer buffers are overrun when you use simulation mode. 30 00:02:14,380 --> 00:02:16,390 If you don't know what that is don't worry. 31 00:02:16,510 --> 00:02:21,460 Take my advice and check this option. Under interface 32 00:02:21,460 --> 00:02:27,250 there are various options where you can show device model labels, show device name labels, you can show 33 00:02:27,250 --> 00:02:33,850 port labels in the logical workspace something that I find very useful is under font and make the fonts 34 00:02:33,910 --> 00:02:36,190 a lot bigger for the CLI. 35 00:02:36,760 --> 00:02:39,820 So I'll set this to 16 as an example. 36 00:02:39,970 --> 00:02:41,830 You can change the font used. 37 00:02:41,860 --> 00:02:46,450 You can change the size of the menus if you prefer. 38 00:02:46,450 --> 00:02:51,940 But for me, the most important option is changing the CLI. I'm going to click apply and then I'm going to 39 00:02:51,940 --> 00:02:57,910 close this down. Now we'll create a lot of networks together. 40 00:02:57,910 --> 00:03:06,860 But I just want to show you that we have routers, switches, hubs, wireless devices and firewalls as some 41 00:03:06,860 --> 00:03:13,160 of the network devices available in Packet Tracer. Packet Tracer very versatile fantastic software free 42 00:03:13,160 --> 00:03:14,600 once again from Cisco. 43 00:03:14,600 --> 00:03:20,630 It does have some limitations but it allows you to build a lot of networks. Under end devices we have 44 00:03:20,630 --> 00:03:23,090 laptops and PCs as an example. 45 00:03:23,090 --> 00:03:29,610 So I could add a laptop to my topology and add a PC to my topology. 46 00:03:29,840 --> 00:03:38,910 I could go back to network devices and I could select a switch as an example and I could add a 3650 47 00:03:38,910 --> 00:03:40,640 switch to the topology. 48 00:03:40,710 --> 00:03:46,200 Now I'll be discussing network devices what routers are, what switches or what hubs are in a lot of detail 49 00:03:46,230 --> 00:03:47,280 in the upcoming video. 50 00:03:47,280 --> 00:03:49,430 So don't worry too much about this. 51 00:03:49,470 --> 00:03:55,800 I'll also be discussing cabling types. So clicking on connections I could grab what's called a straight 52 00:03:55,800 --> 00:04:02,910 through copper cable and I could connect the Fast Ethernet cable on my PC to a gigabit interface 53 00:04:02,940 --> 00:04:09,250 on my switch. Again don't worry too much about this if you don't know much about networking. 54 00:04:09,330 --> 00:04:13,380 We'll be discussing a lot of these options in the upcoming videos. 55 00:04:13,410 --> 00:04:20,339 I'll grab another cable select another interface on the switch say gigabit 1/0/2 connect 56 00:04:20,399 --> 00:04:23,550 that to the PC and Fast Ethernet0 and 57 00:04:27,030 --> 00:04:35,110 what I'll do on the specific switch, I'll click on it and I'll drag a power supply into the switch. 58 00:04:35,180 --> 00:04:39,140 This switch requires that you add a power supply to start it up. 59 00:04:39,140 --> 00:04:44,810 And if I click on CLI I'll be able to see the switch boot up. Again I'll cover a lot of these details 60 00:04:44,810 --> 00:04:45,910 later. 61 00:04:45,980 --> 00:04:49,820 What I want to point out however is that we have real-time mode. 62 00:04:49,820 --> 00:04:56,000 This is stuff happening in real time and then we have simulation mode which allows us to see what's 63 00:04:56,000 --> 00:04:57,380 happening behind the scenes. 64 00:04:57,380 --> 00:05:02,460 We can actually see the traffic sent on the network when we use simulation mode. 65 00:05:02,540 --> 00:05:09,200 So I'm gonna go back to real-time and I'm going to click on this PC and I'm going to go to config 66 00:05:09,470 --> 00:05:11,540 FastEthernet0 67 00:05:11,600 --> 00:05:14,830 Now again I'm gonna explain Ethernet interfaces. 68 00:05:14,840 --> 00:05:15,860 I'm going to explain 69 00:05:15,860 --> 00:05:16,610 IP addresses. 70 00:05:16,610 --> 00:05:22,070 I'm gonna explain cabling in the upcoming video so don't worry too much about this for the moment. 71 00:05:22,070 --> 00:05:30,550 What I'm going to do is configure an IP address on this PC and give it a subnet mask as follows. 72 00:05:30,550 --> 00:05:32,160 Again don't worry too much about this. 73 00:05:32,170 --> 00:05:39,220 I just need to configure an IP address to show you one of the options in Packet Tracer. 74 00:05:39,220 --> 00:05:46,040 If I go back to desktop command prompt this gives me a prompt similar to what you'll have in windows 75 00:05:46,220 --> 00:05:52,220 and if I Ping an IP address like this the PC will send traffic into the network but I don't actually 76 00:05:52,220 --> 00:05:55,280 see anything except the results. 77 00:05:55,910 --> 00:06:02,630 If I configure this laptop with an IP address and again don't worry too much about what I'm doing here 78 00:06:03,590 --> 00:06:07,850 I'm going to explain all of these options in a lot of detail in a moment. 79 00:06:07,940 --> 00:06:15,840 So I've given this laptop an IP address that ends in 2 when I go back to the desktop and ping that 80 00:06:15,870 --> 00:06:17,180 IP address again. 81 00:06:17,280 --> 00:06:24,980 I get a reply from the laptop ping basically just sends a message into the network saying Are you there? 82 00:06:25,910 --> 00:06:31,550 In the first case because I hadn't configured the laptop with an IP address the request timed out. 83 00:06:31,550 --> 00:06:38,810 In other words, I know that the laptop wasn't there. In the second example when I pinged the laptop I 84 00:06:38,810 --> 00:06:40,400 got a reply back. 85 00:06:40,400 --> 00:06:42,830 So basically I'm saying hello are you there? 86 00:06:42,830 --> 00:06:47,750 And then the laptop is replying back saying, Yes I'm here and that's why I get a reply back from the 87 00:06:47,750 --> 00:06:52,250 laptop because I configured the laptop with the IP address that the PC is pinging. 88 00:06:52,250 --> 00:06:57,230 So it worked in the second example but notice I'm just seeing the results. 89 00:06:57,240 --> 00:07:04,440 I'm not actually seeing what's going on on the network but if I go to simulation mode what I'll see 90 00:07:04,440 --> 00:07:12,620 now is when I ping the PC it basically pauses packet tracer and I see a packet. 91 00:07:12,720 --> 00:07:14,890 Now I'm not seeing all the options. 92 00:07:14,910 --> 00:07:23,610 I'm going to click here to pop that window out and notice we can see a whole bunch of protocols. 93 00:07:23,700 --> 00:07:30,450 So what we're gonna do is click Show All/None and notice of visible events is now set to None. 94 00:07:30,510 --> 00:07:34,530 If I click that again I'm going to see a whole range of protocols. 95 00:07:34,860 --> 00:07:40,320 We'll talk about what protocols are later but essentially we're going to see a whole bunch of information 96 00:07:40,350 --> 00:07:44,310 which may cause problems when you run packet tracer simulations. 97 00:07:44,430 --> 00:07:50,940 You basically going to overrun packet tracer with messages so click on this option Show All/None and 98 00:07:50,940 --> 00:07:57,960 then go to edit filters and only select the protocols that you need for that specific simulation or 99 00:07:57,960 --> 00:07:59,110 demonstration. 100 00:07:59,160 --> 00:08:06,540 So if you're following me or you're trying things only select specific protocols I know that ping uses 101 00:08:06,570 --> 00:08:08,580 ICMP as an example. 102 00:08:08,880 --> 00:08:14,300 So I'm gonna select that protocol and click close and now I'm going to double click here to pop the 103 00:08:14,310 --> 00:08:15,730 window back in there. 104 00:08:15,840 --> 00:08:21,020 I see this specific packet and I can click next to send it into the network. 105 00:08:21,150 --> 00:08:29,070 I could also do that by popping this window out and clicking play or click this option to go to the 106 00:08:29,100 --> 00:08:32,350 next event in the network. 107 00:08:32,350 --> 00:08:39,419 So notice the packet is now being sent to this PC. If I click back it basically takes me back to the 108 00:08:39,419 --> 00:08:45,610 second event, back takes me to the first event so second event. 109 00:08:45,870 --> 00:08:50,760 third event I can click on the packet to see what's going on. 110 00:08:50,790 --> 00:08:51,750 A lot of detail here. 111 00:08:51,750 --> 00:08:53,530 Don't worry too much about it. 112 00:08:53,610 --> 00:08:59,630 We've got OSI model, we've got Inbound PDU or Protocol Data Unit and Outbound Protocol Data Unit. 113 00:08:59,760 --> 00:09:04,560 We're going to be spending a lot of time discussing what these options meet. 114 00:09:04,560 --> 00:09:07,560 Don't worry too much about it once again for the moment. 115 00:09:07,560 --> 00:09:15,160 So big advice if you don't see the options to UN select protocols click on this little window to pop 116 00:09:15,210 --> 00:09:17,170 the simulation panel out. 117 00:09:17,310 --> 00:09:19,390 Click show all or none. 118 00:09:19,590 --> 00:09:26,160 So we've got all protocols selected now under show no protocols and go to edit filters and I'm only 119 00:09:26,160 --> 00:09:32,340 gonna select the protocols that I want to see which could be set up an ICMP and I'm going to close this 120 00:09:32,340 --> 00:09:36,060 window and now I'll only see those two protocols. 121 00:09:36,060 --> 00:09:37,830 So if I get back to real time 122 00:09:41,420 --> 00:09:46,850 and that ping on the P.C. is now complete it if I do that again. 123 00:09:46,860 --> 00:09:50,460 But before I press enter I'm going to click on simulation. 124 00:09:50,460 --> 00:09:57,130 Notice it's remembered the events that I want to filter and I press enter again. 125 00:09:57,200 --> 00:10:03,310 I see ICMP I'm not seeing opera and there's a reason for that which I won't go into right now. 126 00:10:03,320 --> 00:10:11,630 Basically the PC's remembered information so I don't see OP messages but I don't want to confuse 127 00:10:11,630 --> 00:10:13,880 you at this point so I'll discuss that later. 128 00:10:14,120 --> 00:10:18,380 In a lot of the labs I'm going to tell you to uncheck a whole bunch of protocols and only enable certain 129 00:10:18,380 --> 00:10:24,680 protocols so I'll help you through this but you can always enable certain protocols. 130 00:10:24,710 --> 00:10:30,260 If I'm showing you those in a demonstration and you don't see them OK. 131 00:10:30,310 --> 00:10:36,000 So my big tips are to go to Options preferences miscellaneous. 132 00:10:36,100 --> 00:10:38,800 Make sure that you've clicked this. 133 00:10:38,810 --> 00:10:44,010 Option 2 buffer filtered events only on the interface option. 134 00:10:44,280 --> 00:10:51,540 If you uncheck this always show port labels in logical workspace you won't see the interface names in 135 00:10:51,540 --> 00:10:53,820 your topology so if they missing. 136 00:10:53,820 --> 00:10:57,480 Go to options preferences and select this option. 137 00:10:58,420 --> 00:11:03,130 Again if you struggling with packet tracer doesn't make sense you're not sure how the user interface 138 00:11:03,130 --> 00:11:04,060 works etc.. 139 00:11:04,210 --> 00:11:10,210 I suggest that you go through this course on Cisco's website at least go through some of the modules 140 00:11:10,540 --> 00:11:16,030 so go through chapter one to Chapter 4 so that you learn the basics of the Cisco Packet Tracer interface 141 00:11:17,940 --> 00:11:23,670 you can always ask questions but this will save you a lot of time and a lot of frustration if you understand 142 00:11:23,700 --> 00:11:26,010 the basics of Cisco Packet Tracer.
