1 00:00:00,210 --> 00:00:06,500 Now for the CCNA exam, you really need to know how to configure a wireless LAN controller. 2 00:00:06,510 --> 00:00:09,840 You need to know the menu options in a wireless LAN controller. 3 00:00:09,840 --> 00:00:15,630 So I'm going to show you multiple demonstrations and also test your knowledge of the Cisco Wireless 4 00:00:15,630 --> 00:00:16,620 LAN controller. 5 00:00:17,420 --> 00:00:24,410 In this first demonstration, we're going to build a brand new network consisting of lightweight wireless 6 00:00:24,410 --> 00:00:30,080 access points, wireless LAN controller, switch, DHCP server and obviously clients. 7 00:00:30,350 --> 00:00:35,840 This will give you a good understanding of how to build a network using the Cisco Wireless LAN controller. 8 00:00:35,870 --> 00:00:38,590 I strongly suggest that you follow me. 9 00:00:38,600 --> 00:00:44,990 So while I'm building this, follow what I'm doing and see if you can get it right in the next few labs. 10 00:00:44,990 --> 00:00:50,480 I'm going to test your knowledge and see if you can actually build your own wireless LAN controller 11 00:00:50,480 --> 00:00:51,290 network. 12 00:00:51,650 --> 00:00:57,380 Remember that we're using a lightweight access point share and autonomous access point is an access 13 00:00:57,380 --> 00:01:00,500 point that you configure and manage directly. 14 00:01:00,920 --> 00:01:06,350 Here we're using a lightweight access points which require a wireless LAN controller to work. 15 00:01:06,450 --> 00:01:07,820 Okay, so let's get started. 16 00:01:12,470 --> 00:01:16,520 In this example, I'm controlling that Windows computer from my Mac. 17 00:01:16,670 --> 00:01:21,740 You could run packet tracer directly on your Mac or Linux computer. 18 00:01:21,770 --> 00:01:26,240 I have found however, that I have issues with packet tracer on my Mac. 19 00:01:26,450 --> 00:01:31,970 So I've found that Windows is the most stable using the latest release of packet tracer. 20 00:01:31,970 --> 00:01:34,520 So that's what I'm going to use for this demonstration. 21 00:01:35,160 --> 00:01:36,780 Okay, so let's build a network. 22 00:01:36,800 --> 00:01:38,870 First thing I need is a switch. 23 00:01:38,870 --> 00:01:44,930 So I'm going to get a 3560 switch and add that to the topology. 24 00:01:45,440 --> 00:01:47,930 The switch will simply be a layer two switch. 25 00:01:47,930 --> 00:01:53,270 In this topology, we're going to start with a simple topology, and then in subsequent videos and labs, 26 00:01:53,270 --> 00:01:55,430 we'll build more complex topologies. 27 00:01:55,430 --> 00:01:59,300 But let's start simple to make sure that you can get a network working. 28 00:01:59,870 --> 00:02:01,520 Okay, so we've got a switch. 29 00:02:02,660 --> 00:02:04,670 Next device I need is a PC. 30 00:02:04,700 --> 00:02:08,750 I'm going to use the PC to manage the wireless LAN controller. 31 00:02:08,780 --> 00:02:10,550 I also need a server. 32 00:02:11,030 --> 00:02:17,600 The server will act as a DHCP server to allocate IP addresses to the wireless access points. 33 00:02:18,380 --> 00:02:20,530 We also need a wireless LAN controller. 34 00:02:20,540 --> 00:02:23,960 I'm going to get a 3504 wireless LAN controller. 35 00:02:24,170 --> 00:02:27,320 We also need some lightweight access points. 36 00:02:27,320 --> 00:02:28,820 I'll grab two of those. 37 00:02:28,820 --> 00:02:32,000 So 3702 wireless access points. 38 00:02:32,120 --> 00:02:34,220 So they are our devices. 39 00:02:34,220 --> 00:02:36,410 Let's name this access point one. 40 00:02:36,830 --> 00:02:40,490 We'll name this access point to. 41 00:02:42,660 --> 00:02:45,510 I'll name this w one. 42 00:02:47,080 --> 00:02:48,340 This will be switch one. 43 00:02:49,950 --> 00:02:52,230 I'll leave the rest of the devices as they are. 44 00:02:52,920 --> 00:02:56,400 So next thing is, let's cable up the network. 45 00:02:56,430 --> 00:02:59,760 I'll connect the first Ethernet interface of the PC. 46 00:03:00,980 --> 00:03:04,250 To the first Frost Ethernet interface on the switch. 47 00:03:06,390 --> 00:03:09,360 DHCP server to the second interface. 48 00:03:12,140 --> 00:03:20,450 Wireless LAN controller gigabit one to the third physical interface, and then I'll connect the access 49 00:03:20,450 --> 00:03:23,240 points to the switch. 50 00:03:24,960 --> 00:03:27,450 So there's a basic topology. 51 00:03:27,570 --> 00:03:31,290 It's not very pretty, but that's all we need to get started. 52 00:03:32,460 --> 00:03:35,610 You could make this look better if you wanted to. 53 00:03:35,640 --> 00:03:37,590 I'm not too concerned about that. 54 00:03:37,710 --> 00:03:46,650 One of the things you could do if you don't like the labels is go to options, preferences and uncheck 55 00:03:46,650 --> 00:03:50,610 this option so that the interface labels are removed. 56 00:03:52,140 --> 00:03:57,210 But I prefer having those so that I know how the devices are connected. 57 00:03:57,760 --> 00:04:01,500 Okay, so let's now configure the devices. 58 00:04:01,830 --> 00:04:10,140 The first thing is the wireless access point by default uses an IP address of 1921681.1. 59 00:04:10,290 --> 00:04:14,880 With this subnet mask, I'm going to change that to a slash 24 mask. 60 00:04:15,420 --> 00:04:24,000 I'm going to set the default gateway to 1921681254 and the DNS server. 61 00:04:24,960 --> 00:04:28,080 21921681 253. 62 00:04:28,620 --> 00:04:34,410 So you might want to add a note to your topology so that you know what IP addresses the devices are 63 00:04:34,410 --> 00:04:36,270 using default gateways. 64 00:04:36,270 --> 00:04:42,420 That DHCP server DNS server will be 1921681253. 65 00:04:42,420 --> 00:04:49,480 That will be the server up here and then the wireless LAN controller will be 1921681.1. 66 00:04:49,500 --> 00:04:51,630 I'll leave it at the default for the moment. 67 00:04:51,630 --> 00:04:54,660 Now, in the real world, you probably going to want to change that. 68 00:04:54,660 --> 00:05:00,600 You're going to want to put your access points on a different VLAN to your client devices. 69 00:05:00,600 --> 00:05:02,170 But I'm going to keep it simple. 70 00:05:02,200 --> 00:05:09,300 I always like to keep things simple when we start start from the basics and then bold or iterate on 71 00:05:09,300 --> 00:05:11,490 that and make it more complex. 72 00:05:12,060 --> 00:05:12,330 Okay. 73 00:05:12,330 --> 00:05:17,430 So all I've done is specify the IP addresses of the wireless LAN controller. 74 00:05:17,610 --> 00:05:18,900 We've got its name. 75 00:05:19,410 --> 00:05:21,420 Once again, management information. 76 00:05:21,420 --> 00:05:23,940 Is that on the PC? 77 00:05:23,970 --> 00:05:28,860 We're going to configure it with an IP address in the same subnet. 78 00:05:28,860 --> 00:05:35,070 So let's say 19216815 slash 24 mask. 79 00:05:35,820 --> 00:05:41,760 If you buy a physical access point, it by default will have an IP address of one on 216811. 80 00:05:41,820 --> 00:05:47,610 So you just put your PC in the same subnet and then you can browse to the controller and configure it. 81 00:05:47,610 --> 00:05:49,110 So that's what we're doing here. 82 00:05:49,470 --> 00:05:53,130 So on the PC, I've got my IP address configured, go to desktop. 83 00:05:53,820 --> 00:05:56,430 I'll make this a bit bigger, go to web browser. 84 00:05:56,790 --> 00:06:04,650 And in this example, we're using HTTP and we're going to browse to the IP address of the controller. 85 00:06:04,680 --> 00:06:07,830 Now I have found that this is very slow in packet tracer. 86 00:06:07,830 --> 00:06:11,190 You can see the icons here flickering a lot. 87 00:06:11,460 --> 00:06:12,660 Just be patient. 88 00:06:12,690 --> 00:06:15,660 It might be very slow with this controller. 89 00:06:15,660 --> 00:06:20,100 If you think there's a problem, you could ping from your PC to the controller. 90 00:06:20,490 --> 00:06:25,560 But as you can see here, we've now been prompted with a wizard. 91 00:06:25,590 --> 00:06:27,710 This is something important to remember. 92 00:06:27,770 --> 00:06:31,530 Use HTTP to the IP address of the controller initially. 93 00:06:31,680 --> 00:06:37,830 Then once you've done some initial configuration, it will reboot and you have to use HTTPS to configure 94 00:06:37,830 --> 00:06:38,640 the controller. 95 00:06:38,880 --> 00:06:41,540 So what is the admin name that I'm going to use? 96 00:06:41,550 --> 00:06:44,340 I'm going to use admin password is going to be Cisco. 97 00:06:44,640 --> 00:06:47,130 Now it might complain about that password. 98 00:06:48,420 --> 00:06:52,170 Click start now notice it's complaining about the passwords. 99 00:06:52,170 --> 00:06:55,980 So I'm going to say Cisco one, two, three, Cisco, one, two, three. 100 00:06:56,130 --> 00:07:00,600 Obviously, in the real world, you're going to want to use a better password than that, but that's 101 00:07:00,600 --> 00:07:02,010 fine for this demonstration. 102 00:07:02,010 --> 00:07:04,100 So uppercase C for Cisco. 103 00:07:04,110 --> 00:07:05,130 One, two, three. 104 00:07:05,640 --> 00:07:07,130 Now we need to give it a name. 105 00:07:07,140 --> 00:07:09,670 I'm going to call it wc1. 106 00:07:09,690 --> 00:07:12,030 It's picked up that I'm in the United Kingdom. 107 00:07:12,740 --> 00:07:15,050 Your packet tracer should pick up where you are. 108 00:07:15,080 --> 00:07:18,890 In the real world, you need to specify the right country. 109 00:07:19,280 --> 00:07:25,700 You don't want to use Germany or say Russia in the UK to be legally compliant. 110 00:07:25,730 --> 00:07:27,890 Use the correct country code. 111 00:07:27,920 --> 00:07:31,520 So GB is UK date and time is here. 112 00:07:31,550 --> 00:07:35,450 timeZone is that we can specify http server if we want to. 113 00:07:35,660 --> 00:07:38,220 We're going to specify the management IP address. 114 00:07:38,240 --> 00:07:41,500 I'll keep that the same if you want to change it. 115 00:07:41,510 --> 00:07:43,640 This is where you can change it. 116 00:07:44,730 --> 00:07:47,220 Default gateway to five four. 117 00:07:47,820 --> 00:07:52,650 In the real world, you typically once again want to use VLANs. 118 00:07:52,680 --> 00:07:58,050 You want to separate your AP IP addressing from your clients. 119 00:07:58,140 --> 00:07:59,730 We're not going to worry about that here. 120 00:07:59,760 --> 00:08:00,900 We want to get started. 121 00:08:01,110 --> 00:08:02,280 Somebody click next. 122 00:08:03,480 --> 00:08:10,410 Now we told that we can create a wireless network and employee network, so let's create a staff network. 123 00:08:10,650 --> 00:08:12,720 What security are we going to use? 124 00:08:12,960 --> 00:08:14,400 Make sure you know this. 125 00:08:15,000 --> 00:08:23,400 Pzc WPA two Pzc means we're not using a radius server enterprise means we're going to use a radius server 126 00:08:23,400 --> 00:08:24,980 better for authentication. 127 00:08:24,990 --> 00:08:28,380 Typically at home you're going to use pzc appreciate key. 128 00:08:28,590 --> 00:08:33,960 In other words, the same key or the same password is used on your PC as well as your wireless network. 129 00:08:33,990 --> 00:08:37,740 You're just authenticating use using a preset key. 130 00:08:38,100 --> 00:08:43,140 But if you're using enterprise, you integrate with a radius or tax server. 131 00:08:43,710 --> 00:08:45,930 So I'm simply going to use preset key. 132 00:08:46,620 --> 00:08:48,090 What's the passphrase? 133 00:08:48,090 --> 00:08:53,630 I'm going to use Cisco, one, two, three to keep it simple so that I don't forget my passwords. 134 00:08:53,640 --> 00:08:55,680 You might want to write that down. 135 00:08:55,710 --> 00:08:56,730 Keep it somewhere. 136 00:08:57,120 --> 00:08:59,820 The VLAN that I'm going to use is the management VLAN. 137 00:09:00,120 --> 00:09:04,290 Not great practice for the real world, but we'll leave that for the moment. 138 00:09:04,290 --> 00:09:08,760 We could set up a guest network if we wanted to, but I'm going to show you how to do that manually, 139 00:09:08,760 --> 00:09:11,280 so I'm going to leave that as it is and click next. 140 00:09:11,310 --> 00:09:15,060 Now, a virtual IP address is required by the controller. 141 00:09:15,060 --> 00:09:24,720 In many past implementations they used 1.1.1, but that's now a very important IP address for DNS resolution. 142 00:09:24,720 --> 00:09:29,760 So you don't want to use that Cisco using 192021 by default now. 143 00:09:30,270 --> 00:09:35,730 So that's the virtual IP address default mobility group, which can be used if clients are roaming from 144 00:09:35,730 --> 00:09:38,010 one access point to another is default. 145 00:09:38,010 --> 00:09:40,470 We'll leave that as it is and click next. 146 00:09:41,610 --> 00:09:41,830 Okay. 147 00:09:41,850 --> 00:09:45,180 So now we asked to confirm our settings and click apply. 148 00:09:45,330 --> 00:09:48,540 So there is my controller settings. 149 00:09:48,960 --> 00:09:51,720 Here is my network settings. 150 00:09:51,870 --> 00:09:55,500 I'm using the default virtual IP address and default mobility group. 151 00:09:55,590 --> 00:09:59,670 I'm going to click Apply and notice what we told system will reboot. 152 00:09:59,700 --> 00:10:05,430 After these settings are applied, click okay to apply these configurations or cancel to return to the 153 00:10:05,430 --> 00:10:05,940 wizard. 154 00:10:06,180 --> 00:10:06,870 I'm going to click. 155 00:10:06,870 --> 00:10:07,530 Okay. 156 00:10:07,770 --> 00:10:15,480 The configuration is now saved and I can connect back to the controller, but I need to use HTTPS to 157 00:10:15,480 --> 00:10:17,040 connect to the controller. 158 00:10:17,190 --> 00:10:25,710 So what I could do is on the client, close this down and make sure that I can ping the controller. 159 00:10:25,980 --> 00:10:29,100 So this is one way to check whether it's come back again. 160 00:10:29,730 --> 00:10:32,500 Making sure that the pings actually succeed. 161 00:10:32,520 --> 00:10:38,250 So I'm going to pause the video at this point, wait for this to start working, and then I'll connect 162 00:10:38,250 --> 00:10:40,500 back to the controller using HTTPS. 163 00:10:40,530 --> 00:10:41,480 How are you doing? 164 00:10:41,490 --> 00:10:45,030 Are you able to follow me at this pace? 165 00:10:45,060 --> 00:10:47,870 Are you able to configure your controller? 166 00:10:47,880 --> 00:10:49,140 Try this yourself. 167 00:10:49,140 --> 00:10:50,610 That's the best way to learn.
