WEBVTT 1 00:00.000 --> 00:02.920 Let's go ahead and flip over to the graphical user interface. 2 00:02.920 --> 00:03.560 Here we go. 3 00:03.560 --> 00:08.360 We've got my catalyst 80 or 9800-L wireless controller up here. 4 00:08.360 --> 00:09.520 We're on the dashboard. 5 00:09.520 --> 00:11.800 We see a lot of great information at a glance 6 00:11.800 --> 00:13.680 here about the number of radios we have, which 7 00:13.680 --> 00:17.000 is zero across the board, as well as our wireless networks. 8 00:17.000 --> 00:18.240 It's great that they're up. 9 00:18.240 --> 00:20.920 But we have zero wireless LANs and zero access points 10 00:20.920 --> 00:22.360 and so on and so forth. 11 00:22.360 --> 00:24.360 So this is a very fresh configuration 12 00:24.360 --> 00:26.160 of a wireless LAN controller. 13 00:26.160 --> 00:28.760 Now, a lot of the configurations we might imagine 14 00:28.760 --> 00:31.800 will be under configuration, but we open it up wholly, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 14 00:28.760 --> 00:31.800 will be under configuration, but we open it up wholly, 15 00:31.800 --> 00:32.320 moly. 16 00:32.320 --> 00:35.840 There is a lot of different configurations in here. 17 00:35.840 --> 00:37.800 And so this is going to take us a little while 18 00:37.800 --> 00:39.000 to learn our way around. 19 00:39.000 --> 00:41.720 I will say that the good news is that we don't really 20 00:41.720 --> 00:45.360 use a ton of these options outside of the nitty gritty 21 00:45.360 --> 00:48.400 of fine-tuning enterprise networks. 22 00:48.400 --> 00:51.760 So for the purpose of the scope of this course and this exam, 23 00:51.760 --> 00:54.960 we're only going to need to know a couple of options in here 24 00:54.960 --> 00:57.120 and we'll be covering each of those thoroughly. 25 00:57.120 --> 00:58.960 So the first thing we're going to do is pay attention 26 00:58.960 --> 01:00.240 to the interfaces. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 26 00:58.960 --> 01:00.240 to the interfaces. 27 01:00.240 --> 01:02.920 We have to make sure our interfaces are properly configured. 28 01:02.920 --> 01:05.680 Logical would be things like our port channels, 29 01:05.680 --> 01:08.520 as well as the loopback interfaces. 30 01:08.520 --> 01:12.240 We might expect the SVI's to be under here, but they're not. 31 01:12.240 --> 01:15.120 So instead, we can come here-- 32 01:15.120 --> 01:16.800 we can just look here, I suppose-- 33 01:16.800 --> 01:19.320 see that we configure port channels and loopbacks. 34 01:19.320 --> 01:21.320 I can also come over here and see that we've 35 01:21.320 --> 01:24.440 got ethernet interfaces. 36 01:24.440 --> 01:28.000 And so this is all the ethernet interfaces on this device. 37 01:28.000 --> 01:32.680 There are four physical front-facing 2GIG ports on here. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 37 01:28.000 --> 01:32.680 There are four physical front-facing 2GIG ports on here. 38 01:32.680 --> 01:35.200 And then we've got a couple of 10GIG ports that 39 01:35.200 --> 01:37.800 are intended to be used for upstream connectivity. 40 01:37.800 --> 01:40.960 But really, we can use any of these ports for anything. 41 01:40.960 --> 01:44.800 And then this gig zero is actually the service port. 42 01:44.800 --> 01:48.160 So once again, we see that .12 IP address that's showing up 43 01:48.160 --> 01:48.920 there. 44 01:48.920 --> 01:54.400 So what I want to do is I want to configure 2GIG ethernet 0/0/0. 45 01:54.400 --> 01:55.840 This would be that connection that's 46 01:55.840 --> 01:59.080 going out to the rest of my network. 47 01:59.080 --> 02:01.520 I just want to make sure it's in the right VLAN. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 47 01:59.080 --> 02:01.520 I just want to make sure it's in the right VLAN. 48 02:01.520 --> 02:06.720 So I'm going to also bring it online, leave it as a trunk, 49 02:06.720 --> 02:09.360 and we'll allow VLANs 2 through 10. 50 02:09.360 --> 02:09.840 Why not? 51 02:09.840 --> 02:11.440 That's perfectly fine. 52 02:11.440 --> 02:13.480 I don't have any VLANs in my environment, however. 53 02:13.480 --> 02:15.960 So I'm just going to say that the native VLAN is 10. 54 02:15.960 --> 02:17.360 And hopefully, everything works there. 55 02:17.360 --> 02:19.960 In fact, just to make sure we don't get any CDP errors 56 02:19.960 --> 02:24.360 or anything, I'm just going to only allow the native VLAN here. 57 02:24.360 --> 02:27.400 And we'll bring that port online. 58 02:27.400 --> 02:29.400 So that's great that it's online. 59 02:29.400 --> 02:32.520 However, now we need to go and configure the SVI. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 59 02:29.400 --> 02:32.520 However, now we need to go and configure the SVI. 60 02:32.520 --> 02:34.680 So where would we think the SVI would be? 61 02:34.680 --> 02:36.120 I would certainly always think it'd 62 02:36.120 --> 02:37.800 be under the logical side, but we've already 63 02:37.800 --> 02:39.680 said that's not where it is. 64 02:39.680 --> 02:41.880 Weirdly, it's under VLANs. 65 02:41.880 --> 02:43.320 I know you say, well, why is it weird? 66 02:43.320 --> 02:45.080 An SVI is a VLAN interface. 67 02:45.080 --> 02:46.960 Well, it's weird because it's under layer 2. 68 02:46.960 --> 02:49.600 And an SVI is definitely not layer 2. 69 02:49.600 --> 02:51.040 And yet, here we are. 70 02:51.040 --> 02:53.880 So we're going to go to layer 2, then the VLAN, 71 02:53.880 --> 02:57.280 and then the first tab happens to be something that's layer 3. 72 02:57.280 --> 02:58.960 Again, layer 2, layer 3. 73 02:58.960 --> 03:00.200 OK, so be it. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 73 02:58.960 --> 03:00.200 OK, so be it. 74 03:00.200 --> 03:00.920 I'll get over it. 75 03:00.920 --> 03:04.320 So either way, if I need to configure my VLANs, 76 03:04.320 --> 03:05.160 I can come over here. 77 03:05.160 --> 03:08.880 We see I've already got those VLANs 2 through 10 configured. 78 03:08.880 --> 03:12.960 But I'm going to come back to the SVI here, say Add. 79 03:12.960 --> 03:16.000 And I can add an SVI for VLAN 10. 80 03:16.000 --> 03:18.240 So admin status is up. 81 03:18.240 --> 03:21.240 And oh, by the way, one thing that as we go through all 82 03:21.240 --> 03:25.280 of this you might find is that these configuration prompts, 83 03:25.280 --> 03:27.240 everything that we're doing in here, 84 03:27.240 --> 03:30.520 it's going to feel very familiar if we are comfortable WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 84 03:27.240 --> 03:30.520 it's going to feel very familiar if we are comfortable 85 03:30.520 --> 03:33.280 with iOSXE CLI commands. 86 03:33.280 --> 03:36.360 Because everything on here, the VLAN number, 87 03:36.360 --> 03:38.640 if I'm going to configure an SVI at the CLI, 88 03:38.640 --> 03:41.120 I'm going to say interface VLAN 10, right? 89 03:41.120 --> 03:42.080 So there you go. 90 03:42.080 --> 03:43.640 I can enter an interface description. 91 03:43.640 --> 03:45.640 I can do a shut or a no shut. 92 03:45.640 --> 03:47.200 And I can add a VRF. 93 03:47.200 --> 03:50.400 I can configure-- like all of these configurations 94 03:50.400 --> 03:55.800 are the configurations that I would use on the SVI in CLI. 95 03:55.800 --> 03:58.320 Yeah, however you want to say, via the CLI. 96 03:58.320 --> 04:02.120 And so this is a really fascinating way WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 96 03:58.320 --> 04:02.120 And so this is a really fascinating way 97 04:02.120 --> 04:06.480 of recognizing that this is really all the same interface. 98 04:06.480 --> 04:08.120 It's the graphical user interface. 99 04:08.120 --> 04:09.120 It's the CLI. 100 04:09.120 --> 04:10.560 It's one and the same. 101 04:10.560 --> 04:12.120 And it doesn't matter which one we use. 102 04:12.120 --> 04:16.600 We can absolutely configure this via the CLI if we so desire. 103 04:16.600 --> 04:19.720 So I'm going to check the IPv4 box here and say, OK, 104 04:19.720 --> 04:22.200 I'm going to add an IPv4 address. 105 04:22.200 --> 04:24.560 So again, I could configure it for DHCP. 106 04:24.560 --> 04:26.240 I'm going to configure it for static. 107 04:26.240 --> 04:29.840 Give it that 192.168.50. 108 04:29.840 --> 04:32.000 And we said we're going to use .13. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 108 04:29.840 --> 04:32.000 And we said we're going to use .13. 109 04:32.000 --> 04:36.400 Subnet mask is /24. 110 04:36.400 --> 04:37.640 I could add a secondary IP. 111 04:37.640 --> 04:39.240 Again, all of these configurations 112 04:39.240 --> 04:42.000 are just the exact configurations I would use 113 04:42.000 --> 04:44.440 if I was configuring this on the CLI. 114 04:44.440 --> 04:47.440 So I'm going to go ahead and apply this to the device. 115 04:47.440 --> 04:52.600 And we should now see that our VLAN 10 interface is up and up. 116 04:52.600 --> 04:55.280 Now, just to prove my point here, I'm switching over 117 04:55.280 --> 04:57.720 to take a look at the CLI here. 118 04:57.720 --> 05:02.720 And so I am now logged into the wireless LAN controller via CLI. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 118 04:57.720 --> 05:02.720 And so I am now logged into the wireless LAN controller via CLI. 119 05:02.720 --> 05:05.560 This is again going to feel like it's a switch. 120 05:05.560 --> 05:09.000 If I do a show VLAN, I get the show VLAN commands. 121 05:09.000 --> 05:12.320 If I were to, I don't know, do a show version, 122 05:12.320 --> 05:13.880 I can look at the version. 123 05:13.880 --> 05:17.880 See, it's a 9800 up there and 9800-L here. 124 05:17.880 --> 05:21.560 All of these commands are exactly what they would be 125 05:21.560 --> 05:23.440 on an iOS XE device. 126 05:23.440 --> 05:25.200 So if I do a show run, for example, 127 05:25.200 --> 05:29.360 I'm going to see a lot of configuration around the-- 128 05:29.360 --> 05:30.640 or that feels like a switch. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 128 05:29.360 --> 05:30.640 or that feels like a switch. 129 05:30.640 --> 05:33.080 This feels exactly like a switch to me. 130 05:33.080 --> 05:34.760 Other than eventually, we do start 131 05:34.760 --> 05:37.880 getting to some wireless specific configurations. 132 05:37.880 --> 05:39.480 So as we tap a space through here, 133 05:39.480 --> 05:40.840 what we're going to find, first of all, 134 05:40.840 --> 05:45.120 look at this, that interface 2GIG 0/0/0/0. 135 05:45.120 --> 05:48.280 Remember, I configured it with a VLAN allowed list of 10, 136 05:48.280 --> 05:50.400 a native VLAN of 10. 137 05:50.400 --> 05:53.600 It just put it into the CLI for me, which I think is pretty fun. 138 05:53.600 --> 05:56.800 I just configured an interface VLAN 10. 139 05:56.800 --> 05:59.960 And so apparently, I had a secondary address on there already 140 05:59.960 --> 06:01.800 from previously. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 140 05:59.960 --> 06:01.800 from previously. 141 06:01.800 --> 06:03.000 We'll just ignore that. 142 06:03.000 --> 06:08.160 But I do have this 50.13 address, which we just added. 143 06:08.160 --> 06:10.160 And so that's pretty cool as well. 144 06:10.160 --> 06:12.120 And then we've spaced down to the bottom, 145 06:12.120 --> 06:15.240 was where we get into a lot of the wireless configurations. 146 06:15.240 --> 06:17.920 And again, we don't need to worry too much about this right 147 06:17.920 --> 06:18.440 now. 148 06:18.440 --> 06:20.440 And ultimately, we're really not going 149 06:20.440 --> 06:23.720 to be asked about anything from a CLI configuration, 150 06:23.720 --> 06:26.360 because this isn't a wireless exam. 151 06:26.360 --> 06:29.000 This is an enterprise networking exam 152 06:29.000 --> 06:32.120 that's asking us to understand some things about wireless. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 152 06:29.000 --> 06:32.120 that's asking us to understand some things about wireless. 153 06:32.120 --> 06:34.080 And yes, we'll have to do some configuration. 154 06:34.080 --> 06:36.080 But for the most part, that configuration 155 06:36.080 --> 06:39.080 will be via the Graphical User Interface. 156 06:39.080 --> 06:41.960 OK, so back to the 9800-- 157 06:41.960 --> 06:44.800 well, we were already on the 9800. 158 06:44.800 --> 06:47.040 But now we're back to the Graphical User Interface. 159 06:47.040 --> 06:50.720 I'm going to come back to the dashboard here and check it out. 160 06:50.720 --> 06:53.440 We actually see that we have an access point. 161 06:53.440 --> 06:55.680 Now, it says that it's not joined. 162 06:55.680 --> 06:58.440 If I look at the access point here, 163 06:58.440 --> 07:01.160 we'll notice that it's flashing blue. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 163 06:58.440 --> 07:01.160 we'll notice that it's flashing blue. 164 07:01.160 --> 07:03.080 Well, I don't know how clearly that's coming through. 165 07:03.080 --> 07:05.240 But it's a different color than it was before. 166 07:05.240 --> 07:08.080 It's telling me that it's updating that access point. 167 07:08.080 --> 07:11.640 It's pushing configuration-- or software version down. 168 07:11.640 --> 07:13.720 And that software is going to update. 169 07:13.720 --> 07:15.440 And eventually, the access point will join. 170 07:15.440 --> 07:17.880 And we'll have our access point online. 171 07:17.880 --> 07:19.400 So let's give it a few minutes here 172 07:19.400 --> 07:21.520 and make sure that it attaches appropriately. 173 07:21.520 --> 07:26.920 And from there, we'll see what comes next, I suppose. 174 07:26.920 --> 07:28.320 All right, and that just took a few minutes 175 07:28.320 --> 07:30.120 to finish the software update. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 175 07:28.320 --> 07:30.120 to finish the software update. 176 07:30.120 --> 07:32.880 But now we see that we do have it online. 177 07:32.880 --> 07:35.520 I can see that I have an access point up here. 178 07:35.520 --> 07:39.280 I've got the networks online, 1/6 gigahertz radio. 179 07:39.280 --> 07:41.480 Remember, this access point actually has 2/5 gigahertz 180 07:41.480 --> 07:44.120 radio, so just that 1 AP has them both. 181 07:44.120 --> 07:46.880 We see 1 is in an upstate, 1 is not. 182 07:46.880 --> 07:49.680 And then we've got the 2.4 gigahertz as well. 183 07:49.680 --> 07:51.480 If I hold this AP up one more time, 184 07:51.480 --> 07:55.080 we can maybe hopefully see that the light is now solid green, 185 07:55.080 --> 07:58.000 indicating that it is online and functional. 186 07:58.000 --> 08:00.480 So as we consider what we just did, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 186 07:58.000 --> 08:00.480 So as we consider what we just did, 187 08:00.480 --> 08:03.840 it's really about the fact that we need a termination point 188 08:03.840 --> 08:05.160 for cap web tunnels. 189 08:05.160 --> 08:08.440 On the 9800, the role or the interface 190 08:08.440 --> 08:11.600 that we're going to use for that is going to be the SVI. 191 08:11.600 --> 08:13.200 And so we configured our SVI. 192 08:13.200 --> 08:15.080 We made sure it was layer two reachable. 193 08:15.080 --> 08:16.800 And in an enterprise environment, 194 08:16.800 --> 08:18.880 we probably wouldn't rely on layer two broadcast. 195 08:18.880 --> 08:21.680 Instead, we'd probably use DHCP option 43, 196 08:21.680 --> 08:24.280 or possibly DNS to point to that IP address. 197 08:24.280 --> 08:27.120 And either way, as long as that IP address is online 198 08:27.120 --> 08:29.640 and functional and reachable, then our access points 199 08:29.640 --> 08:31.760 will be able to connect to the wireless LAN controller WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 199 08:29.640 --> 08:31.760 will be able to connect to the wireless LAN controller 200 08:31.760 --> 08:33.360 inform those CAP web tunnels.
