0:00:03.000000 --> 0:00:08.240000
 Hello and welcome to this video titled
 Cisco Wireless Land Controllers.

0:00:08.240000 --> 0:00:10.860000
 In this video I'm going to go over the
 different categories of wireless

0:00:10.860000 --> 0:00:12.040000
 land controllers.

0:00:12.040000 --> 0:00:14.740000
 Specifically we're going to talk about
 at a real high level the differences

0:00:14.740000 --> 0:00:20.540000
 between physical controllers, cloud-based
 controllers, and embedded wireless.

0:00:20.540000 --> 0:00:25.360000
 And then lastly what is
 Cisco Mobility Express?

0:00:25.360000 --> 0:00:30.140000
 So as the topic side said when you
 decide for yourself okay I want to

0:00:30.140000 --> 0:00:33.280000
 have a wireless land controller
 to control my access points.

0:00:33.280000 --> 0:00:35.960000
 I don't want to deal with
 autonomous access points.

0:00:35.960000 --> 0:00:39.040000
 I want to control and manage
 them via a controller.

0:00:39.040000 --> 0:00:43.480000
 Well now you have to decide which category
 of these four do you want.

0:00:43.480000 --> 0:00:46.220000
 Let's just real quickly go over these
 so you have a better understanding

0:00:46.220000 --> 0:00:49.120000
 of what they are and that might help
 you in your purchasing and design

0:00:49.120000 --> 0:00:52.400000
 decision. Let's start out
 with physical controllers.

0:00:52.400000 --> 0:00:55.940000
 So this is very popular clearly this
 is something you can touch and feel

0:00:55.940000 --> 0:00:57.520000
 and rack mount yourself.

0:00:57.520000 --> 0:01:02.500000
 It provides a dedicated appliance for
 wireless land access point control.

0:01:02.500000 --> 0:01:05.540000
 So this is a physical box that you
 will purchase that will be shipped

0:01:05.540000 --> 0:01:07.820000
 to you and then you'll have to rack mount
 it somewhere in your data center

0:01:07.820000 --> 0:01:09.480000
 or something like that.

0:01:09.480000 --> 0:01:12.600000
 Now one of the great things about physical
 controllers is you have absolute

0:01:12.600000 --> 0:01:15.920000
 total control over this thing.

0:01:15.920000 --> 0:01:18.540000
 You get to decide what features
 you want to turn on and off.

0:01:18.540000 --> 0:01:22.440000
 You get to decide when or if you're
 going to upgrade the software, where

0:01:22.440000 --> 0:01:26.080000
 you're going to install
 it, it's all up to you.

0:01:26.080000 --> 0:01:30.200000
 And typically your physical controllers
 these appliances as it says here

0:01:30.200000 --> 0:01:34.180000
 will provide you with the greatest quantity
 of features that are available

0:01:34.180000 --> 0:01:37.240000
 of all your different types of
 wireless land controllers.

0:01:37.240000 --> 0:01:40.720000
 So currently as of this recording these
 are the wireless land controllers

0:01:40.720000 --> 0:01:45.440000
 that Cisco sells and they vary
 typically in their form factor.

0:01:45.440000 --> 0:01:49.400000
 For example many of these are only
 one rack unit wide so they're very

0:01:49.400000 --> 0:01:53.260000
 small. Some of them are two
 or three rack units wide.

0:01:53.260000 --> 0:01:58.220000
 They also vary typically in the quantity
 of access points and clients

0:01:58.220000 --> 0:02:00.420000
 that they can support.

0:02:00.420000 --> 0:02:03.600000
 So for example if you take a look at
 your larger ones here for example

0:02:03.600000 --> 0:02:10.960000
 the 9800 series and the 8540 with the
 9800 series the biggest one you

0:02:10.960000 --> 0:02:13.860000
 would get currently is the 98-80.

0:02:13.860000 --> 0:02:20.200000
 Now both the 98-80 and the 8540
 they support a lot of stuff.

0:02:20.200000 --> 0:02:24.440000
 They support up to 6
,000 access points.

0:02:24.440000 --> 0:02:29.540000
 Up to 6,000 APs can be supported
 by one controller.

0:02:29.540000 --> 0:02:39.220000
 And you can have up to 6,400 clients
 serviced by a single access point.

0:02:39.220000 --> 0:02:43.700000
 One other differentiator among these
 access points is you're always going

0:02:43.700000 --> 0:02:49.160000
 to have some sort of wired ports for connectivity
 to the wired distribution

0:02:49.160000 --> 0:02:52.420000
 system which is your switch.

0:02:52.420000 --> 0:02:57.720000
 Now depending on the model we'll determine
 how fast those ports are and

0:02:57.720000 --> 0:02:59.540000
 how many of those ports you have.

0:02:59.540000 --> 0:03:09.900000
 So for example the 9800-80 that can support
 up to 80 gigabits per second.

0:03:09.900000 --> 0:03:13.620000
 So those are some of the differentiating
 factors of physical controllers

0:03:13.620000 --> 0:03:15.240000
 that you will find.

0:03:15.240000 --> 0:03:20.680000
 Alright and alternative option is
 to use cloud-based controllers.

0:03:20.680000 --> 0:03:24.040000
 So the notion of a cloud-based controller
 is usually one that's available

0:03:24.040000 --> 0:03:26.380000
 via an internet connection.

0:03:26.380000 --> 0:03:29.780000
 So that would be Miraki's
 wireless cloud service.

0:03:29.780000 --> 0:03:32.980000
 As you can see here they advertise
 that scales to support an unlimited

0:03:32.980000 --> 0:03:35.640000
 number of access points
 in clients.

0:03:35.640000 --> 0:03:39.240000
 It does require that you have a subscription
 to the Miraki cloud service

0:03:39.240000 --> 0:03:42.820000
 and this typically only supports
 Miraki products.

0:03:42.820000 --> 0:03:47.720000
 So if you look on Cisco's website there
 are Miraki access points and there

0:03:47.720000 --> 0:03:49.180000
 are Cisco access points.

0:03:49.180000 --> 0:03:53.460000
 So you would use Miraki's wireless
 cloud service to manage your Miraki

0:03:53.460000 --> 0:03:59.140000
 access points. Alternatively another
 type of cloud-based controller is

0:03:59.140000 --> 0:04:02.340000
 the Cisco Catalyst 9800-CL.

0:04:02.340000 --> 0:04:08.880000
 So the 9800-CL is the exact same software
 that you would get in your physical

0:04:08.880000 --> 0:04:13.300000
 9800. So if you were to buy a catalyst
 9800 physical box that we just

0:04:13.300000 --> 0:04:18.560000
 saw on the previous page its features
 and functionality are exactly the

0:04:18.560000 --> 0:04:20.620000
 same as the 9800-CL.

0:04:20.620000 --> 0:04:24.400000
 The CL in this case stands for
 cloud and you can guess.

0:04:24.400000 --> 0:04:27.860000
 So this is advertised that you can use
 this to install this in a public

0:04:27.860000 --> 0:04:29.360000
 or a private cloud.

0:04:29.360000 --> 0:04:30.980000
 This is not a physical box.

0:04:30.980000 --> 0:04:32.840000
 This is a software image.

0:04:32.840000 --> 0:04:38.620000
 So you can install it in AWS, KVM or
 VMware and it's packaged as a virtual

0:04:38.620000 --> 0:04:43.760000
 machine. You can see it also supports
 up to 6,000 access points.

0:04:43.760000 --> 0:04:46.080000
 And 64,000 clients.

0:04:46.080000 --> 0:04:48.180000
 So I think I made a mistake
 on the previous slide.

0:04:48.180000 --> 0:04:51.180000
 I said 6,400 clients.

0:04:51.180000 --> 0:04:56.700000
 No, the 9800-80 can support
 up to 64,000 clients.

0:04:56.700000 --> 0:04:59.820000
 A lot of stuff. Okay, there's
 another option.

0:04:59.820000 --> 0:05:03.360000
 So I could have a physical
 controller as an appliance.

0:05:03.360000 --> 0:05:06.500000
 I could have a cloud-based controller
 that I don't actually see that's

0:05:06.500000 --> 0:05:08.020000
 just software-based.

0:05:08.020000 --> 0:05:11.320000
 Or alternatively I could do something
 called embedded wireless.

0:05:11.320000 --> 0:05:14.520000
 Which means that your wireless LAN controller
 functionality is actually

0:05:14.520000 --> 0:05:17.320000
 embedded within another
 network device.

0:05:17.320000 --> 0:05:19.100000
 Typically a switch.

0:05:19.100000 --> 0:05:24.260000
 So that same Cisco 9800 and all of
 its features can be embedded within

0:05:24.260000 --> 0:05:27.100000
 a KALIS 9300 switch.

0:05:27.100000 --> 0:05:31.980000
 Supports up to 200 access
 points and 4,000 clients.

0:05:31.980000 --> 0:05:36.940000
 Now lastly, there is a fourth method
 of controlling your access points.

0:05:36.940000 --> 0:05:42.220000
 We could have one access point,
 control another access point.

0:05:42.220000 --> 0:05:45.180000
 And this is called Cisco
 Mobility Express.

0:05:45.180000 --> 0:05:49.540000
 Where there are certain versions or
 models of Cisco access points that

0:05:49.540000 --> 0:05:55.660000
 can have other access points, it
 can control other access points.

0:05:55.660000 --> 0:06:00.640000
 So one AP can serve as a wireless LAN controller
 for up to 100 other lightweight

0:06:00.640000 --> 0:06:04.780000
 access points. So there are
 certain models that do this.

0:06:04.780000 --> 0:06:09.280000
 For example, in this graphic that you
 see down here, we've got the Cisco

0:06:09.280000 --> 0:06:13.320000
 Aeronet 1815s. Those support this.


0:06:13.320000 --> 0:06:16.040000
 The 1830 supports that.

0:06:16.040000 --> 0:06:21.480000
 The 1850 and the 2800 series
 of access points.

0:06:21.480000 --> 0:06:26.880000
 All those Aeronaut models support
 Cisco Mobility Express.

0:06:26.880000 --> 0:06:32.960000
 Now, when you do this, you can actually
 also have more than one.

0:06:32.960000 --> 0:06:36.180000
 So you have multiple mobility express
 controllers and one will be elected

0:06:36.180000 --> 0:06:40.060000
 as basically the active one that services
 all the other lightweight access

0:06:40.060000 --> 0:06:43.380000
 points. The other ones will
 be like a standby state.

0:06:43.380000 --> 0:06:45.120000
 So you can see right here.

0:06:45.120000 --> 0:06:47.720000
 And notice, this is special
 software image.

0:06:47.720000 --> 0:06:51.620000
 So this will replace the normal capwap
 image that the access point would

0:06:51.620000 --> 0:06:56.020000
 normally have to form capwap
 tunnels with a controller.

0:06:56.020000 --> 0:06:58.620000
 No special licenses required.

0:06:58.620000 --> 0:07:01.180000
 So that is Cisco Mobility Express.


0:07:01.180000 --> 0:07:04.860000
 And that, my friends, concludes this video
 on the different types of controllers

0:07:04.860000 --> 0:07:06.040000
 that are available.
