Let's go ahead and flip over to the graphical user interface.
Here we go.
We've got my catalyst 80 or 9800-L wireless controller up here.
We're on the dashboard.
We see a lot of great information at a glance
here about the number of radios we have, which
is zero across the board, as well as our wireless networks.
It's great that they're up.
But we have zero wireless LANs and zero access points
and so on and so forth.
So this is a very fresh configuration
of a wireless LAN controller.
Now, a lot of the configurations we might imagine
will be under configuration, but we open it up wholly, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
will be under configuration, but we open it up wholly,
moly.
There is a lot of different configurations in here.
And so this is going to take us a little while
to learn our way around.
I will say that the good news is that we don't really
use a ton of these options outside of the nitty gritty
of fine-tuning enterprise networks.
So for the purpose of the scope of this course and this exam,
we're only going to need to know a couple of options in here
and we'll be covering each of those thoroughly.
So the first thing we're going to do is pay attention
to the interfaces. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
to the interfaces.
We have to make sure our interfaces are properly configured.
Logical would be things like our port channels,
as well as the loopback interfaces.
We might expect the SVI's to be under here, but they're not.
So instead, we can come here--
we can just look here, I suppose--
see that we configure port channels and loopbacks.
I can also come over here and see that we've
got ethernet interfaces.
And so this is all the ethernet interfaces on this device.
There are four physical front-facing 2GIG ports on here. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
There are four physical front-facing 2GIG ports on here.
And then we've got a couple of 10GIG ports that
are intended to be used for upstream connectivity.
But really, we can use any of these ports for anything.
And then this gig zero is actually the service port.
So once again, we see that .12 IP address that's showing up
there.
So what I want to do is I want to configure 2GIG ethernet 0/0/0.
This would be that connection that's
going out to the rest of my network.
I just want to make sure it's in the right VLAN. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
I just want to make sure it's in the right VLAN.
So I'm going to also bring it online, leave it as a trunk,
and we'll allow VLANs 2 through 10.
Why not?
That's perfectly fine.
I don't have any VLANs in my environment, however.
So I'm just going to say that the native VLAN is 10.
And hopefully, everything works there.
In fact, just to make sure we don't get any CDP errors
or anything, I'm just going to only allow the native VLAN here.
And we'll bring that port online.
So that's great that it's online.
However, now we need to go and configure the SVI. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
However, now we need to go and configure the SVI.
So where would we think the SVI would be?
I would certainly always think it'd
be under the logical side, but we've already
said that's not where it is.
Weirdly, it's under VLANs.
I know you say, well, why is it weird?
An SVI is a VLAN interface.
Well, it's weird because it's under layer 2.
And an SVI is definitely not layer 2.
And yet, here we are.
So we're going to go to layer 2, then the VLAN,
and then the first tab happens to be something that's layer 3.
Again, layer 2, layer 3.
OK, so be it. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
OK, so be it.
I'll get over it.
So either way, if I need to configure my VLANs,
I can come over here.
We see I've already got those VLANs 2 through 10 configured.
But I'm going to come back to the SVI here, say Add.
And I can add an SVI for VLAN 10.
So admin status is up.
And oh, by the way, one thing that as we go through all
of this you might find is that these configuration prompts,
everything that we're doing in here,
it's going to feel very familiar if we are comfortable WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
it's going to feel very familiar if we are comfortable
with iOSXE CLI commands.
Because everything on here, the VLAN number,
if I'm going to configure an SVI at the CLI,
I'm going to say interface VLAN 10, right?
So there you go.
I can enter an interface description.
I can do a shut or a no shut.
And I can add a VRF.
I can configure-- like all of these configurations
are the configurations that I would use on the SVI in CLI.
Yeah, however you want to say, via the CLI.
And so this is a really fascinating way WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And so this is a really fascinating way
of recognizing that this is really all the same interface.
It's the graphical user interface.
It's the CLI.
It's one and the same.
And it doesn't matter which one we use.
We can absolutely configure this via the CLI if we so desire.
So I'm going to check the IPv4 box here and say, OK,
I'm going to add an IPv4 address.
So again, I could configure it for DHCP.
I'm going to configure it for static.
Give it that 192.168.50.
And we said we're going to use .13. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And we said we're going to use .13.
Subnet mask is /24.
I could add a secondary IP.
Again, all of these configurations
are just the exact configurations I would use
if I was configuring this on the CLI.
So I'm going to go ahead and apply this to the device.
And we should now see that our VLAN 10 interface is up and up.
Now, just to prove my point here, I'm switching over
to take a look at the CLI here.
And so I am now logged into the wireless LAN controller via CLI. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And so I am now logged into the wireless LAN controller via CLI.
This is again going to feel like it's a switch.
If I do a show VLAN, I get the show VLAN commands.
If I were to, I don't know, do a show version,
I can look at the version.
See, it's a 9800 up there and 9800-L here.
All of these commands are exactly what they would be
on an iOS XE device.
So if I do a show run, for example,
I'm going to see a lot of configuration around the--
or that feels like a switch. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
or that feels like a switch.
This feels exactly like a switch to me.
Other than eventually, we do start
getting to some wireless specific configurations.
So as we tap a space through here,
what we're going to find, first of all,
look at this, that interface 2GIG 0/0/0/0.
Remember, I configured it with a VLAN allowed list of 10,
a native VLAN of 10.
It just put it into the CLI for me, which I think is pretty fun.
I just configured an interface VLAN 10.
And so apparently, I had a secondary address on there already
from previously. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
from previously.
We'll just ignore that.
But I do have this 50.13 address, which we just added.
And so that's pretty cool as well.
And then we've spaced down to the bottom,
was where we get into a lot of the wireless configurations.
And again, we don't need to worry too much about this right
now.
And ultimately, we're really not going
to be asked about anything from a CLI configuration,
because this isn't a wireless exam.
This is an enterprise networking exam
that's asking us to understand some things about wireless. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
that's asking us to understand some things about wireless.
And yes, we'll have to do some configuration.
But for the most part, that configuration
will be via the Graphical User Interface.
OK, so back to the 9800--
well, we were already on the 9800.
But now we're back to the Graphical User Interface.
I'm going to come back to the dashboard here and check it out.
We actually see that we have an access point.
Now, it says that it's not joined.
If I look at the access point here,
we'll notice that it's flashing blue. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
we'll notice that it's flashing blue.
Well, I don't know how clearly that's coming through.
But it's a different color than it was before.
It's telling me that it's updating that access point.
It's pushing configuration-- or software version down.
And that software is going to update.
And eventually, the access point will join.
And we'll have our access point online.
So let's give it a few minutes here
and make sure that it attaches appropriately.
And from there, we'll see what comes next, I suppose.
All right, and that just took a few minutes
to finish the software update. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
to finish the software update.
But now we see that we do have it online.
I can see that I have an access point up here.
I've got the networks online, 1/6 gigahertz radio.
Remember, this access point actually has 2/5 gigahertz
radio, so just that 1 AP has them both.
We see 1 is in an upstate, 1 is not.
And then we've got the 2.4 gigahertz as well.
If I hold this AP up one more time,
we can maybe hopefully see that the light is now solid green,
indicating that it is online and functional.
So as we consider what we just did, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So as we consider what we just did,
it's really about the fact that we need a termination point
for cap web tunnels.
On the 9800, the role or the interface
that we're going to use for that is going to be the SVI.
And so we configured our SVI.
We made sure it was layer two reachable.
And in an enterprise environment,
we probably wouldn't rely on layer two broadcast.
Instead, we'd probably use DHCP option 43,
or possibly DNS to point to that IP address.
And either way, as long as that IP address is online
and functional and reachable, then our access points
will be able to connect to the wireless LAN controller WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
will be able to connect to the wireless LAN controller
inform those CAP web tunnels.
