Hello, everyone.

Ferney Muñoz with Wireless LAN Professionals.

Cambium XV3-8

Let’s talk a little bit about it.

Cambium XV3-8

That’s a Wi-Fi 6 802.11ax, 8x8x8

access point from Cambium Networks,

This video is in no way sponsored by Cambium.

Neither is it a comprehensive set of instructions

on how to configure properly.

This is just to share with you my first impression.

The device can be configured multiple ways.

You can manage it with xms cloud.

Or with the cnMaestro

which is the cloud management for

Cambium Networks

And it can also be managed as a standalone device.

This is the approach I’m going to take.

By default it is set on the

192.168.0 network with 24 bitmask

I’m going to join it to my local network

which is 192.168.128

Using this application LanScan Pro

I’m going to scan the network

The last four of the Mac address of this device

is “dc:0c” so it obtained that one “37”

So now let’s go over to my browser

I will use that IP address 137.

And the default username and password is just

“admin” “admin” Very simple.

And once I go in

the dashboard provides plenty of information

if I have any clients connected

what channels am I using on 2.4 and 5 GHz

I don’t have MGIG ports in my network

I only have 1GIG so it is getting 1GB connection

And it’s showing that both radios

2.4 and 5 are up and running.

Here on the access point info we have

model software Mac address the hostname

Uptime, some resources

And yes, this is a 3 radio dual-band

this guy has a 2.4 radio

and software-defined radio using 5GB

Right now I only have one radio in 5GB

and I’m using all 8x8x8 on it.

If I want to split that into two radios,

I’ll have two radios that are 4×4

Also, this type of AP is “RW Rest of World”

so I can just set up on any regulatory domain

here on the right, the radio info will give me

stats on my 2.4 like how many WLANs I have

Clients, if I have any connected

What channel they’re operating,

channel widths and power levels.

This has been great because we set up some SSIDs

for testing and we manually came and

set up the power levels.

So let’s see how we can go through

and look at all of these settings.

Starting with the monitor tab

here on the left, we have the “System”.

The System is a breakdown

of what we looked on the dashboard

just a little bit about the AP itself.

Looking at the radio, the Radio 1 is in 2.4

It tells me that, yes, it is enabled

channel is set to auto 20 MHz wide

and 10 dBm power.

It also showed me the antenna gain

My second radio is enabled.

The channel is automatic as well.

And I made it 20MHz wide channel.

And I’m transmitting 16dBm.

On the WLAN tab

it gives me information about my SSIDs

I have one in 2.4 that’s my wlan1

my wlan2 is an SSID I created in 5GHz

And this is the summary of the, of that SSID

I also created a third one just for testing.

Looking at the network, it gives me information

about the IP address obtained on my default VLAN

and information on my interfaces.

Also if I were to have some other routing

or Ethernet ports configured

that information will show up in here.

The DHP server I have not enabled on this guy

so it doesn’t show anything

On the Services

It’s a summary I will show you under Configure,

which is our following tab each one of these options.

This remember, the Monitor, is to look at the

configurations on each one of those.

Let’s now look at the Configure part.

If we start with Configure System.

Here is where I would set the name

of the access point

Location and Contact Information

and Country Code.

This is the place where I would choose what

Regulatory Domain this guy will be operating at.

Also, if it’s an indoor and outdoor placement.

And here is the place where you can

split these 5Ghz 8x8x8 into two, 4×4 radios.

So to apply this, I would have to restart the device.

I’m not going to do that.

But here it specifies that it will just split them

one of the radius will be UNII-2c and UNII-3

And the other one will be in UNII-1 and UNII-2a

to prevent them from being too close to each other.

I am going to disable that guy.

Edit this if I want them “on”

under the Management,

here is where I will set up SSH parameters

and what ports I want to use for Management

and radios also SMNP information

and NTP servers will be set up in here.

Another little bit of information.

This video is not to show you how to configure

every little one of the options here.

Just to give you an impression and a little quick

overview of the interface.

Under Radio.

Notice I’m still under Configure

and here I have Radio 1

and the settings under this Basic tab

will affect my 2.4 Radio.

Yes, I have this radio enabled Channel is Automatic.

But notice down here

where it says Candidate Channels,

I specified 1, 6 and 11,

So I let it to automatically assign a channel.

But out of these three, I don’t want it to land

This is to prevent this from landing.

the AP in channel 3 or 5 or 9 or 10.

So I force it into 1, 6, and 11,

The Channel Width I force it to 20MHz wide channel

And I manually specify 10 dBm as my power level.

Beacon Interval that’s default.

And Airtime Fairness I have that disabled,

but here is the place where you would set that up.

Also what fi Mode you want.

You could have “b”, or “bg” or “gn”

or all kinds of combinations,

but I force it to be “n” only.

And with Short Guard Interval enabled.

If I want to do some of channel scanning

here’s what I would enable that.

And also the Auto RF.

Notice that the Auto RF this is the RRM option

it will change to a different channel

based on either Interference

or on Channel-Utilization.

And if you choose by Channel-Utilization

I can set the threshold

and by default it’s set to 25%

So if a channel is 25% utilized or more

then is going to try to move to a different channel

and it will try to hold the channel for 120 minutes.

Also under the 5GHz radio if I click on the 5GHz radio

the options are the same, but for the 5Ghz radio.

Channels it will show me what channels.

Notice that this guy is on UNII-1 and UNII-3

Perhaps it doesn’t have the approval

for using the other channels.

Also, I force the channels to just be 20MHz wide

with a transmit power of 16dBm.

This is the place where you change that

as well as what fi Mode you want to use.

All the rest of the settings are the same for both.

And also there is an Enhanced Roaming here.

This option will disconnect clients

that have too weak of a signal,

kind of like you’re helping them

or influencing them to go to a different channel.

Under the WLAN

I have this SSID in 2.4 only

Let’s look at the basic settings of this guy.

It is enabled. Mesh is off.

Here’s the name of the SSID

You can just call it whatever you want to call it.

And I left it on the default VLAN.

If you have more VLANs created

then you can assign it to a separate one.

Security I have “open”

I have the osen, which is for Passpoint.

I have WPA2 and WPA3 options.

I have it open right now

and notice that I am advertising in 2.4 only

Let’s jump down here to the option for Band Steering

That option is disabled

We don’t let our devices decide

what band to send clients to

We manually set radios SSIDs

on 2.4 radios only

or 5Ghz only radios

also in here I will set up the Client Isolation

Some vendors call these peer to peer communications

or client to client communications

So this is to allow or prevent clients

from talking to each other without going through

the access point.

The option to hide the SSIDs will be here

And also under the Advanced Settings

You can schedule… enable the

Unscheduled Automatic Power Safe Delivery Mode

And very important, this has QBSS load element

This is great because on the Beacon it gets announced

giving a report on how busy a channel is

giving Channel Utilization and also Station Count

It helps clients make decisions on, you know

is this a good AP for me or not?

Here as well I can set the DTIM interval for this SSID

There is some more additional information

and all of the information here

including if it’s going to be Tunnel

If it’s going to be using 802.11k or v or r

then will be under the Basic settings.

Now, all of these settings affect this SSID only

Also, Radius Survey information will be here.

If it’s going to be a Guest Network

then you can Enable it and provide

additional information under this tab

Usage Limit. This will be for rate limiting

And remember, that’s not recommended

But here’s where those are

in case you come into an engagement

that requires you to do so

Also under the WLAN tab

You can also for each SSID

you can configure Access

And you can configure any Passpoint settings

Those settings will be here for that SSID

If I want to create a new SSID

all I have to do is click on Add WLAN

I have three created so far

so my next number will be my WLAN ID 4

and then I create all of the settings

that we just went through

Here’s where I will give the SSID

if I want to add security

on what radios I want to advertise that SSID

and so on and so forth

Let’s move now to the Network tab

The default VLAN is 1.

and my IP settings are said to DHCP

If you want to assign a static IP to this access point

Then here is the place where you

would set that IP and mask

Also, if there are IPv6 settings

that you want to configure

here’s the place to do them

And on the routing and DNS

You can add also additional DNS servers

and any other information

that you need for these device to be accessible

Under the Routes

you can just add more

and Ethernet Ports remember, you have two ports

One is an MGIG port, so there’s a 1, 2 and 5 gig

And I have a 1 gig port as well that you can enable

And for security, there are some DoS protection stuff

like IP Spoof and ICMP Fragment

There are, you know, a little bit of things

you can do for security

DHCP, I have not enabled this device

as a DHCP server, but if you want to have this device

distribute IP addresses, here is where

you would create a new pool

Also for information for Tanavoli, employee information will be set under the network tab.

And also if you want to create multiple VLANs

and assign SSIDs to different VLANs

here is the place

Under Services

If you have an LDAP Server

then here is where you would enter that information

Speed Test. I enabled this

We’re going to look at this

on the troubleshoot section

And also if you want to include an Option 82

here is the place

Now under Operations,

here’s the place where you would do menas like upgrade the firmware this software, reboot

the device or set it back to actual default.

Or if you have multiple apps, you can flash the is to identify which ones those are and

also import and export the configuration for this device under the troubleshoot.

Does the last stop here on the left, you have the Wi-Fi analyzer.

I can select the band if I want to start a scan in two point four, you will get off

channel and go and scan on every channel and see what other networks, SSD and their Mac

addresses are around me.

So this will give me some information along with some noise levels.

So this will help me a little bit in identifying what channels could I use in this area.

I can do the same thing on five gig.

Of course, this is not going to replace Wi-Fi exploded from Adrian Granados or Wi-Fi light

from Helga.

This is just.

Another cool troubleshooting tool that we have in here as part of the interface, also, if

we look at the spectrum analyzer, I tried generating some signals with the Wi-Fi matrix.

This I could not either on safari or on chrome.

I couldn’t have it.

Show me some relevant information.

Again, this is something that is there.

I know there is anything else that I have to do to make it work, but this is not a

replacement for my sidekick.

I’m not going to replace my sidekick with this.

And this is not why I would buy one of these cambium eight by eight by eight access points

to the spectrum.

Know I have the psyche for that on the speed test I tried.

I have a WLAN Pi and setting up the IP address as my end point nine to one, twenty eight

to fifty four does the IP address of my WLAN Pi.

I try to either upload to an uplink or downlink and it just gives me an error.

So if I wanted to really do some testing, I’ll figure out how to make this work.

But that’s not a priority for me on this device.

I do use the ping from here just to make sure I can indeed get to CWNP in my my ping was

successful. The packet capture.

I did some captures and my w LAN on the first one and it’s basic, it captures Packards,

but it’s not I don’t have an option like to export this as a pick up and input into Omni

Peak or Wireshark to analyze.

This is kind of another feature that I have there along with the logs.

Remember, this video is not showing you how to configure just to navigate and show you the

different options you have.

My first impression with this guy is it was really easy to configure and very, very,

extremely easy to navigate.

Also, I created an account in computer networks because they have the computer networks

management in the cloud and it’s free.

So I went created an account very quick.

I received an email confirming that, yes, I wanted to register.

Once I went and created the account, I logged in and here I am.

I have access to the interface design management system that comes to you at no cost.

Kind of surprising as well.

And I can on both devices from here, I can claim device.

I have not claim any device yet, but I could claim and manage the cambium devices from

here. So very easy to use, very intuitive as well.

It provides plenty of information and just a single pane.

If I were to have multiple devices in multiple locations, I could manage them from here at

no extra cost.

Sounds too good to be true, huh?

Well, we’re so used to fees, fees, fees, but this guy seems to not have one.

That is it.

We did do some testing with this device.

We’ll be showing those results in different set of videos.

And this was just to show you the interface, how easy it is to navigate and configure and

set up.

We will see you again in our video.
