- In this video we're going to take a look at Netgear's GS108Ev3 network switch
Netgear GS108Ev3 8-Port Gigiabit switch
amzn.to/3TUrTJJ
It's an 8 port switch which is part of their Plus Management range
What this means is that if you want to separate your computers, and you should for Smart Home devices in particular, you'll be able to configure VLANs on this switch
Now if you buy an unmanaged switch on the other hand, you'll need to buy additional switches for each network segment
So while managed switches do cost a little bit extra upfront, they can save you money over the longer term
Energy efficient ports is another useful feature for this 1Gb switch, but what is it like to configure and is it worth considering?

Initial Connectivity:
Other than using Netgear's discovery software, there are two options to access the switch and manage it
One is to cable the switch into your existing network and it should obtain an IP address from your DHCP server; You'll then need to find what IP has been assigned
Without DHCP, the switch will use an IP address of 192.168.0.239. So you could connect a computer to this switch and assign it's interface a static IP address of 192.168.0.100/24 for instance
Either way you need to point your web browser to the switch's IP address and you'll see a login prompt
NOTE: The session is not encrypted because it uses HTTP, which is a security let down
There is no username to login with either. Instead the default password is password
When you first login, you'll prompted to change this password, which is a good thing as you should change it
So enter and confirm a new long and complex password then click Change Password
From then on you can manage the switch using the new password
Overall Opinion:
Because the switch is managed and supports 802.1Q VLANs this is certainly a network switch to consider
The security could have done with more attention though
But configuring this switch is relatively straightforward and it does offer a lot of flexibility
So it would be something suitable for a small office or home user as an entry level switch

Netgear GS108Ev3 Review and Setup - Наука та технологія
Thank you so much for the comprehensive video on this managed switch. I'm just now starting to get into managed switches.
It's a useful switch, good to know the video was helpful
David, thank you so much for this tutorial. It was and is really helpful. I am new to Networking Switches and this been a low-budget switch and your explanation took me to a whole different level of understanding so quick. Thanks again!.
Good to know the video was helpful
Thanks for the feedback
Wow! Thank you for this video, It helps a lot, cheers from Spain!!
Good to know the video was useful
man you got the knowledge sharing skill.
Thanks for taking the time to comment
Good to know the video was helpful
Rate limiting is also extremely good EXTREMELY GOOD for gaming
Yeah, that's a good point
The GS308T switch does allow management over HTTPS, in addition to many other features. I have a GS308T at the core and GS308E and two GS305E at the edge. I eliminated all unmanaged switches about 18 months ago when I upgraded to Gigabit for the NAS which I installed then.
One annoying thing about Natgear is that different ranges of switches are actually made by different people, and have significantly different management interfaces. There are also minor differences between your switch and mine of the same model; probably different firmware versions.
I don't buy that many switches to have noticed
I found differences between this last one and one I already own but I wasn't aware the management interface was by different developers
@@TechTutorialsDavidMcKone Not just the management interfaces, The switches themselves are made for Netgear by different companies. The status lights on each port function quite differently on different models for example.
nice tutorial i have also a 1gig internet i hope this switch wil propperly work with iptv watching once i setup when i got it.
Thanks for the feedback as it's good to know if a video was helpful or needs improvement
I bought it yesterday to shape the traffic in my house together with Opnsense for splitting IoT devices from home computers. Your video helped me a lot however I am still far from understanding it all ;-) Time will tell if I am able to do what I want to do ;-)
It makes a lot of sense to separate your IoT devices and OPNsense is a good choice
I do prefer the layout of pfSense for rules but the community edition just doesn't get much attention these days and hasn't had an update for a long long time
Anyway, good to know the video was helpful
@@TechTutorialsDavidMcKone oh yes man! I am going through all your videos - so helpful. ;-) Good job for the community
Nice thorough review of the switch. A couple of questions though.
In the vlan section (for simplicity lets say you have only 2 vlans, vlan1 and vlan2) the vlan1 would have a network segment of 192.168.1.0/24. This would have been taken from the router's settings. Now that there is also a different vlan (vlan2), would it still be assigned with 192.168.1.0/24 ip addresses (and if yes, then the devices on those vlan2 ports wouldn t be able to communicate with devices on vlan1 because of the physical port separation on which they are connected to even though they belong to the same network segment) or you have to set it to a different segment at the router's side?
Normally when you create VLANs each one has different IP addressing; 192.168.1.0/24, 192.168.2.0/24 for instance
ISP/retail router's aren't usually that clever and won't cope with VLANs
But it's better anyway to use a firewall that can handle VLANs and configure it with interfaces in each VLAN
This way the computers in the differenet network segments can only talk to each other if the firewall will allow it
Thanks for the video. I have a USB-C dock with power passthrough that creates a broadcast storm when the hub is disconnected from the computer while the Ethernet cable is still connected to the dock. What would you suggest is a good broadcast filtering setting to block the broadcast storm on that port while not affecting normal traffic?
There is no one setting as it depends on the network
But Cisco for instance suggests a threshold of 10% of the port bandwidth, so for 1Gb/s that would 100Mb/s
If that starts causing problems for computers increase it
On the other hand if it isn't having any real effect decrease it
Thanks for the review. Wondering if this switch supports inter-vlan routing, thanks 😀
Unfortunately not. They're just a Layer 2 switch
Thanks for wonderful video. I am facing a problem that when I am creating basic port based VLAN and creating say another VLAN no. 2. The hosts in that VLAN are not able to connect to internet. My Switch is connected to a wifi Asus router in Port no. 1. How to enable internet access to other VLANs ? Does the port where internet access router is coming should be assigned as ALL ?
The other VLANs need to be serviced by a router or firewall in the other VLAN
Computers on a network need a default gateway in the same VLAN to reach the Internet
That device will then forward the traffic for them
If your Asus router supports VLANs then it could be configured to do that but the switch port will need to be converted into a trunk port for this to work
If it doesn't, but it has multiple physical interfaces then one interface could be placed in this other VLAN to service those computers
Otherwise you need another device that either supports VLANs on a single interface or has multiple physical interfaces
Very helpful! Thanks. Wonder if you can help with a question - Any idea why my hard wired windows computer connection to this switch shows that it is connected at 1000mbps in the management software but, after a few days, the internet speed tests results slow right down from about 500mbps (I have fibre connection at 1gig) to about 100mbps? A reboot of the switch sorts this for a while but it then slows again later. Using Cat 5e cable, about 15m in length. Had this problem with a previous non managed switch so its not the switch itself.
I assume the same switch connects to an ISP router?
Because a direct connection to the Internet would be unsecured
When the problem occurs does the router show a lot of traffic on the link at the time?
If so I would try and check to see what that traffic is
Otherwise it could be a hardware or driver problem that is manifesting
There could be an issue with the router or its cable and a link reset is temporarily fixing it
Have you tried testing another cable for the PC?
Or even another computer?
Because it's also quite possible that there's some software on the PC which is downloading something for instance
And that reboot is forcing it to restart, which could gradually build up traffic load
@@TechTutorialsDavidMcKone Thanks - so no simple answer then! I will have to do more testing as there is a lot of stuff on the network (Mesh network which also runs the DHCP, smart home hubs etc). I don't think there is anything using much traffic. Speed to the Mesh (from the ISP router) is perfect (about 900meg whenever it is tested). So it is internal, I have setup QOS to give my PC priority etc too and changed the patch leads. I have suspicions over the cabling to my computer but it is built into the home and I am a long way from the switch to connect directly for a week or two without risking garrotting someone! Anyway, will work it out one day. Thanks for answering.
Mine was doing exactly the same thing so I enabled flow control on all the ports and now its back to near gigabit.
Thank you
Thanks for taking the time to leave a comment
And good to know the video was helpful
@@TechTutorialsDavidMcKone very helpful, sharing knowledge is mark of good people
We can modify/ change the native vlan on cisco smart switch such as cisco sg250 or CBS350.
There is a cisco video tutorial named "Cisco Tech Talk: Changing Default Native VLAN on a CBS350 Switch"
Can we change it on netgear switch? I cannot find where the native vlan is on Netgear switch....?
I can only find the management vlan on Netgear switch, is this the same as the native vlan on cisco?
For switches like these Netgear ones, you have what's known as a primary VLAN ID (PVID)
By default it's set to VLAN 1 and you have to change it for each individual interface
There is no global setting that I'm aware of
On a trunk port you set this to be the native VLAN
On an access port it will be the access VLAN
thank youfor the video. Im very new in networks, how to you recommend me to config my smart switch netgear GS305e, its 5 ports and i need to config 4 ports and one be able communicate whit oder ports like a NAS.
Unfortunately I don't provide personal training or individual support
But what I would recommend is taking a look at one of my other videos
ua-cam.com/video/DAidgB9Vu1s/v-deo.html
In that I go over configuring a similar Netgear swtich
If you then come back to this video at about 12:16, I go over how VLANs are handled for this particular model
Many thanks for the suggestion, have a great day.
Well, I came across a problem while configuring TP-Link SG108E where even when I removed a port from VLAN1, the IP address of that switch was still reachable on that port. It applied even to TRUNK port....i followed your instructions in the video. So, I'm wondering whether you tried testing the Netgear switch that after you removed the ports from VLAN1, the IP address of the switch was not available on that port. Maybe the Netgear switch has similar bug in the firmware.
Unfortunately this Netgear switch doesn't provide an option to change the management VLAN. It's stuck on VLAN 1 so that's what I'll access it on
But I know on some models it isn't possible to remove VLAN 1 from a port, even if you want to
As far as I recall Cisco switches allow you to remove VLAN 1 from a trunk but it actually remains active because their switches communicate with each other using VLAN 1 regardless
So it's possible that's what you're experiencing
@@TechTutorialsDavidMcKone Thank you for your prompt response. I just wanted to configure the switch in a way that some of the ports would face WAN part of the network and I wanted to prevent end devices connected to these WAN ports from being able to connect to the switch IP address....for security reasons. I was considering buying Netgear since I thought it would have better firmware, but it seems most of the switches in this category will have the same issue with this. Anyway, thank you very much for your videos, they are always very helpful and comprehensible.
Thanks for the review. Wondering if this switch supports inter-vlan routing, thanks.
Unfortunately not. They're just a Layer 2 switch
@@TechTutorialsDavidMcKone thank you.
Netgear do sell layer 3 switches, but they all seem to be larger rack mount units. I would like to see a 8 port one.
The switch shown here has only limited management capabilities. Netware sell a more sophisticated 8 port switch, the GS308T, which can do just about anything that you would expect of a layer 2 switch. Still waiting for a layer 3 version though.
A lot depends on what you want out of a switch and in most cases its just VLANs and port security
A layer 3 switch is useful for large organisations that have lots of users with the same needs and routing between their subnets is acceptable
Otherwise a firewall makes more sense for security reasons
I bought this switch to install in my home entertainment system. All I can say is WOW! This is the same switch the high end audio manufacturers use in their $500+ "audiophile" network switches.
Where it made a huge and evident impact was with my Sony 55X800E television and inexpensive Polk S1 sound bar with bass module. The PQ on the Sony was brighter, sharper, colors and blacks immediately improved. Then the sound bar, all of that digital harshness was gone. Not that there was a lot, but it was there, to the point my 80 yo mother asked what I did to the sound.
The sound now has a class A/B amplifier sound to it, very smooth delivery. There was a rough, or harshness to the sound, that is all gone. And then the bass module, we now have nice deep bass. Will it compete with my two SVS SB3000 subs? Of course not. The bass is 100% better, as it now fills the room, where before it was barely noticeable.
I paid $39 on Amazon for this switch, it is $42 today. I ran CAT6 from the router to a TP-Link ER605 V2 Wired Gigabit VPN Router, then a CAT 6 patch cable to the NG 108. CAT 8 to the Roku Ultra box, the BuzzTV Android box and Pi2 Mercury V2 streamer HDMI out to the TV through an inexpensive UGreen HDMI switch. None of the cables I used were expensive, around a few bucks each, none over $10. I probably have around $150 invested in all of this, it was worth every penny.
Out of curiosity were you using WiFi connectivity before?
@@TechTutorialsDavidMcKone No, hard wired. The sound improvement was very profound in my setup. I was using a basic 8 port TP-Link switch, the TL-SG108E prior to the NG.
I am super surprised that digital part of your audio has such impact on the analogue one. Unless you have really huge lags in your network (in which case managed switch helped you)
@@zyghom Surprised the hell out of me too! The network is solid, I actually have two isp's at this location and have used both without issue, and the same results with this switch, noticeable SQ and PQ improvements. If it had done nothing, or just a slight improvement that could be said is "in my head", I would not have even bothered posting any of this. The switch does clean up the connection, when an 80 yo great grandmother asks what you did, you know something is going on. And yes, she was in the house when I added the switch, and I said nothing about doing that, there was no prodding her on my end. The change was that dramatic, especially in regards to the audio, that was the first thing she commented on.
@@michaelwright1602 man, 80 yo grandma ears are amazing then! I - being quite younger- realised my higher kHz are getting lost ;-)
Anyway: 100 years to her and congrats to you for getting better SQ
This is old, but i can't access the switch using the web browser.
It says connection refuse.. Has anybody encounter anything like that? And does anybody has a fix
There can be many reasons for this, so it's difficult to say
Make sure the computer is in the same network to avoid a firewall blocking access
Try a different browser as some browsers can be a problem
Try a different computer, even a phone in case anti-virus software is blocking access
@@TechTutorialsDavidMcKone thanks for the answer. I try with the phone wi fi, i can access the router using the browser. But the changes doesn't take effect.
Is weird..
Also try different browsers and didn't help either
I want to manage a switch but he don't accès but put 192.168.0.239
The switch may have another IP address
If it was plugged into an ISP router for instance you'll need to check the router to see what IP it was given through DHCP
If it's not plugged into anything, then it should be accessible on 192.168.0.239 as shown
But the PC needs a static IP address in the same subnet e.g. IP address 192.168.0.100 Subnet Mask 255.255.255.0
