why do you set the trunk port to 24? is that the port that is connected to your router?
Yes, I usually set the last port on switches to be the connection to the router, just for ease of identification and continuity on my sites. The router is going to be sending VLAN tags down the link to the switch. If the switchport is set to an access port, then the switch would disregard the tags coming from the router as it doesn't know what the tags mean. When you set it to a trunk port, you're telling the switch to understand the tag values and direct traffic either to a access port, or continue down a trunk to another switch, or access point.
@ thanks for the quick reply. I’m trying to set up an IoT vlan to help keep things more secure but I also don’t want to lose connectivity to access certain devices across the vlans.
These videos are so unbelievably helpful. Thanks a bunch.
Clearly explained😊.
thank you for this amazing explanation and the good animation in the video
Can we say 802.1x is considered as identity authentication module ??
Those switches are unnecessary. You can limit Mac addresses without it. Thumbs down
You certainly can! Thank you for commenting
What's the modem setup to go along with this wifi system to get these results?
And... How would you expose a service if needed? At some point you need to open a port if you need exposing a service, whether that's SSH directly or not. The advice isn't "do not open ports", but in this case, use a pubkey authentication... And a firewall. The first thing done in some sshd installation is actually disabling password authentication.
Absolutely. That’s why I say this is just a problem with opening ports unnecessarily. It was mainly advice for someone I spoke with who opened many ports to the public internet. Just trying to keep it simple with out going to in-depth into authentication methods in a 1 minute video.
I suppose a example I could mention is many CCTV installers I have seen in the past, still open ports to get to WebUI’s of cameras or NVRs. Using the manufactures own app’s or a VPN would probably be a better option.
Awesome
Very helpful. Thank you Sam.
Please explain how the variability works, it looks like you just created 4 fixed length subnets. You are also now using 4x Network IDs, 4x Gateway IPs and 4x Broadcast IPs within a 255 address space. Additionally if you need to add a new device and run out of IP addresses you will need to re-IP an entire network subnet. Any devices that are statically assigned will need to be changed.
If it was FLSM, each subnetwork within the 0-255 network space would have the same amount of IP Addresses. A 255 255 255 192 or /26 per subnet would be; 192 168 1 0 to 63 - 62 host addresses - subnet 1 192 168 1 64 to 127 - 62 host addresses - subnet 2 192.168 1 128 to 191 - 62 host addresses - subnet 3 192 168 1 192 to 255 - 62 host addresses - subnet 4 If you planned a network with 20 hosts, then 62 addresses is overkill for that subnet, so you make the subnet range smaller within that bigger subnet, thus varying the amount of IP Addresses within the bigger space. In a real-world scenario, you would need to plan the subnets based on your specific requirements and the number of hosts in each subnet
@@SammytheSalmon That's a fair reply, It just seems that in the example provided you use private IP addresses which in most deployments shouldn't be necessary to subnet to that degree (altho nothing stopping you from doing so). While for Public IP addresses its more common to see variable-length subnetting. I would like to see another video on supernetting.
@@DarnCombYes, i completely agree, VLSM is seen more in Public IP Addressing. Here is a video on Subnet and Supernet, I will work on a dedicated video - ua-cam.com/video/CUM62WSMvmg/v-deo.html
I believe you have set illegal Gateway IP Addresses in the video, which I found slightly confusing or did I understand something wrong?
The Gateway IP address is the first usable host address in the range. The 'Start IP Address' is the start of the DHCP address range. I have just confirmed it with a subnet calculator and it all checks out.
I know Bradford when I hear it 💯
Great video - allot of essential info carefully delivered in a clear manner - thanks 👌
That was a very nice video. thank you!
Fantastic videos Sammy very informative 10/10 from me. Listening to your language makes me think you're involved with networks and business for an ISP. Well done dude.
On windows 11 laptops we are unable to connect to wifi. We have ruckus AP and DC as a NPS. Certificate window is shown, which tells, it does not like a certificate. In certificate our DC name is shown with Capital Letters, like SERVERDC.domain.xx. Could you please assist, how to fix this problem? At the same time windows 10 laptops can easily connect to same wifi SSID without problems. We use EAP with activated checkboxes for CHAP and CHAPv2.
Very good video .. Well made and explained ..., I liked particularly the practical demonstrations.., of course routers are different..., but the video gave me an opportunity to see what to look out for... Thanks..
1. Need to create VLAN in router 2.Need to create trunk port for communication between router and switch 3.Need to create trunk port for communication between switch and router 4.Need to create for each VLANS some ports in the switch (where we can connect access points, pc etc) Is that true or I am mistaken? Thank you!
can managed switch work without router? As I understood managed switch don't have dhcp serve? Thank you!
Outstanding content, thank you 🙏
This is a great video, you need more views!
At my last job (before I knew any of this) someone was sent to a site to fix a loop back issue at midnight. Sadly no one knew how to find it until I found a command to show MAC address table. We spent all night figuring out the layout… I did not get a raise lol.
I like your intro sequence - I think I’ll call it RIP headphones users
Great video, well explained 👍🏼
Oh yes Sam, sharing videos, pictures and ringtone via IR on my Siemens SL55 😎
The good ol' days!!
Foo Fighter passwords! Nice!!!
Very good video.
very very informative video, thanks!
of all the videos I've looked up, this has been the one that lays it out best quite frankly, thanks!
Great video Sam! #Connect44Life 😅😂
1:40 got me. I work in school IT support. At one of my sites, whoever wired and labeled a wing of classrooms, did a terrible job in labeling. I had to help a teacher with some network connectivity problems. I decided it was best to have her laptop hardwired to the network. However, the ports weren't patched in. no problem I though. I'll just patch them into the switch at the cabinet. I quickly realized that all of the ports in that room were just labeled "Room 2" both on the patch panel and data drop. It was insane. I didn't have a tone generator on me at the time so I had to figure it out one at a time.
I’m a network engineer and I wanted to commend you on the level of detail and accuracy in this video. It was well presented and to the point and was enjoyable to watch. Thanks for producing this content. Cheers 😊
To Sammy, I am normally very critical of YTflogs who puit up videos spewing tripe but here in the very first video I have seen of yours, I am hooked. Your terms and explanation is superb and very refreshing.
Great content,thank you 👍🏽👍🏽
dude when tom and jerry popped in the get on my network i was like subscribe hahaha. Very nicely done as far as editing and teaching
Great video mate. Appreciated
The way you've presented the information is excellent! This is an awesome video, thank you.
802.1x user authentication fails when an RDS connection established on windows users, can you help?
Amazing video and great quality! Thanks!
Great video. Comment for the algorithm.
You're bad ass and you know your stuff dude! thank you for the content.
Many thanks for the support!
Excellent that Sam 👌🏻
Cheers mate!
Microsoft's Active Directory can be used for 802.1x authentication.
amazing video, there aren't many videos about this topic but this one is an outstanding one. Keep it going!
Thank you for the feedback! Much appreciated
Bro, you're mad knowledgable! Props and hope more videos come.
I appreciate the feedback! Thank you
is it possible to use a router with link aggregation to feed 2 ethernets into a 24 port switch to help handle bandwidth on a home network?
Some routers support LAG, you will have to check their spec's. I think some Cisco router support LAG.
I like how you included the media converter part about an active link.
Fantastic video definatly a pretty cool watch
Thank you very much
could this be used on a cable modem to increase speeds past 1gbps?
This method doesn’t Increase speed, but throughout. You won’t get 2Gb throughout, it is 2x 1Gb connections.
