Yes or it can be an uplink to a router. In either case the uplink carries traffic for multiple VLANs. The router can be configured to route the traffic between VLANs and apply firewall rules to permit/deny certain traffic between VLANs.

@@luckbeforeleap Thank you for clarifying

@@luckbeforeleap Maybe you can answer my doubt: is it mandatory to have both a router and a switch that can handle vlans? If I have a "dumb" router, that doesn't support vlans, can I buy a switch that supports vlans and then connect all my equipment to the switch and the switch to the router? Is that possible? Thanks!

@@RaduRadonys You could - but if you want to support multiple networks your router will need to have multiple physical ports. In that case you could connect a switch port to a router port and make sure that they are both handling traffic for the same network. However, having a VLAN-aware router would allow you to carry traffic for multiple isolated networks across a single physical link between the router and the switch.

@@luckbeforeleap Thank you! So in this case if my router has 4 LAN ports and my switch which supports vlans has 8 LAN ports, I can have a total of 4 VLANS? Did I understand correctly?

There is always another way to understand something. You may find other youtubers who may explain it easier. Try them out.

Thank you for the correction

As far as my knowledge goes, people are still on Windows server 2019 and the 2022 version is not so used yet! And as for doing it in real life, I don't have enough resources to perform such task. But I can do it in Virtual machine. I have plans on making videos about Active directory.

Great to hear!

Thank you for your comment! If you mean "Port aggregation" I explained it in this video. ==> th-cam.com/video/0djhTnLZ1dE/w-d-xo.html

A switch port will not accept a VLAN unless it's configured to. So, it could receive the tagged frames and then strip the tag before passing the frame on. Routers can also remove the tag from one VLAN and replace it with one from another. Don't worry about avoiding native LANs in most situations. Much of this video is nonsense.

@@James_Knott Yeah, there is something cisco like called VTP...

@@fps_purple9556 Yeah, that was Cisco's proprietary VLAN. However, everyone supports 802.1Q.

@ronaldratzlaff6672 Thank you for commenting! I suggest you asking that from someone who has more knowledge in this. I am just a simple learner who's trying to improve by teaching everything I understood from my courses.

Hey, that's really awesome! As you probably know well, the teacher learns the most. Don't be afraid to make mistakes. That's how learning works! Keep them videos coming! If you you invite discussion or correction in the video, people might be more kind in their feedback. Just a thought. But keep up the learning and teaching!

Thank you very much, hope you liked it!

Thank you very much for your words. God willing, the videos will improve soon

Thanks for sharing!

I have specified them with different colours and also earlier I said which LANs are similar. In the future as God wills I will improve the videos. Thank you.

VLAN tags are placed immediately after the source mac address before the type field. Please update your example.

Thank you very much @@raypino6695 . videos will improve in the future.

Thanks 🙂

Glad you liked it!

Glad it helped

Thank you for your comments! yeah cmd is bit old and may not be the same with PowerShell, the Unix cmd is a Unix based terminal which I haven't gone through it thoroughly yet; I also have a video on Linux terminal, you can check that one too. Hopefully in the future I may go though it thoroughly. for now I just focus on things I learn everyday; which are the CompTIA objectives. Thank you for your suggestion!
