Hey Ali, thanks for this! I have a question regarding the double-tagging atttack. If I understand correctly, what you describe is that the switch will strip the VLAN tag from inbound traffic on a native enabled port - "correcting" tagged traffic to native traffic. Is this common among all switch vendors? I have not experienced this myself. Sending tagged traffic on a native port results in 100% loss for me. I assume that could be a setting on the switch (HPE Aruba). Also, any thoughts on how to avoid native VLANs without breaking a leg? I find most windows clients require some TLC to start talking in tagged traffic. For larger enviroments that's a lot of fidgeting around with drivers, network cards, etc. If you have any pointers in that regard I'd be intrigued to hear them.
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.
@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!

@@James_Knott Yeah, there is something cisco like called VTP...
@@fps_purple9556 Yeah, that was Cisco's proprietary VLAN. However, everyone supports 802.1Q.
