Shouldn't the EtherType be after the VLAN tag in the tagged frame, as per the standard?

@gauravpatel2005 3 years ago

oh boi... this is mind boggling ... I am not good with networking but this seems pretty advanced. I wonder if this is relavant for SAA course... i am planning to come back to this one again...watched multiple times but i guess my brain firewall is not accepting inbound connections ;)

Will you come out with a aws security specialty course anytime soon?

07:42 , Shouldn't that be called 802.1AD instead of 802.1Q?

Hey , is there a video which is supposed to go prior to this in the playlist? It seems to reference previous material.

Hey adrian.. The way you teach any networking topics is amazing.. Do you have any plan to launch a full networking course.. will be a great help to students like me and also who want to change their domain to cloud 🙏🙏

10:54 this is incorrect. Access ports do not tag vlans. When the frame "exits the access port" no tagging occurs, the vlan ID membership is simply retained. Vlan tagging only occurs at trunk links where the dot1q header is added an/or removed. Access ports simply associate the data with vlan ID membership.
