Working behaviour of Fortigate Vlan tagging and untaging

Dear All.

 

I want to understand deep understanding of vlan tagging and untagging with debug.

 

Can anyone suggest article or documents accordingly.

 

thank you.

What exactly do you mean?  Are you asking how VLAN tags work?  How to see them in debugs or PCAPs?

Hi Umesh

802.1q is a standard, so you can start from Wiki page.

https://en.wikipedia.org/wiki/IEEE_802.1Q

 

Then for FortiGate you can start here:

https://docs.fortinet.com/document/fortigate/6.2.15/cookbook/402940/vlans

 

An finally here is a tech tip to create VLAN interface:
