When your organization wants to divide a LAN into separate virtual LANs (VLANs) to keep traffic and policies for different departments separate, you can logically group Layer 2 hosts into VLANs and thus divide a Layer 2 network segment into broadcast domains. For example, you can create VLANs for the Finance and Engineering departments. To do so, Configure a Layer 2 Interface, Subinterface, and VLAN.
The firewall acts as a switch to forward a frame with an Ethernet header containing a VLAN ID, and the destination interface must have a subinterface with that VLAN ID in order to receive that frame and forward it to the host. You configure a Layer 2 interface on the firewall and configure one or more logical subinterfaces for the interface, each with a VLAN tag (ID).

Nice video. The only thing I would suggest when teaching students/viewers is to show them the "switchport trunk encapsulation dot1q" command first prior to changing the port over to "mode trunk". This is why your "show int trunk" command had no output. Good job though.
