Configuring multiple ethernet ports in a switch via bridging?

[DominikHoffmann]

I just came across this video on YouTube. It is about three years old. Contrary to what the video portrays, I thought ports are aggregated into a switch using the Interfaces → Switch → VLANs. This video uses bridging. Which is correct? If both are, which is better?

Steps I transcribed from the video:

1. Interfaces → Interface Assignments. Add new interface for available ports.
2. Select new interface in Interfaces → Interface Assignments and enable it. Save and apply changes.
3. Do the same for other ports, as well.
4. Select Interfaces → Interface Assignments → Bridges. Click on Add for a new bridge.
5. Add member interfaces. Add a description. Save changes.
6. In Interfaces → Interface Assignments select the new bridge from Available networks and click on Add.
7. Click on the name of the new interface to configure it. Enable it. Change the IPv4 configuration to Static IP. Change the IPv4 address to a new subnet. Save and apply changes.
8. Firewall → Rules. Select bridge’s tab. Set up a default rule fro IPv4, Protocol *, Source *, Port *, Destination *, Port *, Gateway *, Queue none. Save and apply changes.
9. Services → DHCP Server. Select bridge’s tab. Enable DHCP and provide DHCP address range. Add DNS servers. Save.
10. Test DHCP by plugging the cable into the physical port added to the switch.
11. Add additional physical ports like in Steps 6–8.
12. Add new interfaces to the bridge like in Step 5.
13. Disable DHCP servers for the original interface.
14. Plug an additional device into any of the new switch ports. Ping from one host to another. Test all combinations.

@dominikhoffmann There is a lot of nonsense on the internet - that video seems like one of those.. No you would not bridge 2 interfaces on the router and plug them into the same switch.. You just created a LOOP..

You can somewhat try to simulate a switch port with 2 interfaces and creating a bridge that you would connect devices into, or 2 dfifferent switches..

But a bridge is not the same as a switch port - if you want/need more ports than use a switch..
