Recently I've flashed stable OpenWrt version 21.02 on ZyXEL GS1900-8HP v2. With a few struggles I've managed to to that successfully. Unfortunately, I couldn't ssh into it at first. After searching forums for solution I've found that I need to setup my network card on my laptop to tag packets with VLAN 100 and connect to port 1 on the switch via ethernet cable. After that, everything worked smoothly. I could ssh into my switch as well as browse Web GUI. My question is how do I set my switch to behave as regular flashed OpenWrt device (plug & play into my router or other switches and grab IP automatically) without tagging ports and also I've found missing 'Switch' section on Web GUI for GS1900-8HP v2.
Any help is appreciated.
Edit: Included network config, changed title name and correct typo, add screenshots for comparison.
