GS108E challenges

a) Create new VLAN 'IoT', tag 10.

b) Set port 6 (the laptop) to this VLAN.

Now I can't even ping the switch!

$ ping 192.168.1.3

I... what? Surely setting a VLAN wouldn't lock me out from the management page?

On  the OPNsense adapter intended for the trunk, all the (four?) VLAN are [T]agged - or is there one VLAN [U]ntagged? In my experience, and here in the community, the majority of such issues are caused by the big, powerful firewall applinaces.

Scratch the Basic Dot1q approach - like this you can either define a port as Access Port [U]ntagged and the matching PVID, or as a Trunk Port (all [T]agged). 

I'd suggest to use the advanced VLAN config instead. Properly configure access port #6 for the VLAN 10 as [U] and the PVID is set correct to 10 for the port #6? And on the port for the trunk, you can use one VID [U]ntagged with the appropriate same PVID.

2) 'Communication Error.'
So, then I tried the Advanced VLAN. My steps were :

a) Click 'SWITCHING' -> 'VLAN' -> 'Advanced 802.1Q VLAN' -> 'ACTIVATE MODE', and continue past warning.

b) Click 'APPLY'.

I get a modal 'Advanced 802.1Q VLAN Communication Error.'. Other than a few CSS or JavaScript warnings and errors (all presentational as far as I can tell), there's nothing in the console.

How do I resolve this error? It crops up whenever I click the Apply button, regardless of what config changes I've made.

Factory default the GS108E, and restart from scratch, enabling the Advanced mode, ...

Have deployed the current GS308E v1.00.11 firmware?

Using some "exotic" browser, or an industry standard Chrome or Firefox?
