I see it now in the TOH. I also filtered on "Supported current rel=18.06.2" which this device not (yet) supports. That's why I didn't see and considered it.
What do you consider "standard VLAN" functionality?
Nothing changed to the VLAN configuration after a total reset.
It's not devices supporting releases, but releases supporting devices. And since release 18.06.2 is already, erm, released, it will not ever support this device.
