TS-473 - Container Bridge Mode not offering any if, after switch change

[gklank]

Hi,

I moved to a new switch Zyxel GS1920v2 because of the increase of required ports.

I kept the config of the switch on the system defaults, just powered on, plugged all stuff in.

As soon as I am connecting more than one interface from the QNAP to the switch, the selection of interfaces / virtual switches shows no entry any more.
Keeping only one interface connected, I can select on of the 4 adapters / virtual switches.

Of course it shows very sure to an switch config issue, but which one?
Which feature of the Zyxel switch is avoiding additional IPs on one adapter?

Any help/tip would be appreciated.


Regards

Gerhard
