I am trying to configure the T1600G-28TS VLAN so that I can have the default VLAN ID 1 & Guest VLAN ID 101.  I have succesfully done a VLAN for my alarm system but it is a single VLAN ID100 connected to port 15 with no issues.  My probelm is trying to get 2 VLANs 1&101 to work on the same port 11.

What am I going wrong here?  I would have expected that if I created a VLAN in this case ID101 it would show in port config.  When I change the port config on port 11 to ID 101 the guest vlan still does not work.  What happens is he Unifi default SSID on ID 1 will now make devices connect to vlan101.

My question is can this switch actually do 2 vlans on a physical single port?
