This switch is unmanaged, i.e. you cannot configure your own VLANs, etc. here.

How do you come up with that? The switch is managed and supports VLANs, tagged and untagged!

I bought one here a week ago ...it will NEVER be installed in my network.

Default VLAN = VLAN1 (CANNOT BE CHANGED)
Switch-management VLAN = VLAN1 (CANNOT BE CHANGED)

Lots of VLAN attacks target either the default-VLAN (every managed switch has one) or VLAN1 (most managed-switches have one) ...what a super-stupid place to stick switch-management.

Waiting now for a Cisco ordered here today (switch-management can be any VLAN, default can be any VLAN, management is not forced to be on default)
