Re: Seeking LAN Setup advices

No.

Vlan tags are used for shared physical media between switches/routers which
are vlan tag aware. End points can also be vlan aware (i.e a linux box).

Normally you will tag a physical port of a switch to be a particular vlan
and then attach your other crap off it.

In the scanario described you are simply putting two vlan tags from the
cisco along a common pipe then telling the wifi/connecting switch to treat
each tagged frame different (for example having two 192.168.1.0/24 wireless
networks which dont interact).
