At this moment in my company i have two gigabit switches (zyxel dimension gs1116) and one 24 port 100M linksys switch . None of them is managed. In server room are 2 switches. One gigabit switch and linksys. Second gigabit switch is located on buildings 4th floor. Also somewhere is basic 8 port edimax switches (2 or 3).
Now we bought
HP V1910-48G witch is 48 port gigabit switch. Now i remove two switches in server room and place HP there. New switch is placed, because we need to separate public wifi from company's network. And also move cash registers into separate network.
I created two VLANs. VLAN with id 2 is company network and vlan with id 3 is for guest wireless access.
VLAN 2 and 3 have assigned port range from 1 to 32. Booth VLANs port membership is tagged.
And question is: if i connect all cables to new switch, all stuff works? Or i can get in trouble.
Of course i will replace switches after working hours and test connectivity. I am asking, because to be know if i need made some changes to router too. And does basic switches can handle VLANs ? Or they don't care that?
Firewall: Firewall is basic computer running
iptables (shorewall). I know that i must reconfigure firewall, to forward wifi guest packets to gateway interface only.
VLAN with id 1 (default) i leave unchanged (all ports is assigned as untagged).
I imagined second scenario: company network uses untagged ports and only mark public wifi traffic?
Public wifi is planned to mark via separate SSID
