We are connecting three offices via fiber optics. For each office we have one switch. In each office there will be one PC which has to be isolated in a VLAN A. There will be other PCs but those three have to be in this VLAN A.
Each PC is connected to port 1 on a switch, through switch management on each switch we say on port 1 there is a VLAN A. Switches are not stackable. Will those three PCs see each other, or do we need to do something else? Will they be isolated from other traffic?
