Rendra,

To some top=posting is a sin and you might be in danger of eternal  
hell fire and losing your immortal soul if you continue doing it. So,  
what you will want to do is post below any replies and trim out  
everything that does not pertain to your next question in the thread.

So, on to your questions.

Question 1: Yes, get yourself a couple of new switches that support  
VLAN. Let your boss know that he will need to pony up and buy new  
switches to achieve what he wants. Otherwise all the traffic will be  
able to be sniffed and you will have no real security, just packets  
with vlan tags that dont do anything. This is a perfect time for you  
to get these switches and be able to expand your networking knowledge  
by being able to play with better hardware at no expense to you. :)

Question 2: That would work. When you connect both switches together  
you will create what is known as a trunk. All that is is a link that  
can pass all VLAN traffic between the switches.

Question 3: Well yes but why? For under 400 dollars US you can have  
two new switches that support VLANs. Don't let this opportunity pass  
you by. If you do, invariably what will happen is, you will in about  
2-3 months down the road want to do something that will require the  
other switch to support VLANs.

It is easer to have them pay for what you need now then to try and  
nickel and dime them later.
