Switch with Port VLAN??

[John Prophet]

I dont fully understand the VLAN concept.... but here is a scenario that I would like to be able to answer.

I know a church that has lots of offices...pretty big church, spread out..rooms here, rooms way over there etc.

They have a school there also and the kids have a "comp lab" with a bunch of comps. The comps are hooked to cable internet VIA a netgear 4 port router and a big hub.

The rest of the systems all over the church are on dial up.

So here is what I wanted to do.

Set them up so that they are all using cable from the router...but have it where the kids can in no way mess with the rest of the comps...cuz I am sure some of the kids are the , uhh, "inquisitive" type.

So the kids comp would need to be on one subnet seperated from the rest of the comps.


So if I had a switch like this http://www.etw.com/ProductInfo.asp?v...oduct=12906769

could I set up a network as I described?

Could I come from the router to the vlan switch...then from a "seperated vlan" port, go to a hub for all the kids comps....then simply use the rest of the switch ports to go to all the various other adults comps?

And what is "port trunking"? Sounds like I could use several ports on one vlan and other ports for other vlans.

Any ideas about it?

Thanks, JP

"could I set up a network as I described?" = almost, but no

By creating two VLANs you could seperate the groups of computers. But as soon as you connect the Netgear router's LAN ports to both VLANs, you've connected the two VLANs together.

To keep the two networks seperate, you will need a second router/firewall.

Port trunking: connecting multiple ports betwen two switches to allow faster data transfer between them

The way I understand it is that I come of ONE of the routers ports into the Port 1 of the switch ..which is a "common" port for the vlans....then, the way this particular switch works is that EACH port of the switch is a seperate vlan......so there's no way that the ONE common port going to a router would make the vlans equalt to one lan..otherwise the "vlan" aspect of the switch wouldnt work.

But yes I see your point...if one were to come from 2 ports of the ROUTERS switch..one port to each seperate vlan..of course the routers switch would make them into one big lan again, lol.
