VLAN Query

Archived from groups: comp.dcom.lans.ethernet (More info?)

We have two physically separate networks (one say, 172.16.0.0/16 and the
other 192.168.0.0/24) in one building, that we wish to make available to
clients in a separate building, linked via a single CAT 5 cable.

Is it possible to use VLAN's (and associated compatible switches) to allow
traffic from both networks to traverse the single cable to the other
building?

Hi Walter,

The switches that I will be using are two Netgear GSM7223's
(http://www.netgear.com/products/details/GSM7224.php). They will be
connected to the 192.168.0.0/24 network fibre backbone connected via the
gbic slots. I'm planning on using ports 1 and 2 on the switches for the
172.16.0.0/16 network, while the rest would be used for the 192.168.0.0/24
network.

So far I have configured the basics of the switch, and have found the VLAN
setup menu under the GUI. This is the point at which I become a little
confused. I think what I need to do, is to:
1. On the default VLAN exclude ports 1 & 2 - do I need to turn tagging on or
off?
2. Create a new VLAN including ports 1 & 2, but excluding the rest of the
ports - again, do I need to turn tagging on or off?

Am I on the right track? If so, is there anything else do I need to do?

Your help is MOST appreciated )

You want tagging to be off on any port which is not acting as
a trunk.

If you are given an option of "Untag PVID only" or similar
words [ran into this one on a Nortel switch last night] then
use that on your connections that will act as trunks. If you
are only offered the choice of "Tagged" versus "Untagged"
then you want the "Tagged" choice for trunks.
