Scott,

 

It's going to be hard to tell you the correct information without knowing
how your network is setup.  I believe you will want to setup 2 vlans.  One
for the old subnet and one for the new subnet.  Then, if you want the
subnets to talk to each other setup a route between the two vlans.  You do
not need a third vlan.  

 

On the internet access question it is hard to say.  If you setup a route to
the internet and then you may be able to add an access list to the vlan to
only allow certain ip's onto the internet.

Subject: [AspNetAnyQuestionIsOk] Off Topic, need Cisco help

 


Sorry about asking here, but I need some help, and can't seem to find it.

Does anyone know any good list like this one for Cisco switch help? I'll
include the question below just in case someone here can help.

I've got a Cisco Catalyst 2924XL That I've been using for a few years. We
have outgrown our IP allocation, but the new subnet I've been given to use
is not contiguous with our current subnet.

I thought there was a way to get all ports to work for both subnets, but I
can't figure out how. If that's not possible should I do it with 2 VLANS? If
I create a VLAN for each subnet, will they still be able to talk between
themselves, or would I need a 3rd VLAN that includes the port to the
internet, with some routing?

Sometimes I think I wear too many hats :(
