I have several switches in my public network each connecting two or
three devices on seperate networks.  I thought it would be a good idea
to consolidate them into one switch with a VLAN for each network with

understand.  I was wondering if anyone does this and how to make it
secure.

Thanks.

Essentially you are talking about creating the vlans centrally, using
VTP to propagate out the VLANs, using your existing routers to service
those networks (or perhaps consolidate those as well to a central l3
switch or router).  This isn't that difficult, and it depends if you
are consolidating onto a catalyst or ios based switch for config
references.  You also would need to control 'security' at the
routers.  If you don't want traffic between subnets, you'll need to
ensure that you aren't advertising the networks between you routers,
or you have access-control lists if you are routing centrally.

My plan is to use one switch that has one VLAN to connect every pair
of devices. Each pair of devices is in on a separate network. Each
port will be configured as an access port e.g. switchport mode
access. There will be no connections from this switch to any other
switches, thus no need for trunks. I am replacing several small
switches. The switch is a Catalyst switch with IOS.

Your comments will be welcomed.

Thanks
