vlan

We have a medium sized network of around 200 nodes and are currently in the process of replacing old daisy chained switches with stack-able or chassis style switches. Right now our network is broken up via subnet; production, management, IP, etc each on a separate subnet. Does anyone have an opinion on whether creating Vlan's instead of subnets would be more beneficial? Our general goal is to prevent bottlenecks, separate traffic for security, and to manage traffic with more ease.

I use give my router the first address in this pool and then use 1-to-1 NAT for all the servers behind the firewall, so that… >>> More
