We have a network with 3 subnets, 1 for workstations, 1 with private addresses for networked printers and switches, and 1 used by another company sharing our network infrastructure. There are no vlan's configured since traffic is fairly light. There is a 2948G-L3 at the core of the network so the 3640 Internet access router doesn't have to move traffic between the subnets. I would like to purchase a 3550-12T to take advantage of gigabit uplinks from outbuildings and other wings in the main office building. To keep the configuration simple, is it possible to configure the 3550 like the 2948G-L3 so the entire switch does routing and avoid having to configure layer3 or layer2 on a per port basis?
Thanks for any information.
