The Catalyst 2948G-L3 Switch is a fixed configuration Layer 3 Ethernet switch featuring wire-speed switching for IP, IPX, IP Multicast. This new Catalyst switch provides the high performance that is required for small to mid size campus backbones with just the right port density- 48 ports of 10/100 with 2 Gigabit Ethernet uplinks. It is ideal for aggregating multiprotocol traffic from multiple wiring closets or workgroup switches such as the Catalyst 1900, 2900, Catalyst 3500, Catalyst 4000, or Catalyst 5000 switches.
