The
Catalyst 2948G-L3 switch is a fixed-configuration Layer 3 (L3) Ethernet
switch featuring wire-speed switching for Internet Protocol (IP), Internetwork
Packet Exchange (IPX), and IP multicast.
The
Catalyst 2948G-L3 switch provides non-blocking routing and switching for
IP, IPX, and IP multicast while also offering wire-speed Layer 2 switching
for non-routable protocols such as NetBIOS and DECnet local-area transport
(LAT). This capability allows network managers to augment their multi-
protocol backbones with the Catalyst 2948G-L3 without having to build
parallel networks, as is often required with IP-only switches.
