Cisco Catalyst 2948G
Switch
The Catalyst 2948G is a dedicated Ethernet switch featuring
high-performance Layer 2 switching for the wiring closet,
with low cost per port and advanced and proven software
capable of supporting a wide variety of switching features.
This new Catalyst switch provides an efficient, simple,
and cost-effective method for improving performance and
eliminating network congestion with high-speed, high-performance,
Layer 2 intelligent enterprise switching. Fully integrated
into the Catalyst family of switches, the Catalyst 2948G
uses the same Catalyst system software as the industry-leading
Catalyst 5000/5500 Series, thereby ensuring complete interoperability
with existing Catalyst switches.
