Cisco's Catalyst 3000 system is a high-performance, stackable switching platform consisting of the Catalyst 3000 series switches and Catalyst 3000 Matrix. This switch platform is the first stackable switching architecture to deliver Layer 2 and Layer 3 functions in its stackable software for growing workgroup applications. The flexible design enables additional switching capacity without migrating to a new platform.The stackable architecture of the Catalyst 3000 switch series allows it to cost-effectively address a wide spectrum of applications. Stacked switches can be managed as one logical entity IP address, overcoming one of the primary obstacles of managing stackable devices.
