WS-C3920 Overview

The Cisco WS-C3920 Catalyst 3920 is a legacy Token Ring switch designed for enterprise environments that required high-performance Token Ring networking before Ethernet became the standard. It provides 24 Token Ring LAN ports, making it suitable for connecting multiple Token Ring devices in large campus or office networks. The switch includes 1 x stacking module, enabling multiple Catalyst 3920 units to be interconnected for scalability and simplified management, allowing them to operate as a single logical unit.As part of the early Cisco Catalyst family, the 3920 was engineered to deliver high-speed switching for Token Ring traffic, offering lower latency and improved reliability compared to traditional Token Ring hubs. It supported full-duplex operation, which doubled throughput per port.
