The Smart Choice for Token Ring Networks
Cisco leads the industry in providing integrated switching solutions for Token Ring networks. Whether you plan to stay with Token Ring or migrate to Ethernet, the smart choice is a Cisco switched network. With high-speed support for native Token Ring frames over Inter-Switch Link (ISL), Asynchronous Transfer Mode (ATM), or Fast/Gigabit Ethernet, a single backbone can provide transport of both Ethernet and Token Ring virtual LANs (VLANs). In addition, Cisco IOSŪ software provides inter-VLAN routing and bridging, including Token Ring-to-Ethernet conversion. Finally, the CatalystŪ 3900 family provides the lowest price per port for 4/16-Mbps Token Ring switching to the desktop, making hub replacement cost effective. With Cisco's switching solutions, Token Ring customers no longer have to worry about the future.
