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.
