This chapter provides information on the Catalyst 1600 Token Ring switch. The information is organized into the following sections:
The Catalyst 1600 is an 8- or 12-port Token Ring switch with optional FDDI support. It provides campus and building backbone segment switching as well as dedicated full-duplex connections to file servers. The Catalyst 1600 is the ideal solution for network administrators who need to replace slow, PC-based source-route bridges with a fast, cost-effective, manageable solution. Other applications include sites with existing router-based collapsed backbones where there is a need to centralize servers and replace existing 16-Mbps backbone rings with a switch.
The modular chassis comes with a supervisor engine in the top slot and four-port Token Ring modules in the next two slots, for a total of eight Token Ring ports. An optional slot is provided to add another four-port module or to add an FDDI or a future ATM high-speed interface. With support for source-route bridging and the implementation and management of virtual LANs (VLANs), the Catalyst 1600 Token Ring switch delivers all of the performance and management requirements for switched Token Ring server and backbone applications.
The four-slot chassis features a switch-activated LCD display to provide real-time port statistics and status information. The Catalyst 1600 supports a required Supervisor Engine and a combination of interface modules. The Supervisor Engine module enables switching and network management and provides a monitoring port for out-of-band management and a console interface for configuration.
The Catalyst 1600 Token Ring switch includes the following components:
