DECswitch 900EF Router

This document serves as a comprehensive guide for the DECswitch 900EF Router, detailing its installation and configuration within a DEChub 900 MultiSwitch or as a standalone module in a DEChub ONE or DEChub ONE-MX docking station.

The DECswitch 900EF Router provides multiprotocol routing and switching, enabling the interconnection of networks that use both routable (e.g., IP, IPX, AppleTalk, DECnet Phase IV/OSI) and nonroutable protocols. Key features include hot-swap capability, various configuration and management options (such as a command-line interface via local setup port or remote Telnet, TFTP for firmware upgrades, Out-of-Band Management (OBM), and SNMP support). It supports a wide array of routing protocols (e.g., OSPF, RIP, BGP-4) and advanced bridging features, including Spanning Tree Protocol, flexible traffic filtering, and Virtual LAN (VLAN) support for up to 7 logically segmented networks. The router is designed to interconnect six 10 Mb/s Ethernet LANs with a 100 Mb/s Fiber Distributed Data Interface (FDDI) network backbone, ensuring interoperability through adherence to industry standards. An EasyStart feature simplifies initial configuration by allowing server-based file downloads.

The manual systematically covers module components, detailed installation procedures, cable connections (FDDI, AUI, UTP/STP), initial setup via menu-driven interfaces, advanced configuration commands for ports and VLANs, monitoring commands, module removal instructions, LED-based troubleshooting, connector and pin assignments, and full product specifications.
