DIGITAL VNswitch 900FF

This document is an installation and configuration manual for the DIGITAL VNswitch 900FF, a high-throughput, SNMP-manageable multiport network switch designed to link Fiber Distributed Data Interface (FDDI) backbones. The manual details how to install and set up the VNswitch 900FF module and its Fiber Distributed Data Interface (Mod-FDDI) modular media interface cards into either a DIGITAL MultiSwitch 900 chassis or a standalone DEChub ONE/ONE-MX docking station.

Key features and functionalities covered include:

• Hot-swapping capabilities for both the module and its interface cards.
• Comprehensive configuration and management options via SNMP and Command Line Interface (CLI), supporting auto-configuration, firmware upgrades using nonvolatile flash memory and TFTP, and a built-in SNMP agent with GUI support.
• Bridging features such as high-speed traffic filtering and forwarding, full line-rate performance (up to 750,000 packets/second), and compliance with IEEE 802.1d spanning tree protocol.
• FDDI specific features including full-duplex operation, configuration in tree or dual-ring topologies, and the ability for ports to emulate concentrator ports.
• VLAN Secure Domains (VSD) support for grouping ports, joining VSDs across the VNbus, and creating distributed multicast domains.

The document also provides instructions for connecting the setup port cable, configuring IP addresses using menu-driven interfaces in different host environments, troubleshooting common issues using LED indicators, and includes detailed connector information and product specifications.
