Ethernet Communications Server DECnet Router Software

This guide details the installation, configuration, loading, and troubleshooting of the DECnet Router Server V1.1 software. It explains how to deploy this Digital software product on an Ethernet Communications Server hardware unit, enabling adaptive routing between nodes on an Ethernet LAN and those located off it via various synchronous and asynchronous lines.

Key aspects covered include:

• Installation: Procedures for setting up the software on VMS or RSX-11M/M-PLUS host systems, including copying files and creating necessary databases.
• Configuration: Guidelines for designing and configuring single or multiple area DECnet networks, including node addressing, buffer management, and parameters for Ethernet and area routing (Level 1 and Level 2 routers). It details how to modify network and router configuration files to customize settings like passwords, clock frequency, circuit costs, and line speeds.
• Loading & Verification: Methods for loading the software onto the Communications Server hardware unit, monitoring the loading process for event messages, and using an Installation Checkout Procedure (ICP) to verify correct operation.
• Security: Steps to protect configuration files from unauthorized changes on both VMS and RSX hosts.
• Troubleshooting: Common issues encountered during server loading and operation, along with diagnostic steps.

The document emphasizes the DECnet Router Server's role in expanding network size and efficiency, supporting up to 1022 nodes within an area and up to 62 network areas.
