VAX P.S.I. (Packetnet System Interface) Management Guide

This document, the VAX P.S.I. (Packetnet System Interface) Management Guide, is designed for network managers to configure, manage, and secure VAX PSI on a VMS system for communication via Packet Switching Data Networks (PSDNs). It covers initial setup using Network Control Program (NCP) commands, including defining lines, circuits, objects, and destinations for various system modes (Native, Multi-host, Access, Combination), and setting up Data Link Mapping (DLM). The guide also provides instructions on testing the VAX PSI configuration with the Configuration Test Program (CTP). A substantial section is dedicated to PSI Security, detailing how to control incoming and outgoing network access through concepts like agents, objects, rights identifiers, and Access Control Lists (ACLs). Additionally, it explains the PSI Accounting utility for recording and reporting VAX PSI usage data for purposes such as cost analysis or performance monitoring, along with reference information on flow control parameter negotiation.
