It is devoted to experimental and theoretical research in elementary particle physics, and to the development of new techniques in high-energy accelerators and elementary particle detectors.SLAC operates a Computer Center with an IBM+ 3090 mainframe; the SAS Sys-temS is used for statistical analysis of accounting data.Elsewhere on site are some 100 DEC' VAX and MicroVAX minicomputers.These machines are all on a Local -Area Network (LAN) using Ethernet' technology.Access to these systems by ASCII terminals is provided by Micom* Digital PABXes, Scorn/Bridge Ethernet Terminal Servers, and DEC-LAT servers.This paper describes how some networkmanagement functions for the Micom and Scorn/Bridge equipment are provided at SLAC.These functions are implemented as a distributed software package running under VMS on a DEC MicroVAX II, with a user interface available under VM on the IBM 3090 and under VMS on the VAXes.This report describes the motivations behind this management software, discusses their implications for the implementation, and how the resulting package has managed to meet the challenges placed upon it.t IBM is a trademark of International Business Machines, Inc. $ SAS is a registered trademark of SAS Institute Inc. f DEC, VAX, MicroVAX, and VMS are trademarks of Digital Equipment Corp.
