AntipassbackData StorageGlobal antipassback increases the size of the card antipassback record, andreduces the amount of space available for card storage. Systems with verylarge databases might require additional SIMM storage.Configuration LimitationsGlobal antipassback is not supported on:• apC• Dialup iSTAR configurations.• iSTAR configurations with more than one C•CURE 800/8000 host.Although C•CURE Central does not share global antipassback information,individual C•CURE 800/8000 systems within C•CURE Central can be configuredfor global antipassback protection within their respective clusters.Configuration ExamplesThis section provides examples of good and poor practices for configuringiSTAR global antipassback.General ConsiderationsGlobal antipassback configurations that optimize performance are designedto:• Maximize processing by the iSTAR master.Performance is most efficient when the iSTAR master processes access forpersonnel within the cluster they access most frequently.• Minimize access that requires host intervention.• Eliminate access across slow or unreliable networks.High Performance ConfigurationFigure 2-9 on page 2-44 shows a configuration that uses global antipassback toenforce area lockout.C•CURE 800/8000 Software Configuration Guide 2–43
