ACC-FLASH::accBrFiltPatternDisp controls what happens to a packet when it matches a bridge filter pattern (forward, forward with priority, or discard). A network operator configures this to control traffic behavior—for example, prioritizing certain traffic types for latency-sensitive applications or dropping unwanted broadcast traffic to prevent congestion. Setting this to 'forward-priority' on videoconferencing traffic ensures those packets get through the bridge with minimal delay.
