When a HighBroadcastRate fault occurs, IP Performance Manager generates a PerformanceException for the affected system or VLAN. IP Performance Manager detects a HighBroadcastRate fault when the input packet broadcast percentage exceeds the BroadcastThreshold. The input packet broadcast percentage calculates the percentage of total capacity that was used to receive broadcast packets.
The BroadcastThreshold is contained in both the Generic Interface/Port Performance setting and the Ethernet Interface/Port Performance setting. Chapter 7, "Customizing Polled Data Thresholds," in the VMware Smart Assurance IP Management Suite Configuration Guide describes these settings.
