BACnet Broadcast Traffic

Overview

• Looks at the overall average rate of Broadcast Traffic over the length of the capture.
• Divides the total number of broadcast packets by the length of the capture.
• Fails if: there is an average of more than 10 pps.
• Warning if: the average is 1 – 9.99 pps.

Why it fails

• Left defaults.
• Didn’t properly configure devices based on site scaling up.
• Common things that can broadcast:
• Time
• Events
• Etc.

How to fix it

• Identify the device sending Broadcast Traffic.
• Manually direct the traffic to the appropriate destination devices, rather than broadcasting it.
