Storm Threshold
Storm Threshold is an advanced Bridge setup option that you can use to protect the network against data overload by:
• Specifying a maximum number of frames per second as received from a single network device (identified by its MAC
address).
• Specifying an absolute maximum number of messages per interface.
The Storm Threshold parameters allow you to specify a set of thresholds for each interface of the AP, identifying separate
values for the number of broadcast messages/second and Multicast messages/second.
When the number of frames for an interface or from a single network device exceeds the maximum value per second, the
AP will ignore all subsequent messages in that second received on that interface or from that network device.
• Address Threshold: Enter the maximum allowed number of packets per second.
• Ethernet Threshold:
Enter the maximum allowed number of packets per second.
