Storm Threshold
to use threshold limits to prevent broadcast/multicast overload.
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).
• An absolute maximum number of messages per port.
The
Storm Threshold
parameters let you specify a set of thresholds for each port of the unit, identifying separate values
for the number of broadcast messages per second and multicast messages per second.
When the number of frames for a port or identified station exceeds the maximum value per second, the unit ignores all
subsequent messages issued by the particular network device, or ignores all messages of that type.
The following parameters are configurable:
•
Per Address Threshold:
Enter the maximum allowed number of packets per second.
•
Ethernet Threshold:
Enter the maximum allowed number of packets per second.
•
Wireless Threshold:
Enter the maximum allowed number of packets per second.
