Protocol Filters
4.4.3.4 Storm Detection
This filter parameter can prevent broadcast/multicast storms from spreading
throughout the network. Network storms can burden radio traffic with unnecessary
data transmissions.
Enabled
This parameter enables ( √ ) or disables the Storm Detection filters.
Threshold
The maximum number of broadcast/multicast frames that should be received in one
second is defined in this parameter. When that threshold is exceeded, a broadcast
storm is declared. Every broadcast/multicast frame received will be discarded until it
is determined that the storm is over (see Restart, below). Setting the value for
Threshold is determined by the characteristics of your network.
The default value is 200.
Restart
The broadcast storm is determined to be over when the number of broadcast frames
received for a one second period is less than or equal to the value entered in this
parameter. Setting the value for Restart is determined by the characteristics of
your network.
The default value is 150.
