Storm Thresholds Button
Click Storm Thresholds to keep broadcast and multicast storms from spreading throughout the
network. Network storms are common and can cause bridges, routers (brouters), workstations,
servers, and PCs to slow down or crash. Storms occur if network equipment is configured incorrectly,
if network software is not functioning properly, or if poorly designed programs such as network
games are used. These settings are disabled by default.
•
Address Threshold
This setting determines the maximum number of broadcast or multicast packets that can
occur during a one-second period before a storm condition is declared for a particular
Ethernet address (host). Once it is determined that a storm is occurring, any additional
broadcast or multicast packets from that host address will be denied until the storm is deter-
mined to be over. The storm will be determined to be over when 30 seconds have passed in
which every one-second period has less then the stated threshold in broadcast or multicast
packets. The settings for broadcast packets and multicast packets are configured indepen-
dently.
