Master Hub Configuration & Console Management 109
Broadcast Storm Protection
The Hub periodically monitors the broadcast counters of each hub port to
detect a broadcast storm condition. If a hub port is detected to be causing
a broadcast storm, it is automatically partitioned and a trap is sent to the
network manager. The Hub continually monitors those ports that have
been partitioned to check if the broadcast storm condition still exists. The
partitioned hub port is auto recovered to normal operation once the
broadcast storm condition is released.
Broadcast Storm Protection Menu
You can configure the broadcast threshold value for each port, each
segment, and each optional module. The Segment Rate Threshold, Port
Rate Threshold, and Optional Module Rate Threshold determines whether
the broadcast storm exists or not.
Segment ID: Identifies the 10Mbps segment or the 100Mbps
segment.
Segment Broadcast Packet Rate Threshold: The number of
broadcast packets received on a given segment per second. The
range is 0 to 14,880 packets per second.
