Monitoring the Network 45
Broadcast Storm Protection
The CenturyStack 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, the following actions can be
taken: (1) sending a trap, (2) partition the port, or (3) both sending a trap
and partitioning the port. 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
Users can configure the port broadcast threshold value and optional
module threshold value of each segment.
The Segment Rate Threshold, Port Rate Threshold, and Optional Module
Rate Threshold determines whether the broadcast storm exists or not.
