Port Shutdown with Broadcast Storm

A LAN broadcast storm arises when an excessively high rate of broadcast packets flood the LAN. Occurrence of LAN broadcast storm disrupts traffic and degrades network performance. To prevent LAN traffic from being disrupted, the use of fault-finder commands trigger a port disablement when a broadcast storm is detected. Commands can be used only to support broadcast traffic and not multicast and unicast types of traffic.

The waiting period range for re-enabling ports is 0 to 604800 seconds. The default waiting period to re-enable a port is zero which prevents the port from automatic re-enabling.

Avoid port flapping when choosing the waiting period by considering the time to re-enable carefully.
