5.2.11 Broadcast Storm Protection

Function name: Broadcast Storm Protection configuration

Function description: When the broadcast packets received by the switch exceed the threshold configured, the port will be blocked for a period of time that can be set. After a configured time, the switch will detect whether the broadcast packets received on the port still exceed the threshold. If the broadcast traffic is still higher than the configured threshold, the port will be closed for a period of time again. If the broadcast traffic is under the threshold, the port will re-open and forward the packets normally.
