1.2.2 Limiting Traffic on individual Ports
By performing the following configurations, you can limit different types of incoming
traffic on individual ports. When a type of incoming traffic exceeds the threshold you set,
the system drops the packets exceeding the traffic limit to reduce the traffic ratio of this
type to the reasonable range, so as to keep normal network service.
