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.

1.2.3 Enabling Flow Control on a Port
Flow control is enabled on both the local and peer switches. If congestion occurs on the
local switch:
z
The local switch sends a message to notify the peer switch of stopping sending
packets to itself temporarily.
z
The peer switch will stop sending packets to the local switch or reduce the sending
rate temporarily when it receives the message; and vice versa. By this way, packet
loss is avoided and the network service operates normally.
