4.3.3 Rate Control
Rate limiting is a form of flow control used to enforce a strict bandwidth limit at a
port. You can program separate transmit (Egress Rule) and receive (Ingress Rule)
rate limits at each port, and even apply the limit to certain packet types as
described below.
Figure shows you the Limit Rate of Ingress and Egress. You can type the volume
step by 64Kbps in the blank.
4.3.4 Storm Control
The Storm Control is similar to Rate Control. Rate Control filters all the traffic
over the threshold you input by User Interface. Storm Control allows user to
define the rate for specific Packet Types.
