D-Link EasySmart Switch User Manual Figure 53 - QoS > 802.1p Default Priority Queuing Mechanism: Select Strict Priority to process the packets with the highest priority first. Select WRR (Weighted Round-Robin) to process packets according to the weight of each priority. When a priority level has reached its egress weight, the system will process the packets in the next level even if there are remaining packets. D-Link EasySmart Switch system's weight of priority levels are: 8 (Highest), 4 (High), 2 (Medium) and 1 (Low) packet. By default, the queuing mechanism is Strict Priority. QoS > Storm Control The Storm Control feature provides the ability to control the receive rate of broadcast, multicast, and unknown unicast packets. Once a packet storm has been detected, the Switch will drop packets coming into the Switch until the storm has subsided. Figure 54 - QoS > Storm Control Storm Control Type: User can select the different Storm type from Broadcast Only, Multicast & Broadcast, and Multicast & Broadcast & Unknown Unicast. Threshold (pps): If storm control is enabled (by default it is disabled), the threshold can be set from 1 to 1,000,000pps. Click Apply for the settings to take effect. QoS > Bandwidth Control The Bandwidth Control page allows network managers to define the bandwidth settings for a specified port's transmitting and receiving data rates. 30
