5.8.2 IGMP Snooping Status Table

Multicast filtering is the system by which the end stations only receive multicast traffic if they

have registered to join specific multicast groups. With multicast filtering, network devices only

forward multicast traffic to the ports that are connected to registered end stations.

5.9 QoS (Traffic Prioritization)

Network traffic is always unpredictable and the only basic assurance that can be offered is the

best effort traffic delivery. To overcome this challenge, Quality of Service (QoS) is applied

throughout the network. This ensures that network traffic is prioritized according to specified

criteria and receives preferential treatments.

Traffic Prioritization includes three modes: port base, 802.1p/COS, and TOS/DSCP. By traffic

prioritization function, users can classify the traffic into four classes for differential network

application. All of Antaira’s industrial managed switches support four priority queues.
