Packets

for the purpose of limiting the network bandwidth not being occupied by those storm-like packets. All the packet type filtering conditions can be active at the same time. Besides, the user can configure Broadcast Storm Rate of this switch to limit the ingress broadcast storm rate.

Flooded Unicast:

LAN switches use forwarding tables to direct traffic to specific ports based on the VLAN number and the destination MAC address of the frame. When there is no entry corresponding to the frame’s destination MAC address in the incoming VLAN, the unicast frame will be sent to all forwarding ports within the respective VLAN, which causes flooding.

Multicast:

Multicast is the delivery of information to a group of destinations simultaneously using the most efficient strategy to deliver the messages over each link of the network only once, creating copies only when the links to the destinations split.

IP Multicast Packets:

An IP Multicast group address is used by sources and the receivers to send and receive packets. Sources use the group address as the IP destination address in their data packets. Receivers use this group address to inform the network that they are interested in receiving packets sent to that group.
