Configuration

be adapted accordingly to add VLAN information. In this case, the switch will not

forward the received broadcast frames in all ports, but forward the frames in all

ports in the same VLAN.

2. Multicast frame: For the unknown multicast, the switch will broadcast it in the

same vlan, but the switch only forwards the multicast frames to the multicast

group’s port if IGMP Snooping function or the static multicast group has been

configured.

3. Unicast frame: When no VLAN is configured, if the destination MAC addresses

are in the switch MAC table, the switch will directly forward the frames to the

associated ports; when the destination MAC address in a unicast frame is not

found in the MAC table, the switch will broadcast the unicast frame. When VLANs

are configured, the switch will forward unicast frame within the same VLAN. If the

destination MAC address is found in the MAC table but belonging to different

VLANs, the switch can only broadcast the unicast frame in the VLAN it belongs

to.
