VLAN

This window allows users to dene VLAN membership by groups of device ports. Any individual port or trunk can be a member of a VLAN group. A VLAN group is basically a broadcast domain, but any port/trunk is not limited to belonging to only one VLAN group. The forwarding rule is that packets from the source port/trunk will only be forwarded to a destination port/trunk within the same VLAN group. That is, a broadcast/multicast packet will be forwarded to all ports/trunks within the same VLAN group(s) of the source port/trunk except the source port/trunk itself. Unicast packets will be forwarded to the destination port/trunk only if the destination port/trunk is in the same VLAN group as the source port/trunk.

Flood Control

Within a VLAN, the ood control function is provided to decide what to do with incoming unicast packets with unknown destination MAC addresses.

Enable: Packets received with an unknown unicast destination address (DA) will be forwarded to the specied out-link in the same VLAN group. But if the source port (trunk) belongs to more than one VLAN group, then the packet will only be forwarded to one of the out- links.
