摘要:
A network device for uniform distribution of non-unicast traffic, such as layer 2 broadcast, layer 2 multicast, unknown unicast and layer 3 multicast on a truch group. The network device includes at least one trunk group including a plurality of physical ports. The network device is connected to at least one other network device by a number of the plurality of physical ports. The network device also includes a table with a plurality of entries, wherein each entry is associated with the number of the plurality of physical ports on the network device. Each entry specifies if a packet should be transmitted on one of the plurality of physical ports. The network device further includes hashing means for hashing a predefined number of bits from predefined fields in the packet to select one entry in the table. The selected entry is used to identify a destination port. The network device also includes transmitting means for transmitting the packet to the destination port.
