摘要： A network device for selecting a port from a trunk group to transmit a unicast packet on the selected port. The network device includes at least one trunk group including a plurality of physical ports. The network device also includes a table with a plurality of entries. Each entry is associated with one trunk group and includes a plurality of fields that are associated with ports in the trunk group. Each entry also includes a hash field that is used to select bits from predefined fields of an incoming unicast packet to obtain an index bit for accessing one of the plurality of fields. The network device further includes transmitting means for transmitting the unicast packet to a port associated with an accessed one of the plurality of fields.
