摘要： A system for hybrid broadcast packet replication for virtual local area networks includes a switch operable to receive a packet with an associated VLAN identifier and replicate the packet. A VLAN bit mask is included in the switch to filter the target destinations for the sending the replicated packets. The mask has a first level that provides to the switch an indication of a VLAN group where a radio of an AP has an associated client device. The mask has a second level where the mask provides to the switch an indication of a WLAN where a radio of an AP has an associated client device. The mask can have a third level where the mask provides to the switch an indication of a list of VLANs in use by each WLAN. The switch can then send those replicated packets filtered through the mask on to target devices of the identified VLAN.
