zMAC address duplication: After port configuration synchronization, packets from Secondary VLAN can be forwarded via the promiscuous port untagged, and those from Primary VLAN can be sent via the host port untagged. In order for these packets can be forwarded in unicast via the right port, MAC address duplication is used to expand the VLANs the MAC address is in. Normally, the egress ports for forwarding these packets are identified through MAC address learning. For example the switch in Figure 6-16maintains a MAC address table shown in Table 6-6.The MAC address duplication process has two aspects, that is, duplicating the dynamic MAC addresses learned by the host ports in the secondary VLANs to the Primary VLAN and copying the dynamic MAC addresses learned by the promiscuous ports in the Primary VLAN to the secondary VLANs. As shown in Figure 6-16,supposing the Router sends a packet with the source MAC as mac_2 and the destination Mac as mac_a. The MAC address table on the Switch is changed to the one shown in Table 6-7.

	Destination MAC		VLAN	Egress Port
	mac_a		5	port 5
	mac_2		2	port 2
	mac_3		3	port 3
	Table 6-6 MAC address table before duplication

	Destination MAC		VLAN	Egress Port
	mac_a		5	port 5
	mac_a		2	port 5
	mac_a		3	port 5
	mac_2		2	port 2
	mac_2		5	port 2
	mac_3		3	port 3
	mac_3		5	port 3
