2) Port configuration and MAC address duplication should be synchronized on the Switch. Port configuration synchronization is completed in the whole configuration progress and MAC address duplication is implemented while FDB is changing. Port configuration synchronization: when configuring promiscuous and host ports for a Private VLAN, the system will automatically add the promiscuous port and the host port synchronously to the corresponding Primary VLAN and Secondary VLAN. Through port configuration synchronization, the promiscuous port forwards the packets from the Primary VLAN as well as from all the Primary VLAN-associated Secondary VLANs; the host port forwards the packets from the Primary VLAN and the Secondary VLAN owning this host port. Here we take a Private VLAN to illustrate port configuration synchronization. As shown in the figure below, Port2, Port3 and Port5 belong to VLAN 2, VLAN 3 and VLAN 5 respectively. Configure VLAN 2 and VLAN 3 as Secondary VLANs, and VLAN5 as Primary VLAN. After this configuration is completed, the settings of these ports are changed as shown in Table 6-5.

In order for these packets can be forwarded in 71
