NOTE: When deploying voice VLAN feature together with NAC feature, pay attention the following points:
Ø If the tagged mode of the voice VLAN is tag, the packets received from the port are transmitted through the voice VLAN, the packets sent from the port are tagged with the voice VLAN. Ø If the tagged mode of the voice VLAN is untag, the untagged packets received from the port are transmitted through the dynamic VLAN, the packets sent from the port are also untagged. Ø If the tagged mode of the voice VLAN is untag, the received packets tagged with the voice VLAN ID are forwarded through the voice VLAN and if the received packets are tagged with the dynamic VLAN ID then the packets will be forwarded through the dynamic VLAN. The packets will be dropped if the received tagged VLAN ID matches neither the dynamic VLAN nor the voice VLAN.
