Three-port switch and VLAN functionality
System overview
The Full VLAN support feature can create telephone Voice-VLAN and PC Data-VLAN on the
three-port switch of the IP Deskphone manually and automatically (see
Figure 30: Voice-VLAN
and Data VLAN on page 196).
If both Data and Voice VLANs are enabled on a three-port switch, only the frames with Data
and Voice VLAN tagged go to networks. The IP Deskphone receives only the frames with Voice
VLAN tagged and sends the frames with Voice VLAN tagged, while PC or Local Networks
receive all kinds of frames.
When only voice VLAN is enabled on three-port switch, all kinds of frames go to the Network,
the IP Deskphone receives only the frames with Voice VLAN tagged and send all frames with
Voice VLAN tagged. PC or Local Networks receive all kinds of frames.
