In chart 1, there is a layer 2 switch without setting VLAN. Any broadcast frame will be transmitted to the
other ports except the send port. For example, broadcast information is sent out from port 1 then transmitted
to port 2, 3 and 4.
In chart 2, red and blue indicate two different VLANs in the switch, and port 1 and port 2 belong to red
VLAN, port 3 and port 4 belong to blue VLAN. If a broadcast frame is sent out from port 1, switch will
transmit it to port 2, the other port in the red VLAN and not transmit it to port3 and port 4 in blue VLAN. By
this means, VLAN divide the broadcast domain via restricting the range of broadcast frame transmission.
Note: chart 2 use red and blue to identify the different VLAN, but in practice, VLAN uses different VLAN
IDs to identify.

Enable VLAN ID check by selecting it. After enable VLAN ID
check, if VLAN ID of a packet is not the same with the phone’s or a
packet do not have VLAN ID, the packet will be discarded.
After enable VLAN, system will set packets with different type of
VLAN ID. Undifferentiated means after using VLAN, both voip
packets and other data packets will use the voice VLAN ID; tag
differentiated means after using VLAN, voip(signal and voice)
packets will add voice VLAN ID, and other data packets will add
data VLAN ID; data untagged means after using VLAN, only voip
