the send port. For example, a broadcast information is sent out from port 1 then transmitted to port 2,3and 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 transmition.
Note: chart 2 use red and blue to identify the different VLAN, but in practice, VLAN uses different VLAN IDs to identify.
QoS Configuration

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 packets will add voice VLAN ID. Other data packets will not use VLAN.

tag.
2) Startup VLAN, if set Voice/Data VLAN differentiated as tag differentiated and disables the DiffServ, then system will not
distinguish the voice and data, all packets will use the Voice VLAN ID as the tag.
3) Startup VLAN, if set Voice/Data VLAN differentiated as tag differentiated and enables the DiffServ, then system will
distinguish the voice and data and add the VLAN ID each other.
4) Startup VLAN, if set Voice/Data VLAN differentiated as data untagged, then the packet of the signal/voice will use the
