transmitted to the other ports except 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
Field name
explanation
VLAN Enable
Before select it to enable VLAN, you need enable Bridge mode in
LAN config.
VLAN ID Check
Enable
Enable VLAN ID check by selecting it. After enable VLAN ID check,
if VLAN ID of a data package is not the same with the phone’s or a
data package do not have VLAN ID, the data package will be
discarded.
Voice/Data VLAN
differentiated
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 untaged means after using VLAN, only VoIP
packets will add voice VLAN ID. Other data packets will not use
VLAN.
DiffServ Enable
Select it or not to Enable or disable DiffServ.
DiffServ Value
Set DiffServ value, the common value is 0x00.
Voice 802.1P Priority
Specify 802.1P Priority of voice/signal data package.
Data 802.1P Priority
Set 802.1p of data VLAN. Non-VoIP data (such as http, telnet, ping
etc) will use this value to set VLAN package.
Voice VLAN ID
Set VLAN ID of voice/signal data package.
Data VLAN ID
Set 802.1q of data VLAN ID. Non-VoIP data (such as http, telnet,
ping etc) will use this value to set VLAN package.
NOTICE
:
1
)
Startup VLAN, if set Voice/Data VLAN differentiated as Undifferentiated, all packets will
use the Voice VLAN ID as the tag.
2) Startup VLAN, if set Voice/Data VLAN differentiated as tag differentiated and disable 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 enable the
DiffServ, then system will distinguish the voice and data and add the VLAN ID each
other.
