the gateway will no longer set IP address for LAN
physical port
,
LAN and WAN will join in the same
network. Click “Apply”, the gateway will reboot.

5.3.2.3. Qos Config
The gateway support 802.1Q/P protocol and DiffServ configuration. VLAN
functionality can use different VLAN IDs by
setting signal/voice VLAN and data
VLAN. The VLAN application of this device is very flexible.
In chart 1, there is two-layer switch without setting VLAN. Any broadcast frame
will be 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
transmit ion.
Note: chart 2 use red and blue to identify the different VLAN, but in practice, VLAN
uses different VLAN IDs to identify.
