VLAN Setting: You can set the VLAN setting in this page. There are two parts in this page. First one is to set the
packets related to the TA, and the second parts is if you use the VLAN setting in the NAT Mode.
3.5.6.1
There are two kind of destination packets will come from the TA’s WAN port, one kind of packets will go to the
TA, the other will go through the LAN port to the PC.
3.5.6.2
VLAN Packets: if you enable the first VLAN Packets and set the VID, User Priority, and CFI,
then all the
incoming packets will be check with the IP Address and the VID.
3.5.6.3
VID: You can follow your service provider to set your VID.
3.5.6.4
User Priority: Defines user priority, giving eight (2^3) priority levels. IEEE 802.1P defines the operation for these
3 user priority bits. Usually this will be defined by your service provider.
3.5.6.5
CFI: Canonical Format Indicator is always set to zero for Ethernet switches. CFI is used for compatibility reason
between Ethernet type network and Token Ring type network. If a frame received at an Ethernet port has a CFI set to 1,
then that frame should not be forwarded as it is to an untagged port.
3.5.6.6
When you enable the first VLAN Packets and set the VID, User Priority, and CFI,
then all the incoming packets
with the TA’s IP address and the same VID will be accept by the TA. If the incoming packets with the TA’s IP address but
the different VID then the packets will be discard by the TA. The Other incoming packets with different IP address will go
through the LAN port to the PC.
3.5.6.7
NAT VLAN Setting: When you set your device in NAT mode, the TA can help you to filter the wrong incoming
packets. You can separate the other device connectd behind the TA into 4 VLAN group. You can set different VID for
these 4 groups. When the incoming packets go through the TA’s WAN port then the TA will check the VID, if the packets
is not going to the TA(with the TA’s IP address and the correct VID), and the VID is not these four VID you set, then the
packets will be discard by the TA.
3.5.6.8
