There are two kind of destination packets will come from the TA’s WAN port, one kind of packets will go to the TA,
and the other will go through the LAN port to the PC.
VLAN Packets: if you enable the first VLAN Packets and set the VID, User Priority, and CFI, all the incoming
packets will be check with the IP Address and the VID.
VID: You can follow your service provider to set your VID.
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.
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.
When you enable the first VLAN Packets and set the VID, User Priority, and CFI, 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.
