VLAN Settings: ou 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 IP Phone, and the second parts is if you use the VLAN
setting in the NAT Mode.
There are two kind of destination packets will come from the WAN port of IP Phone, one
kind of packets will go to the IP Phone , 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, then 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, then all
the incoming packets with the IP address of IP Phone and the same VID will be accept by
the IP Phone. If the incoming packets with theIP Phone IP address but the different VID
then the packets will be discard by the IP IPhone. The Other incoming packets with
different IP address will go through the LAN port to the PC.
NAT VLAN Setting: When you set your device in NAT mode, the IP Phone can help you to
filter the wrong incoming packets. You can separate the other device connectd behind the
IP Phone into 4 VLAN group. You can set different VID for these 4 groups. When the
incoming packets go through the WAN port of IP Phone then the IP Phone will check the
VID, if the packets is not going to the IP Phone (with the IP address of IP Phone and the
correct VID), and the VID is not these four VID you set, then the packets will be discard by
the IP Phone.
