IP Phone Manual

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 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 phone WAN port,

one kind of packets will go to the 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 Prio-

rity, 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 phone IP address and the same

VID will be accept by the phone. If the incoming packets with the phone IP

address but the different VID then the packets will be discard by the phone.

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 phone can

help you to filter the wrong incoming packets. You can separate the other de-

vice connectd behind the phone into 4 VLAN group. You can set different VID

for these 4 groups. When the incoming packets go through the phone WAN

port then the phone will check the VID, if the packets is not going to the pho-

ne (with the phone IP address and the correct VID), and the VID is not these

four VID you set, then the packets will be discard by the phone.

If there is nothing need to change, please click the Save Change Item in the
