Manual VLAN Configuration
You can configure VLAN for the Internet port and PC port manually. Before configuring VLAN on the phones, you
need to obtain the VLAN ID from your network administrator.
For CP920 phones, you can only configure VLAN for the Internet port manually, because they only have an Internet
port.
The following table lists the parameters you can use to configure VLAN manually.
