The use of VLANs improves network performance and
helps to maintain Quality of Service (QoS) for IP phone
calls. Use the Configuration > Network > LAN page to
configure the basic settings for the Data VLAN and the
Voice VLAN.
Notes:
• Refer to the on-screen illustration for the location
of the LAN ports, where you can connect
network devices such as IP phones, Ethernet
switches, and computers. You can position your
mouse pointer over the pointer icon to view the
picture at a larger size.
• The default address scheme for the Data and

existing network requires a different address scheme.
• The Data VLAN settings are unavailable if you choose Topology Option 2 or 3 on the Topology
page.
