Yealink CP860 [267/417] Procedure

Configuring Advanced Features

255

VLAN (Virtual Local Area Network) is used to logically divide a physical network into

several broadcast domains. VLAN membership can be configured through software

instead of physically relocating devices or connections. Grouping devices with a

common set of requirements regardless of their physical location can greatly simplify

network design. VLANs can address issues such as scalability, security, and network

management.

The purpose of VLAN configurations on the IP phone is to insert tag with VLAN

information to the packets generated by the IP phone. When VLAN is properly

configured for the internet port on the IP phone, the IP phone will tag all packets from

this port with the VLAN ID. The switch receives and forwards the tagged packets to the

corresponding VLAN according to the VLAN ID in the tag as described in IEEE Std 802.3.

In addition to manual configuration, the IP phone also supports automatic discovery of

VLAN via LLDP or DHCP. The assignment takes effect in this order: assignment via LLDP,

manual configuration, then assignment via DHCP.

VLAN Discovery via DHCP

IP phones support VLAN discovery via DHCP. When the VLAN Discovery method is set to

DHCP, the IP phone will examine DHCP option for a valid VLAN ID. The predefined

option 132 is used to supply the VLAN ID by default. You can customize the DHCP option

used to request the VLAN ID.
