Vlan - Yealink SIP-T4X Administration Manual

tagged packets to the corresponding VLAN according to the VLAN ID in the tag as
described in IEEE Std 802.3.
The VLAN feature on IP phones allows simultaneous access for a regular PC. This feature
allows a PC to be daisy chained to an IP phone and the connection for both PC and IP
phone to be trunked through the same physical Ethernet cable.
In addition to manual configuration, the IP phone also supports automatic discovery of
VLAN via LLDP or DHCP . The assignment takes place 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.
