VLAN
The purpose of VLAN configurations on the phone is to insert a tag with VLAN information to the packets generated
by the phone. When VLAN is properly configured for the ports (Internet port and PC port) on the phone, the phone
will tag all packets from these ports 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 phone also supports the automatic discovery of VLAN via LLDP, CDP or
DHCP. The assignment takes effect in this order: assignment via LLDP/CDP, manual configuration, then assign-
ment via DHCP.
For more information on VLAN, refer to VLAN Feature on Yealink IP Phones.

LLDP Configuration
LLDP (Linker Layer Discovery Protocol) is a vendor-neutral Link Layer protocol, which allows the phones to advert-
ise its identity and capabilities on the local network.
When LLDP feature is enabled on the phones, the phones periodically advertise their own information to the dir-
ectly connected LLDP-enabled switch. The phones can also receive LLDP packets from the connected switch and
obtain their VLAN IDs.
The following table lists the parameters you can use to configure LLDP.
