Administrator‘s Guide for Yealink VC110 Video Conferencing Endpoint
60
In addition to manual configuration, the endpoint also supports automatic VLAN
discovery via LLDP or DHCP. The assignment takes effect in the following order:
assignment via LLDP, manual configuration, then assignment via DHCP.
For more information on VLAN, refer to
VLAN Feature on Yealink IP Phones
.
LLDP (Linker Layer Discovery Protocol) is a vendor-neutral Link Layer protocol, which
allows the endpoint to receive and/or transmit device-related information from/to
directly connected devices on the network that are also using the protocol, and store
the information about other devices. LLDP transmits information as packets called LLDP
Data Units (LLDPDUs). An LLDPDU consists of a set of Type-Length-Value (TLV) elements,
each of which contains a particular type of information about the device or port
transmitting it.
LLDP-MED (Media Endpoint Discovery)
LLDP-MED is published by the Telecommunications Industry Association (TIA). It is an
extension to LLDP that operates between endpoint devices and network connectivity
devices. LLDP-MED provides the following capabilities for the endpoint:

Capabilities Discovery -- allows LLDP-MED endpoint to determine the capabilities
that the connected switch supports and has enabled.

Network Policy -- provides voice VLAN configuration to notify the endpoint which
VLAN to use and QoS-related configuration for voice data. It provides a ―plug and
play‖ network environment.

Power Management -- provides information related to how the endpoint is
powered, power priority, and how much power the endpoint needs.

Inventory Management -- provides a means to effectively manage the endpoint
and its attributes, such as model number, serial number and software revision.
TLVs supported by the endpoint are summarized in the following table:
TLV Type TLV Name Description
Mandatory TLVs
Chassis ID The network address of the endpoint.
Port ID The MAC address of the endpoint.
Time To Live
Seconds until data unit expires.
The default value is 180s.
End of LLDPDU Marks end of LLDPDU.
Optional TLVs System Name
Name assigned to the endpoint.
The default value is ―VC110‖.
