LLDP
LLDP (Linker Layer Discovery Protocol) is a vendor-neutral Link Layer protocol, which allows IP phones 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 the 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 specifically provides support for
voice over IP (VoIP) applications and provides the following capabilities:
• Capabilities Discovery -- allows IP phones to determine the capabilities that the connected switch supports
and has enabled.
• Network Policy -- provides voice VLAN configuration to notify IP phones 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 IP phones are powered, power priority, and how
much power IP phones need.
• Inventory Management -- provides a means to effectively manage IP phones and their attributes such as
model number, serial number and software revision.
TLVs supported by IP phones are summarized in the following table:
