LLDP and LLDP-MED Support
Link Layer Discovery Protocol (LLDP) and Link Layer Discovery Protocol Media Endpoint Discovery
(LLDP-MED) are supported on your systems. LLDP is a vendor-neutral link layer protocol in the Internet
Protocol Suite used by network devices to advertise their identity and capabilities on an IEEE 802 local
area network (LAN). This protocol runs over the data-link layer only, allowing connected systems running
different network layer protocols to discover information about each other. LLDP-MED is an extension of
LLDP.
Examples of applications that use information discovered by LLDP include:
• Network topology - A network management system (NMS) can accurately represent a map of the
network topology.
• Inventory - A management system can query a switch to learn about all the devices connected to
that switch. The LLDP protocol is formally specified in standards document IEEE 802.1AB.

LLMP-MED Information Discovery
LLDP-MED enables the following information discovery for your systems:
• Auto discovery of LAN policies enabling plug and play networking
• Inventory management, which allows network administrators to track their network devices.
Behavior When LLDP is Enabled
When LLDP is enabled on a system, it discovers VLANs advertised by the network switch and
automatically configures the system for one of the VLANs. If the room system discovers any of the
following VLAN types in LLDP data from the network switch, the system automatically configures itself for
one of them. The chosen VLAN type is based on the order of precedence, as follows:
• Video Conferencing VLAN
• Voice VLAN
• Voice Signaling VLAN
If none of the above VLAN types are found, the room system configures itself for the default or native
LAN of the switch port to which it is connected.
LLDP packets are transmitted regularly so that the network switch (and the neighboring endpoints) are
aware of the system presence on the network.
