Table 1-5 IEEE 802.3 organizationally specific TLVs
Type Description
MAC/PHY Configuration/Status
Contains the rate and duplex capabilities of the sending port,
support for auto negotiation, enabling status of auto
negotiation, and the current rate and duplex mode.
Power Via MDI Contains Power supply capability of the port.
Link Aggregation
Indicates the support of the port for link aggregation, the
aggregation capability of the port, and the aggregation status
(that is, whether the link is in an aggregation).
Maximum Frame Size
Indicates the supported maximum frame size. It is now the
MTU of the port.
LLDP-MED TLVs
LLDP-MED TLVs provide multiple advanced applications for voice over IP (VoIP), such as basic
configuration, network policy configuration, and address and directory management. LLDP-MED TLVs
satisfy the voice device vendors’ requirements for cost effectiveness, ease of deployment, and ease of
management. In addition, LLDP-MED TLVs make deploying voice devices in Ethernet easier.
LLDP-MED TLVs are shown in Table 1-6 :
Table 1-6 LLDP-MED TLVs
Type Description
LLDP-MED Capabilities
Allows a MED endpoint to advertise the supported
LLDP-MED TLVs and its device type.
Network Policy
Allows a network device or MED endpoint to advertise LAN
type and VLAN ID of the specific port, and the Layer 2 and
Layer 3 priorities for a specific set of applications.
Extended Power-via-MDI
Allows a network device or MED endpoint to advertise
power-related information (according to IEEE 802.3AF).
Hardware Revision
Allows a MED endpoint device to advertise its hardware
version.
Firmware Revision Allows a MED endpoint to advertise its firmware version.
Software Revision Allows a MED endpoint to advertise its software version.
Serial Number
Allows an LLDP-MED endpoint device to advertise its serial
number.
Manufacturer Name Allows a MED endpoint to advertise its vendor name.
Model Name Allows a MED endpoint to advertise its model name.
Asset ID
Allows a MED endpoint to advertise its asset ID. The typical
case is that the user specifies the asset ID for the endpoint to
facilitate directory management and asset tracking.
Location Identification
Allows a network device to advertise the appropriate location
identifier information for an endpoint to use in the context of
location-based applications.
