Table 60 IEEE 802.3 organizationally specific TLVs

4.IEEE 802.3 organizationally specific TLVs

Type

Description

 

Contains the rate and duplex capabilities of the sending port, support

MAC/PHY Configuration/Status

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.

 

 

 

Indicates the support of the port for link aggregation, the aggregation

Link Aggregation

capability of the port, and the aggregation status (whether the link is in

 

an aggregation).

 

 

Maximum Frame Size

Indicates the supported maximum frame size. It is 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 provide a cost-effective and easy-to-use solution for deploying voice devices in Ethernet. LLDP-MED TLVs are shown in 1.

1.LLDP-MED TLVs

Type

Description

LLDP-MED Capabilities

Allows a MED endpoint to advertise the supported LLDP-MED TLVs and its

device type.

 

 

 

 

Allows a network device or MED endpoint to advertise LAN type and VLAN ID

Network Policy

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.

 

 

 

Allows a MED endpoint to advertise its asset ID. The typical case is that the

Asset ID

user specifies the asset ID for the endpoint to facilitate directory management

 

and asset tracking.

 

 

 

Allows a network device to advertise the appropriate location identifier

Location Identification

information for an endpoint to use in the context of location-based

 

applications.
