1-4
Type Description Remarks
System Name Assigned name of the sending device
System Description Description of the sending device
System Capabilities
Identifies the primary functions of the sending device and
the enabled primary functions
Management
Address Management address, and the interface number and OID
(object identifier) associated with the address
2) IEEE 802.1 organizationally specific TLVs
Table 1-4 IEEE 802.1 organizationally specific TLVs
Type Description
Port VLAN ID
Port’s VLAN identifier (PVID). An LLDPDU carries only one TLV of this
type.
Port And Protocol VLAN
ID
Indicates whether the device supports protocol VLANs and, if so, what
VLAN IDs these protocols will be associated with. An LLDPDU can
carry multiple different TLVs of this type.
VLAN Name
Textual name of any VLAN to which the port belongs. An LLDPDU can
carry multiple different TLVs of this type.
Protocol Identity
Indicates protocols supported on the port. An LLDPDU can carry
multiple different TLVs of this type.
Currently, H3C devices only support receiving protocol identity TLVs.
3) IEEE 802.3 organizationally specific TLVs
Table 1-5 IEEE 802.3 organizationally specific TLVs
Type Description
MAC/PHY Configuration/Status
Contains the bit-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 the power supply capability of the port, including the
Power over Ethernet (PoE) type, which can be Power Sourcing
Equipment (PSE) or Powered Device (PD), PoE mode, whether
PSE power supply is supported, whether PSE power supply is
enabled, and whether the PoE mode is controllable.
Link Aggregation
Indicates the aggregation capability of the port (whether the link
is capable of being aggregated), and the aggregation status
(whether the link is in an aggregation).
Maximum Frame Size
Indicates the supported maximum frame size. It is now the MTU
of the port.
