 Organizationally (IEEE 802.1 and IEEE 802.3) specific TLVs
 LLDP-MED TLVs
Basic management TLVs
Basic management TLVs are essential to device management. Organizationally specific TLVs and LLDP-
MED TLVs are used for enhanced device management; they are defined by standardization or other
organizations and are optional to LLDPDUs.
Table 19 lists the basic management TLV types. Some of them are mandatory to LLDPDUs, that is, must be
included in every LLDPDU.

IEEE 802.1 organizationally specific TLVs
HP devices support only receiving protocol identity TLVs.

Layer 3 Ethernet ports do not support IEEE 802.1 organizationally specific TLVs.

VLAN Name
Description
Specifies the bridge MAC address of the sending device
Specifies the ID of the sending port
If the LLDPDU carries LLDP-MED TLVs, the port ID TLV carries the
MAC address of the sending port or the bridge MAC if the port
does not have a MAC address
If the LLDPDU carries no LLDP-MED TLVs, the port ID TLV carries
the port name
Specifies the life of the transmitted information on the receiving
device
Marks the end of the TLV sequence in the LLDPDU
Specifies the port description of the sending port
Specifies the assigned name of the sending device
Specifies the description of the sending device
Identifies the primary functions of the sending device and the
enabled primary functions
Specifies the management address, and the interface number
and OID associated with the address
Description
Specifies the port's VLAN identifier (PVID)
An LLDPDU carries only one TLV of this type
Indicates whether the device supports protocol VLANs and, if so, with which
VLAN IDs these protocols are associated
An LLDPDU can carry multiple different TLVs of this type
Specifies the textual name of any VLAN to which the port belongs
An LLDPDU can carry multiple different TLVs of this type
