HP V1910 manual 232

LLDPDU TLVs fall into the following categories:

∙Basic management TLVs

∙Organizationally (IEEE 802.1 and IEEE 802.3) specific TLVs

∙LLDP-MED (media endpoint discovery) 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 thus are optional to LLDPDUs.

Table 58 Basic management TLVs

2 lists the basic management TLV types. Some of them must be included in every LLDPDU.

2.Basic LLDP TLVs

Type	Description	Remarks
Chassis ID	Bridge MAC address of the sending device.
	ID of the sending port.
	If the LLDPDU carries LLDP-MED TLVs, the port ID TLV carries
Port ID	the MAC address of the sending port or the bridge MAC in
	case the port does not have a MAC address. If the LLDPDU	Mandatory
	carries no LLDP-MED TLVs, the port ID TLV carries the port
	name.
Time To Live	Life of the transmitted information on the receiving device.
End of LLDPDU	Marks the end of the TLV sequence in the LLDPDU.
Port Description	Port description of the sending port.
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	Optional
	enabled primary functions.
	Management address used to reach higher level entities to
Management Address	assist discovery by network management, and the interface
	number and object identifier (OID) associated with the
	address.

Table 59 IEEE 802.1 organizationally specific TLVs

3.IEEE 802.1 organizationally specific TLVs

Type	Description
Port VLAN ID	PVID of the sending port.
Port And Protocol VLAN ID	Port and protocol VLAN IDs.
VLAN Name	A specific VLAN name on the port.
Protocol Identity	Protocols supported on the port.

NOTE:

HP V1910 Switch Series can receive but cannot send protocol identity TLVs.
