II. Organization defined LLDP TLVs
1) LLDP TLVs defined in IEEE802.1 include the following:
Port VLAN ID TLV, which carries port VLAN ID.
Port and protocol VLAN ID TLV, which carries port protocol VLAN ID.
VLAN name TLV, which carries port VLAN name.
Protocol identity TLV, which carries types of the supported protocols.
Note:
Currently, protocol identity TLVs can only be received on H3C devices.
Type
Marks the end of an LLDPDU.
Carries the bridge MAC address of the
sender
Carries the sending port. For devices
that do not send MED TLVs, port ID
TLVs carry sending port name. For
devices that send MED TLVs, port ID
TLVs carry the MAC addresses of the
sending ports or bridge MAC addresses
(if the MAC addresses of the sending
ports are unavailable).
Carries the TTL of device information
Carries Ethernet port description
Carries device name
Carries system description
Carries information about system
capabilities
Carries the management address, the
corresponding port number, and OID
(object identifier).
If the management address is not
configured, it is the IP address of the
interface of the VLAN with the least
VLAN ID among those permitted on the
port. If the IP address of the VLAN
interface is not configured, IP address
127.0.0.1 is used as the management
address.
