Type
Management Address TLV
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.
Currently, protocol identity TLVs can only be received on Switch 4500.
2) IEEE 802.3 defined LLDP TLVs include the following:
MAC/PHY configuration/status TLV, which carries port configuration, such as port speed, duplex
state, whether port speed auto-negotiation is supported, the state of auto-negotiation, current
speed , and current duplex state.
Power via MDI TLV, which carries information about power supply capabilities .
Link aggregation TLV, which carries the capability and state of link aggregation.
Maximum frame size TLV, which carries the maximum frame size supported, namely, MTU
(maximum transmission unit).
MED related LLDP TLVs
LLDP-MED TLVs provide multiple advanced applications for VoIP, such as basic configuration, network
policy configuration, and address and directory management. LLDP-MED TLVs satisfy the voice device
manufacturers' requirements for cost-effectiveness, easy deployment, and easy management. In
addition, LLDP-MED TLVs make deploying voice devices in Ethernet easier.
LLDP-MED capabilities TLV, which carries the MED type of the current device and the types of the
LLDP MED TLVs that can be encapsulated in LLDPDUs.
Network policy TLV, which carries port VLAN ID, supported applications (such as voice and video
services), application priority, and the policy adopted.
Extended power-via-MDI TLV, which carries the information about the power supply capability of
the current device.
Hardware revision TLV, which carries the hardware version of an MED device.
Description
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.
