Note:
For detailed introduction of TLV, please refer to IEEE 802.1AB standard and ANSI/TIA-1057.
In TP-Link switch, the following LLDP optional TLVs are supported.
Port Description TLV
System Capabilities TLV
System Description TLV
System Name TLV
Management Address TLV
Port VLAN ID TLV
Port And Protocol VLAN ID
TLV
VLAN Name TLV
Link Aggregation TLV
MAC/PHY
Configuration/Status TLV
The Port Description TLV allows network management to
advertise the IEEE 802 LAN station's port description.
The System Capabilities TLV identifies the primary functions of
the system and whether or not these primary functions are
enabled.
The System Description TLV allows network management to
advertise the system's description, which should include the
full name and version identification of the system's hardware
type, software operating system, and networking software.
The System Name TLV allows network management to
advertise the system's assigned name, which should be the
system's fully qualified domain name.
The Management Address TLV identifies an address
associated with the local LLDP agent that may be used to
reach higher entities to assist discovery by network
management.
The Port VLAN ID TLV allows a VLAN bridge port to advertise
the port's VLAN identifier (PVID) that will be associated with
untagged or priority tagged frames.
The Port And Protocol VLAN ID TLV allows a bridge port to
advertise a port and protocol VLAN ID.
The VLAN Name TLV allows an IEEE 802.1Q-compatible IEEE
802 LAN station to advertise the assigned name of any VLAN
with which it is configured.
The Link Aggregation TLV indicates whether the link is capable
of being aggregated, whether the link is currently in an
aggregation, and if in an aggregation, the port identification of
the aggregation.
The MAC/PHY Configuration/Status TLV identifies: a)The
duplex and bit-rate capability of the sending IEEE 802.3 LAN
node that is connected to the physical medium; b)The current
duplex and bit-rate settings of the sending IEEE 802.3 LAN
node; c)Whether
auto-negotiation during link initiation or of manual set override
action.
