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
The Port Description TLV allows network management to
advertise the IEEE 802 LAN station's port description.
System Capabilities TLV
The System Capabilities TLV identifies the primary functions of
the system and whether or not these primary functions are
enabled.
System Description TLV
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.
System Name TLV
The System Name TLV allows network management to
advertise the system's assigned name, which should be the
system's fully qualified domain name.
Management Address TLV
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.
Port VLAN ID TLV
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.
Port And Protocol VLAN ID
TLV
The Port And Protocol VLAN ID TLV allows a bridge port to
advertise a port and protocol VLAN ID.
VLAN Name TLV
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.
Link Aggregation TLV
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.
MAC/PHY
Configuration/Status TLV
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 these settings are the result of
auto-negotiation during link initiation or of manual set override
action.
