Port and protocol VLAN ID TLV
You configure this TLV to be advertised or not advertised. This TLV can be repeated several
times within one LLDPDU.
When configured, this TLV allows the port to advertise VLANs and whether the port supports
protocol-based VLANs or not. If no protocol-based VLANs are configured on the port, the TLV
still advertises the port’s capability and sets the VLAN ID value to 0.
As NETGEAR devices are always capable of supporting protocol-based VLANs, after you
configure this TLV, the system always advertises support for this type of VLAN.
By default, after you configure this TLV, the system sends information for all VLANs on the
port. However, as VLAN TLV requires space and the LLDPDU cannot exceed 1500 bytes,
you should configure the port to advertise only specified VLANs.
MAC/PHY configuration/status TLV
You configure this TLV to be advertised or not advertised. After configured, this TLV
advertises autonegotiation and physical layer capabilities of the port. The system adds
information about the speed rate, duplex setting, bit rate, physical interface, and
autonegotiation support and status.
Power via MDI TLV
You configure this TLV to be advertised or not advertised. When enabled, this TLV is included
in the LLDPDU only for those ports that support supplying power over Ethernet (PoE).
This TLV allows network management to advertise and discover the power-via-MDI
capabilities of the sending 802.3 LAN station. The device type field contains a binary value
that represents whether an LLDP-MED device transmitting the LLDPDU is a power sourcing
entity (PSE) or power device (PD), as listed in
Table 20.
Additional PoE information is advertised as well, including the power status, power class, and
pin pairs used to supply power.
Link aggregation TLV
You configure this TLV to be advertised or not advertised. When enabled, this TLV advertises
information on the port’s load-sharing (link aggregation) capabilities and status.
