NOTE: The maximum supported size of the LLDP PDUs is 1500 bytes on the transmission side. If the size of the TLVs that are
transmitted exceeds 1500 bytes, optional TLVs may not be included in the PDU.
Optional TLVs
OS10 supports basic TLVs, IEEE 802.1, and 802.3 organizationally-specic TLVs, and TIA-1057 organizationally-specic TLVs. A basic TLV is
an optional TLV sub-type. This kind of TLV contains essential management information about the sender.
A professional organization or vendor denes organizationally-specic TLVs. They have two mandatory elds, in addition to the basic TLV
elds.
