Optional TLVs
The Dell EMC Networking OS supports these optional TLVs: management TLVs, IEEE 802.1 and 802.3 organizationally specific TLVs, and
TIA-1057 organizationally specific TLVs.
Management TLVs
A management TLV is an optional TLVs sub-type. This kind of TLV contains essential management information about the sender.
Organizationally Specific TLVs
A professional organization or a vendor can define organizationally specific TLVs. They have two mandatory fields (as shown in the
following illustration) in addition to the basic TLV fields.
Figure 68. Organizationally Specific TLV
IEEE Organizationally Specific TLVs
Eight TLV types have been defined by the IEEE 802.1 and 802.3 working groups as a basic part of LLDP; the IEEE OUI is 00-80-C2. You
can configure the Dell EMC Networking system to advertise any or all of these TLVs.
