Optional TLVs

The Dell Networking OS supports these optional TLVs: management TLVs, IEEE 802.1 and 802.3 organizationally specific TLVs, and

TIA-1057 organizationally specific 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.
