Optional Tlvs; Management Tlvs - Dell Force10 C150 Configuration Manual

Optional TLVs

FTOS supports the following optional TLVs:
Management
•
• IEEE 802.1 and 802.3 Organizationally Specific TLVs
• 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. The five types are described in
Organizationally Specific TLVs
Organizationally specific TLVs can be defined by a professional organization or a vendor. They have two
mandatory fields
• Organizationally Unique Identifier (OUI)—a unique number assigned by the IEEE to an organization
or vendor.
• OUI Sub-type—These sub-types indicate the kind of information in the following data field. The
sub-types are determined by the owner of the OUI.
