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.

IEEE Organizationally Specific TLVs

Eight TLV types have been defined by the IEEE 802.1 and 802.3 working groups
part of LLDP; the IEEE OUI is 00-80-C2. You can configure an Aggregator to advertise any or all of these
TLVs.

Description
A user-defined alphanumeric string that describes the port. FTOS does not
currently support this TLV.
A user-defined alphanumeric string that identifies the system.
A user-defined alphanumeric string that describes the system.
An optional TLV that identifies the primary functions of the system and
whether or not these primary functions are enabled; for example, repeater,
bridge, WLAN access point, router, telephone, DOCSIS cable device, end
station only).
Indicates the network address of the management interface. FTOS does not
currently support this TLV.
On Dell Force10 systems, indicates the untagged VLAN to which a port
belongs.
On Dell Force10 systems, indicates the tagged VLAN to which a port belongs
(and the untagged VLAN to which a port belongs if the port is in hybrid mode).
Indicates the user-defined alphanumeric string that identifies the VLAN.
Indicates the protocols that the port can process. FTOS does not currently
support this TLV.
