Organizationally Specific TLVs Organizationally specific TLVs can be defined by a professional organization or a vendor. They have two mandatory fields (Figure 29-3) in addition to the basic TLV fields (Figure 29-1): • 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. Figure 29-3. Organizationally Specific TLV TLV Type (127) 7 bits TLV Length Organizationally Organizationally Unique ID Defined Sub-type (OUI) Organizationally Specific Data 9 bits 3 octets 1 octet 0 - 507 octets fnC0052mp IEEE Organizationally Specific TLVs Eight TLV types have been defined by the IEEE 802.1 and 802.3 working groups (Table 29-2, "Optional TLV Types," in Link Layer Discovery Protocol) as a basic part of LLDP; the IEEE OUI is 00-80-C2. You can configure the Dell Force10 system to advertise any or all of these TLVs. Table 29-2. Optional TLV Types Typ e TLV Description Optional TLVs 4 Port description A user-defined alphanumeric string that describes the port. FTOS does not currently support this TLV. 5 System name A user-defined alphanumeric string that identifies the system. 6 System description A user-defined alphanumeric string that describes the system 7 System capabilities Identifies the chassis as one or more of the following: repeater, bridge, WLAN Access Point, Router, Telephone, DOCSIS cable device, end station only, or other 8 Management address Indicates the network address of the management interface. FTOS does not currently support this TLV. IEEE 802.1 Organizationally Specific TLVs 127 Port-VLAN ID 127 Port and Protocol VLAN ID 127 VLAN Name 127 Protocol Identity 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. This TLV is supported on C-Series only. Indicates the protocols that the port can process. FTOS does not currently support this TLV. Link Layer Discovery Protocol | 567
