FTOS Configuration Guide for the C-Series - Force10 Networks

Organizationally Specific TLVs
Organizationally specific TLVs can be defined by a professional organization or a vendor. They have two
mandatory fields (Figure 187) in addition to the basic TLV fields (Figure 185):
• 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 (Table 23) as a basic part
of LLDP; the IEEE OUI is 00-80-C2. You can configure the Force10 system to advertise any or all of these
TLVs.

TLV Length
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.

127 Port-VLAN ID On Force10 systems, indicates the untagged VLAN to which a port
belongs
127 Port and Protocol VLAN ID On 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)
127 VLAN Name Indicates the user-defined alphanumeric string that identifies the VLAN.
This TLV is supported on C-Series only.
127 Protocol Identity Indicates the protocols that the port can process. FTOS does not
currently support this TLV.
