IEEE Organizationally Specific TLVs
Eight TLV types have been defined by the IEEE 802.1 and 802.3 working groups (Table 30-2) 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 30-2. Optional TLV Types
Type 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 On Dell Force10 systems, indicates the untagged VLAN to which a port
belongs
127 Port and Protocol VLAN ID 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)
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.
IEEE 802.3 Organizationally Specific TLVs
127 MAC/PHY Configuration/Status Indicates the capability and current setting of the duplex status and bit rate, and
whether the current settings are the result of auto-negotiation. This TLV is not
available in the FTOS implementation of LLDP, but is available and mandatory
(non-configurable) in the LLDP-MED implementation.
127 Power via MDI Dell Force10 supports LLDP-MED protocol, which recommends that Power
via MDI TLV be not implemented, and therefore Dell Force10 implements
Extended Power via MDI TLV only.
127 Link Aggregation Indicates whether the link is capable of being aggregated, whether it is currently
in a LAG, and the port identification of the LAG. FTOS does not currently
support this TLV.
127 Maximum Frame Size Indicates the maximum frame size capability of the MAC and PHY
