IEEE Organizationally Specific TLVs

Eight TLV types have been defined by the IEEE 802.1 and 802.3 working groups as a basic part of LLDP; the IEEE OUI is 00-80-C2. You can configure the Dell EMC Networking system to advertise any or all of these TLVs.

Table 1. Optional TLV TypesOptional TLV Types
Type	TLV	Description
Optional TLVs
4	Port description	A user-defined alphanumeric string that describes the port. Dell EMC Networking OS 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 identifies 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. Dell EMC Networking OS does not currently support this TLV.
IEEE 802.1 Organizationally Specific TLVs
127	Port-VLAN ID	On Dell EMC Networking systems, indicates the untagged VLAN to which a port belongs.
127	Port and Protocol VLAN ID	On Dell EMC Networking 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	Protocol Identity	Indicates the protocols that the port can process. Dell EMC Networking OS 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 Dell EMC Networking OS implementation of LLDP, but is available and mandatory (non-configurable) in the LLDP-MED implementation.
127	Power via MDI	Dell EMC Networking supports the LLDP-MED protocol, which recommends that Power via MDI TLV be not implemented, and therefore Dell EMC Networking 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. Dell EMC Networking OS does not currently support this TLV.
127	Maximum Frame Size	Indicates the maximum frame size capability of the MAC and PHY.
