Include the keyword for each TLV you want to advertise.
For management TLVs: system-capabilities, system-description.
For 802.1 TLVs: port-protocol-vlan-id, port-vlan-id .
For 802.3 TLVs: max-frame-size.
For TIA-1057 TLVs:

In the following example, LLDP is enabled globally. R1 and R2 are transmitting periodic LLDPDUs that contain management, 802.1, and
802.3 TLVs.

Storing and Viewing Unrecognized LLDP TLVs
Dell EMC Networking OS provides support to store unrecognized (reserved and organizational specific) LLDP TLVs. Also, support is
extended to retrieve the stored unrecognized TLVs using SNMP.
When the incoming TLV from LLDP neighbors is not recognized, the TLV is categorized as unrecognized TLV. The unrecognized TLVs is
categorized into two types:
1. Reserved unrecognized LLDP TLV
2. Organizational specific unrecognized LLDP TLV
Reserved Unrecognized LLDP TLVs
The type value for reserved TLV ranging from 9 to 126.
The system processes each LLDP frame to retrieve the type and length, and stores the retrieved data of reserved unrecognized LLDP
TLVs in a list. The stored list of unrecognized TLVs is removed when subsequent LLDP neighbor frame is received, neighbor is lost, or
neighbor ages out. If there are multiple unrecognized TLVs with the same TLV type, only the information of first unrecognized TLV is
stored and the TLV discard counter is incremented for the successive TLVs.
