Advertising TLVs
You can congure the system to advertise TLVs out of all interfaces or out of specic interfaces.
• If you congure the system globally, all interfaces send LLDPDUs with the specied TLVs.
• If you congure an interface, only the interface sends LLDPDUs with the specied TLVs.
• If you congure LLDP both globally and at interface level, the interface level conguration overrides the global conguration.
