Advertising TLVs
You can configure the system to advertise TLVs out of all interfaces or out of specific interfaces.
• If you configure the system globally, all interfaces send LLDPDUs with the specified TLVs.
• If you configure an interface, only the interface sends LLDPDUs with the specified TLVs.
• If you configure LLDP both globally and at interface level, the interface level configuration overrides the
global configuration.
To advertise TLVs, use the following commands.
1 Enter LLDP mode.
CONFIGURATION or INTERFACE mode
protocol lldp
2 Advertise one or more TLVs.
PROTOCOL LLDP mode
advertise {management-tlv | dot1-tlv | dot3-tlv | med}
