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
