Performing basic LLDP configuration
Enabling LLDP
To make LLDP take effect on specific ports, you must enable LLDP both globally and on these ports.
Follow these steps to enable LLDP:
To do...
Enter system view
Enable LLDP globally
Enter Ethernet
interface view
or port group
view
Enable LLDP
Setting the LLDP operating mode
LLDP can operate in one of the following modes.
TxRx mode—A port in this mode sends and receives LLDPDUs.
•
Tx mode—A port in this mode only sends LLDPDUs.
•
Rx mode—A port in this mode only receives LLDPDUs.
•
Disable mode—A port in this mode does not send or receive LLDPDUs.
•
Follow these steps to set the LLDP operating mode:
To do...
Enter system view
Enter Ethernet
interface view
or port group

Set the LLDP operating mode
Setting the LLDP re-initialization delay
When LLDP operating mode changes on a port, the port initializes the protocol state machines after a
certain delay. By adjusting the LLDP re-initialization delay, you can avoid frequent initializations caused
by frequent changes to the LLDP operating mode on a port.
Follow these steps to set the LLDP re-initialization delay for ports:
