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:

Enable LLDP globally
lldp enable
Required
By default, LLDP is globally disabled.

Required
Use either command.
Enable LLDP
lldp enable
Optional
By default, LLDP is enabled on a port.
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:

Optional
TxRx by default.
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:
