Performing Basic LLDP Configuration

Enabling LLDP

To make LLDP take effect on certain ports, you need to 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
Enable LLDP

Setting LLDP Operating Mode

LLDP can operate in one of the following modes.
TxRx mode. A port in this mode sends and receives LLDP frames.
Tx mode. A port in this mode only sends LLDP frames.
Rx mode. A port in this mode only receives LLDP frames.
Disable mode. A port in this mode does not send or receive LLDP frames.
Follow these steps to set LLDP operating mode:
To do...
Enter system view
Enter Ethernet interface view
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 LLDP operating mode changes on a port.
Follow these steps to set the LLDP re-initialization delay for ports:
To do...
Enter system view
Set the LLDP re-initialization
