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…
Use the command…
Remarks
Enter system view
system-view

Required
Enable LLDP
lldp enable
Optional
By default, LLDP is enabled on
a port.
Setting LLDP Operating Mode
LLDP can operate in one of the following modes.
z
TxRx mode. A port in this mode sends and receives LLDP frames.
z
Tx mode. A port in this mode only sends LLDP frames.
z
Rx mode. A port in this mode only receives LLDP frames.
z

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…
Use the command…
