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 
— 
Enable LLDP globally 
lldp enable 
Required 
By default, LLDP is disabled 
globally. 
Enter Ethernet interface view 
interface interface-type 
interface-number 
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  Disable mode. A port in this mode does not send or receive LLDP frames. 
Follow these steps to set LLDP operating mode: 
To do…  Use the command…  Remarks 
Enter system view

Required
 
Set the LLDP operating mode 
lldp admin-status { disable | 
rx | tx | txrx } 
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 LLDP operating mode changes on a port.  
Follow these steps to set the LLDP re-initialization delay for ports: 
To do…  Use the command…  Remarks 
Enter system view

— 
Set the LLDP re-initialization 
delay 
lldp timer reinit-delay delay 
Optional 
2 seconds by default
