Setting LLDP Operating Mode
LLDP can operate in one of the following modes.
z
TxRx mode. A port in this mode sends and receives LLDPDUs.
z
Tx mode. A port in this mode only sends LLDPDUs.
z
Rx mode. A port in this mode only receives LLDPDUs.
z
Disable mode. A port in this mode does not send or receive LLDPDUs.
Follow these steps to set LLDP operating mode:

| 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:

2 seconds by default
Enable LLDP Polling
With LLDP polling enabled, a device checks for the local configuration changes periodically. Upon
detecting a configuration change, the device sends LLDPDUs to inform the neighboring devices of the
change.
