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:

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:
