Step 4. Enable LLDP. Command lldp enable Remarks Optional. By default, LLDP is enabled on a port. 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. To set the LLDP operating mode: Step 1. Enter system view. 2. Enter Layer 2 Ethernet interface view. 3. Set the LLDP operating mode. Command system-view interface interface-type interface-number lldp admin-status { disable | rx | tx | txrx } Remarks N/A N/A 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 changes to the LLDP operating mode on a port. To set the LLDP re-initialization delay for ports: Step 1. Enter system view. 2. Set the LLDP re-initialization delay. Command system-view lldp timer reinit-delay delay Remarks N/A Optional. 2 seconds by default. Enabling LLDP polling With LLDP polling enabled, a device periodically searches for local configuration changes. On detecting a configuration change, the device sends LLDPDUs to inform neighboring devices of the change. To enable LLDP polling: Step 1. Enter system view. Command system-view Remarks N/A 200

Optional.
By default, LLDP is enabled on
a port.
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.
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.

Enabling LLDP polling
With LLDP polling enabled, a device periodically searches for local configuration changes. On detecting
a configuration change, the device sends LLDPDUs to inform neighboring devices of the change.
