Setting The Lldp Operating Mode; Setting The Lldp Re-Initialization Delay; Enabling Lldp Polling - HP 5120 EI Series Lan Switching Configuration Manual

Step
3. Enter Ethernet interface
view or port group view.
4. Enable LLDP.

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 Ethernet interface
view or port group view.
3. 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.
To set the LLDP re-initialization delay for ports:
Step
1. Enter system view.
2. Set the LLDP re-initialization
delay.

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.
