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:

Enabling LLDP Polling
With LLDP polling enabled, a device checks for local configuration changes periodically. Upon detecting
a configuration change, the device sends LLDP frames to inform the neighboring devices of the change.
