3.
Set the LLDP operating mode. lldp admin-status { disable | rx | tx |
txrx }
Optional.
The default setting is TxRx.
Setting the LLDP re-initialization delay
When the LLDP operating mode changes on a port, the port initializes the protocol state machines after
an LLDP reinitialization delay. By adjusting the delay, you can avoid frequent initializations caused by
frequent changes to the LLDP operating mode on a port.
To set the LLDP reinitialization delay for ports:

lldp timer reinit-delay delay
Optional.
The default setting is 2 seconds.
Enabling LLDP polling
With LLDP polling enabled, the switch periodically searches for local configuration changes. When the
device detects a configuration change, it sends LLDP frames to inform neighboring switches of the
change.
To enable LLDP polling on the specified port or ports:
