To enable LLDP to be compatible with CDP on the port, 
you must enable CDP compatibility on the Global Setup 
tab and set the CDP operating mode on the port to TxRx. 
LLDP Polling Interval
Enable LLDP polling and set the polling interval.  
If no polling interval is set, LLDP polling is disabled.  
With the polling mechanism, LLDP periodically detects 
local configuration changes. If a configuration change is 
detected, an LLDPDU is sent to inform the LLDP 
neighbors of the change.  
LLDP Trapping  
Set the enable status of the LLDP trapping function on the 
port or ports.  
LLDP trapping is used to report to the network 
management station critical events such as new neighbor 
devices detected and link failures. 
 
To avoid excessive traps from being sent when topology is 
instable, you can tune the minimum trap transit interval on 
the Global Setup tab.
