By default, SNMP LLDP traps are disabled on all ports. The default value for the interval between SNMP LLDP trap notifications is 5 seconds.
The traps are only sent for those ports that are both enabled for LLDP and have LLDP traps enabled.

Note
If you want to send traps for LLDP MED, you must configure it separately. Use the enable snmp traps lldp-med {ports [all | port_list]} command to enable these traps.
