Maybe I'm totally wrong but I think that LLDP advertises using a set of mandatory (not configurable) data:
Example (interface 1/A1):
switch# show lldp info local-device ethernet 1/A1
LLDP Local Port Information Detail
Port : 1/A1
PortType : local
PortId : 1
PortDesc : 1/A1
Pvid : <vlan-id>
And this is the corresponding LLDP config for that specific port (1/A1), pretty much default in this case:
switch# show lldp config ethernet 1/A1
LLDP Port Configuration Detail
Port : 1/A1
AdminStatus [Tx_Rx] : Tx_Rx
NotificationEnabled [False] : False
Med Topology Trap Enabled [False] : False
