  LLDP Profile elements define settings for LLDP announcements and the type-length-values (TLVs) that the Security Engine announces.
  You can create custom LLDP Profile elements or use the default LLDP Profile element.

  In the properties of each Security Engine, you select the LLDP Profile that the Security Engine uses, and enable LLDP for individual Layer 3 Physical interfaces.
