APAR status

• Closed as program error.

Error description

• When doing Interface level polling (e.g. SNMP Link State) , we
  don't raise alerts on unmanaged Interfaces, but it still raise
  event on sub-interfaces. They should be suppressed too as the
  parent is in unmanaged state. Like we do Chassis level i.e. when
  Chassis in unmanaged, all Interfaces are implicitly in unmanaged
  state too.
  
  The issue can be fixed in the discovery by adding a stitcher to
  set sub-interfaces as unmanaged if the owning interface is
  unmanaged.

Problem conclusion

• Enhanced a new option in disco.config to have sub interfaces
  unmanaged if primary interface is unmanaged in
  TagManagedEntities.stch (3.9) or
  PopulateDNCIM_ManagedStatus.stch.
  
  New option added for disco.config table in DiscoConfig.cfg
  (defined in DiscoSchema.cfg):
  
      m_UnmanagedSubInts int type boolean     // Should we set
  sub-interfaces as
  
  // unmanaged when the owning specific
  
  // types of interface is unmanaged?
  
  Specifies whether to automatically set sub-interfaces as
  unmanaged when the owning specific interface is marked as
  unmanaged by TagManagedEntities.stch (3.9 FP5 and later
  releases) or PopulateDNCIM_ManagedStatus.stch (4.1.1 FP1 and
  later releases) :
    0: Default, do not automatically set unmanaged for
  sub-interfaces.
    1: Automatically set unmanaged for sub-interfaces if the owing
  interface is set to unmanaged by the stitcher.
