Param_addressfamily: The address family to specify the table against which the reservation processing has to be performed.

Param_reservationId: This is the RecordId of the DHCP reservation to be modified. If this is not specified, a new reservation row will be created.

Param_addressId: This is the RecordId of the IPAM IP address in ADM_IPAddressTable to which the reservation is associated with.

The procedure returns the following as the output parameter.

  3. Set ScopeRecordId of the row to Param_scopeId.

  4. Set IPAddressRecordId of the row to Param_addressId.

  5. Copy Param_reservationDetails to ReservationDetails of the row.

  6. Update/insert the row into the table.

  7. If the new row has been added, assign RecordId to Result_reservationId. Otherwise assign Param_reservationId to Result_reservationId.
