Summary:Some embodiments provide a method for preserving temporary storage values of a packet processed by a managed forwarding element (MFE. While processing a packet at the MFE, the method identifies that the packet is to be recirculated as a new packet for the MFE. A set of packet field values used for processing the packet by the MFE are associated with the packet. The method stores the set of packet field values with an identifier value. The method recirculates the packet with the identifier value attached to the packet. Upon receiving the recirculated packet, the method uses the identifier value to restore the set of packet field values for the recirculated packet.
