I do not see anything wrong here. The S1 link is setup correctly between the eNB and corenet : the connection is successful here. There are 2 reset messages then in the pcap, listing 2 UE contexts ; however, there was no UE context setup before. Moreover, the reset message causes are both "eutran-generated". You should review your eNodeB and corenet configuration. On my side, I see no failure here.

But eNodeB don't receive Reset acknowledge message.

Yes, the S1AP Reset procedure is not implemented in libmich (it should land here, if implemented: https://github.com/mitshell/libmich/blob/master/libmich/mobnet/UES1proc.py).

Note that I am not developing libmich anymore ; therefore, if you want it to support the S1AP Reset procedure, you will have to find your own way (sorry for this rude answer, but time is missing on my side). Pycrate (a replacement for libmich) will have support for 4G S1AP interfaces in some monthes. It already has 3G Iuh interface's support.

Finally, I do not also fully understand what you are expecting from corenet. This S1AP Reset procedure seems not required to support LTE UE attachment and connection. What should I understand by "fail connect with e-40 ip.access" ?
