  ./ShutInShutPend.seq [-tooloption ...] -pkt ./ShutInShutPend.def
    -tooloption : v6eval tool option

=end html =head1 PRE-TEST CONDITION Association is established between endpoint A and B. Arrange the data in endpoint B such that terminate primitive is received from ULP to terminate the association. Arrange data in endpoint A such that SHUTDOWN message is sent to endpoint B. =head1 TEST PROCEDURE Endpoint A Endpoint B ULP (ESTABLISHED) (ESTABLISHED) <---------------- DATA <--------- Terminate SHUTDOWN -----------------> (all outstanding DATA chunks have been received) <---------------- SHUTDOWN-ACK SHUTDOWN-COMPLETE -----------------> TEST DESCRIPTION: 1. Try to terminate the association between endpoint A and B by sending terminate primitive from ULP. While endpoint B is in SHUTDOWN-PENDING state, send SHUTDOWN message from endpoint A. 2. Check A: SHUTDOWN-ACK message is sent in response to the SHUTDOWN message. =head1 NOTE None =head1 REFERENCE RFC 4960 9.2. Shutdown of an Association Upon reception of the SHUTDOWN, the peer endpoint shall - enter the SHUTDOWN-RECEIVED state, - stop accepting new data from its SCTP user, and - verify, by checking the Cumulative TSN Ack field of the chunk, that all its outstanding DATA chunks have been received by the SHUTDOWN sender. Once an endpoint has reached the SHUTDOWN-RECEIVED state, it MUST NOT send a SHUTDOWN in response to a ULP request, and should discard subsequent SHUTDOWN chunks.
