=end html =head1 PRE-TEST CONDITION Association is not established between endpoint A and B. Arrange the data in endpoint A such that COOKIE-ACK is sent to endpoint B. =head1 TEST PROCEDURE Endpoint A Endpoint B ULP (CLOSED) (CLOSED) COOKIE-ACK ----------------> Silently discard TEST DESCRIPTION: 1. Send COOKIE-ACK message from endpoint A to B, when there is no association between them. 2. Check A: COOKIE-ACK message will be silently discarded. 3. Check B: State of endpoint B is not disturbed. =head1 NOTE None =head1 REFERENCE RFC 4960 8.4.

    7)  If the packet contains a "Stale Cookie" ERROR or a COOKIE ACK,
        the SCTP packet should be silently discarded.  Otherwise,
=end html 8) The receiver should respond to the sender of the OOTB packet with an ABORT. When sending the ABORT, the receiver of the OOTB packet MUST fill in the Verification Tag field of the outbound packet with the value found in the Verification Tag field of the OOTB packet and set the T bit in the Chunk Flags to indicate that the Verification Tag is reflected. After sending this ABORT, the receiver of the OOTB packet shall discard the OOTB packet and take no further action.
