I have two unix machines which are dual homed. One of them is running echo

tool and the other is running my 'monitor cum terminal' program. After the
>
association have been established, I pulled out one of the cables to

simulate a Network status change. From my program, I found out that after a

Network status change event has been called, the state of the path which
>
has gone inactive remains 0 (SCTP_PATH_ACTIVE) instead of being changed to
>
1(SCTP_PATH_INACTIVE).

Also, when I made the primary path inactive, the SCTP library did not
>
assign the next active path as the primary path like it did in Pre 9
>
release. Instead, the terminal program still tries to send sctp packets
>
thru the primary path (which has gone inactive) after a networkstatus
>
changed has been registered. As a results, the packets are only sent via
>
the active path after a number of attempts to send it on the primary path
>
(now inactive) has failed.
>
I did not have this problem when I was working in Pre 9. I only experienced
>
this after upgrading to pre 11 and above. I don't know if this is a bug or
>
I have done something wrong. Could you guys pls verify that?

Best regards,
