This is the current SCTP state machine position for this specific association (closed, cookieWait, cookieEchoed, established, and the various shutdown states), and per the MIB the only value a management station is permitted to write here is deleteTCB, which forcibly tears down the association's control block, analogous to TCP's deleteTCB mechanism. An engineer would use a SET to deleteTCB to forcibly kill a stuck or hung association that isn't tearing down cleanly on its own, without needing to reboot the device or restart the application. Seeing an association stuck in cookieWait for an extended period, rather than progressing to established, points to the handshake failing to complete, likely due to the peer not responding to the INIT.
