closed(1), listen(2), synSent(3), synReceived(4), established(5), finWait1(6), finWait2(7), closeWait(8), lastAck(9), closing(10), timeWait(11), deleteTCB(12) |
TCP connection state. The only value that a management station can set is deleteTCB(12). If a management station tries to set the object to a value other than deleteTCB(12), the agent will return an error response. If the object value is set to deleteTCB(12), TCB will be deleted and the corresponding TCP connection will be terminated. |
