The bug has been fixed from the 7.6 and 8.0 version. But 7.6version has been deferred from the CCO and not recommended, so we may considerthe latest 8.0 version.（廠家建議升級成8.0以上的版本）

BTW:there is an Management Interface DoS Vulnerability of the7.4.121.0 version. Pls refer the blow link for details.

it’s suggest to upgrade to prevent this Vulnerability.
