Hi@ster

Do not follow the global parameter when applying the CPU attack prevention template globally, that is, CPU-defend-policy hyx


After reviewing the documentation, the comment for the global parameter is: If the global parameter is specified, it means that the attack defense policy is applied to all interface boards. The real meaning is: the high-end LPU interface board has its own CPU processing unit, and the command with global is the command for these high-end boards, that is, the CPU attack prevention template is applied to the LPU board; without the global parameter, Indicates that the CPU attack prevention template is applied to the MPU of the main control board;
