Description
Use ha slave-ignore-version-check to ignore version check of the standby MPU, meaning not to check
whether the version of the standby MPU is consistent with that of the active MPU.
Use undo ha slave-ignore-version-check to enable version check of the standby MPU.
By default, version check of the standby MPU is enabled.
Inconsistency of the software version of the active MPU and standby MPU might result in system failure
when the system is running.
