Hi friend!
In two-phase validation mode, check whether the commit command has been executed.
After running configuration commands in two-phase validation mode, you must run the commit command to commit configurations. The commit status of configurations can be queried using configuration query commands. You can refer to the link https://info.support.huawei.com/network/ptmngsys/Web/tsrev_ne/en/content/ne/10_edesk_vrp_new_or_modified_configuration_cannot_take_effect_v8/edesk_vrp_new_or_modified_configuration_cannot_take_effect_v8_edesk002.html
Hope to help you!
