Hi friend!
By default, the initial password change notification function is enabled on the S5720.
To disable this function, run the undo command.
<HUAWEI> system-view
[HUAWEI] aaa
[HUAWEI-aaa] local-aaa-user password policy administrator
[HUAWEI-aaa-lupp-admin] undo password alert original
Note: The initial password includes the default password of the device, the password set by a local user for the first time, and the password changed by a non-local user. For example, if user B changes the password of user A, the device displays a message when user A logs in to the device using the new password.
Hope to help you!
