Figure 22. Discard changes confirmation pop-upIf invalid or incomplete settings have been specified for at least
one parameter, the button will be shown greyed out
and disabled until such settings have been corrected.
Any change made in the page will become effective only after
the APPLY button has been clicked.
Conversely, modifications can be discarded by leaving the page
without clicking APPLY: in that case, a pop-up windows will be
displayed asking to confirm this action, contextually offering the
possibility of reenter the configuration page (see Figure 22).
Some configuration changes require the router to be rebooted:
in this case, a warning page will pop-up (See Figure 23) notify-
ing the need for such action and asking for a confirmation to
proceed.
During reboot a progress bar will be shown with the indication
of the approximate time remaining for completing the operation
(see Figure 24).
When reboot terminates, a notification is issued and the user is
redirected to home page and requested to login again.
