Using the Commit Options to Commit Configuration Changes (J-Web Procedure)
You can use the single-commit feature to commit all outstanding configuration changes
in the J-Web interface on EX Series switches simultaneously. This helps in reducing the
time J-Web takes for committing configurations because when changes are committed
at every step, rollback configurations pile up.
For example, suppose you want to delete a firewall filter and add a new one. With
immediate commits, you would need to commit your changes twice for this action. Using
single commit, you can decrease the number of commits to one, thus saving time for
working on other configurations.
When you edit a configuration, you work on a copy of the current configuration, which is
your candidate configuration. The changes you make to the candidate configuration are
visible through the user interface immediately, allowing other users to edit those
configurations, but they do not take effect on the switch until you commit the changes.
When you commit the configuration, the candidate file is checked for proper syntax,
activated, and marked as the current, operational software configuration file. If multiple
users are editing the configuration when you commit the candidate configuration, changes
made by all users take effect.
You can configure the commit options to either commit all configuration changes together
or commit each configuration change immediately using the J-Web Commit Preference
page.
NOTE: There are some pages on which configuration changes must be
committed immediately. For such pages, if you configure the commit options
for a single commit, the system displays warning notifications that remind
you to commit your changes immediately. An example of such a page is the
Interface Page (Configure > Interface).
To configure the commit options on an EX Series switch using the J-Web interface:
1. Select Commit Options.
NOTE: All action links except Preference are disabled unless you edit, add,
or delete a configuration.
