validation succeeds. A configuration in progress may be validated in this way at any time without
affecting an active firewall configuration.
3. After ‘fw1’ has been verified, it may be made active in the system by setting the active-config variable
to the name: ‘fw1’, setting firewall-enable and committing the changes. The system validates the
active firewall configuration and if it finds no errors, it activates the ‘fw1’ firewall configuration.
4. While the ‘fw1’ firewall configuration is active, you might wish to make changes without altering
the live configuration. Using the CLI, copy the firewall configuration named ‘fw1’ to ‘fw2’. Change
the work-config variable to ‘fw2’. Any configuration changes made to ‘fw2’ are validated when you
commit your changes, and any errors in ‘fw2’ are displayed. An alternate configuration may be
modified and validated in this way at any time without affecting an active firewall configuration.
5. Alternatively, while the ‘fw1’ firewall configuration is active, you might wish to make changes to the
live configuration. Any changes made to a configuration that is defined as ‘active-config’ and ‘enable’
will be reflected on the live configuration currently running on the system, pending a successful
validation. For instance, work-config can be a configuration named ‘fw2’ while active-config is
‘fw1’ and enabled. Modifying fw1 in this case will, upon successful validation, update the running
configuration to reflect the changes.
