Listing Modified Configuration Objects - D-Link NetDefendOS User Manual

After modifying several configuration objects, you might want to see a list of the objects that
were changed, added and removed since the last commit.
Example 2.17. Listing Modified Configuration Objects
This example shows how to list configuration objects that have been modified.
Command-Line Interface
gw-world:/> show -changes
Type

A "+" character in front of the row indicates that the object has been added. A "*" character
indicates that the object has been modified. A "-" character indicates that the object has been
marked for deletion.
Web Interface

Activating and Committing a Configuration
After changes to a configuration have been made, the configuration has to be activated for those
changes to have an impact on the running system. During the activation process, the new
proposed configuration is validated and NetDefendOS will attempt to initialize affected
subsystems with the new configuration data.
Important: Committing IPsec Changes
The administrator should be aware that if any changes that affect the configurations of
live IPsec tunnels are committed, then those live tunnels connections will be terminated
and must be re-established.
If the new configuration is validated, NetDefendOS will wait for a short period (30 seconds by
default) during which a connection to the administrator must be re-established. As described
previously, if the configuration was activated via the CLI with the activate command then a
commit command must be issued within that period. If a lost connection could not be
re-established or if the commit command was not issued, then NetDefendOS will revert to using
the previous configuration. This is a fail-safe mechanism and, amongst others things, can help
prevent a remote administrator from locking themselves out.
