❐Third-party vendor licenses, such as SmartFilter or Websense. If you use the restore-defaultscommand after you have installed licenses, and the serial number of your system is configurable (older boxes only), the licenses fails to install and the

SG appliance returns to the trial period (if any time is left). To correct the problem, you must configure your serial number and install your license-key again.

❐Blue Coat trusted certificates.

❐Original SSH (v1 and v2) host keys (new host keys are regenerated).

You can use the force option to restore defaults without confirmation.
