Beginning in IDP OS Release 5.1, you can operate the IDP Series device in simulation mode. In
simulation mode, the original packets are forwarded immediately and the IDP Series device
processes a copy, logging actions that would have been taken if simulation mode were not
enabled.
You operate an IDP Series device in simulation mode in the following situations:
When you first deploy the IDP Series device in your network and you want to evaluate the
security actions it takes without disrupting traffic.
When you implement a new feature or change a security policy and you want to evaluate the
impact without disrupting traffic.
As a workaround to avoid traffic outages when IDP processing is resulting in crashes and other
failures.
