Usage Guidelines

This command configures different actions for certain signatures. The security policy preferentially implements the action for the exception signature.

During the IPS signature database update, if the configured exception signature does not exist in the IPS signature database, the corresponding configurations are reserved but do not take effect. When the current configurations are queried, the following message is displayed: Invalid configuration. The specified signature (signature-id) does not exist in the current library. Please check and delete it.
