For Network IPS appliances, set the ignore response to configure the appliance to disregard packets that match criteria that are specified within a security event or a response filter.
If you select the ignore response when you create response filters or security events, the appliance does not act when it detects the matching packets. You use the ignore response to filter security events that do not threaten your network. For more information, see Configuring security event options and Configuring response filters.
