Sensors

A security policy can be applied at the Sensor level; however, this policy application is intended to be inherited by those interfaces of a Sensor whose custom-applied policy has been deleted. For example, you have created a custom IPS policy called Custom1. You apply it to interfaces G2/3, G3/1, and G3/4 on a single NS7200 Sensor. After some time, you determine Custom1 does not work effectively, and you want to delete it. You can apply a different policy to the Sensor that will allow you to delete the custom policy without having to change the policy at each interface where it has been applied. When you delete the custom policy, all of the interfaces (G2/3, G3/1, and G3/4) enforcing the policy will inherit the policy applied to the Sensor.
