How it works...

There are many preconfigured policies, which will cover the majority of the day-to-day configuration changes you will need to support your infrastructure. Many of these will already be enabled, or disabled, allowing you to tweak them as needed. Not all the defaults will suit every environment. Consider CDP: we may need to turn it off on a single port, as we did before by creating an override. 

By looking at the policy, we can check that the override is working as expected.

If we click on Show Usage down in the bottom right-hand corner, we can see that the policy is being used by Leaf-1.

Clicking on Click to Show Details will show us the port that is the object of the override.
