Exclude interface health monitoring

Use interface exclusion when you want to suppress health status updates for selected physical interfaces without suppressing health monitoring for the entire device. Interface exclusion is useful when interface state is expected during maintenance or when you want to focus on subinterface health instead of physical interface status.

When you configure interface exclusion, select the physical interfaces that you want to exclude from the list of available interfaces. Depending on the available UI options in your version, selecting a physical interface can also exclude its subinterfaces. If subinterface controls are available, you can continue monitoring subinterfaces while excluding only the physical interface.

Use this option to reduce unnecessary health alerts when traffic loss or interface state changes are expected on a physical interface.
