Both small and large enterprise campuses require a highly available and secure, intelligent network infrastructure to support business solutions such as voice, video, wireless, and mission-critical data applications. To provide such a reliable network infrastructure, the overall system of components that make up the campus must minimize disruptions caused by component failures. Understanding how the system recovers from component outages (planned and failures) and what the expected behavior is during such an outage is a critical step in designing, upgrading, and operating a highly available, secure campus network.
