Critical resources are device IP addresses or interface destinations on the network defined as critical to the health of the controller, service platform or access point managed network. The critical resource feature allows for the continuous monitoring of these addresses. A critical resource, if not available, can result in the network suffering performance degradation. A critical resource can be a gateway, AAA server, WAN interface or any hardware or service on which the stability of the network depends. Critical resources are pinged regularly. If there's a connectivity issue, an event is generated stating a critical resource is unavailable. By default, there's no enabled critical resource policy and one needs to be created and implemented.
Critical resources can be monitored directly through the interfaces on which they're discovered. For example, a critical resource on the same subnet as an AP 8132 access point can be monitored by its IP address. However, a critical resource located on a VLAN must continue to monitored on that VLAN.
Critical resources can be configured for controllers, service platforms and access points using their respective device model profiles.
