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.
To set a list of critical resources:
A list of profiles (default and user-created) is displayed.
The selected profile's configuration menu is displayed.
The List of Critical Resources screen displays.
Review existing CR configuration.
The screen lists the destination IP addresses or interfaces (VLAN, WWAN, or PPPoE) used for critical resource connection. IP addresses can be monitored directly by the access point or controller, whereas a VLAN, WWAN or PPPoE must be monitored behind an interface.
