Critical resources are device IP addresses or interface destinations on the network interoperated
as critical to the health of the 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, a AAA server, a WAN
interface or any hardware or service on which the stability of the network depends. Critical
resources are pinged regularly by the access point. 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 the 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 access points and wireless controllers using their
respective profiles.
To define critical resources:
1. Select the Configuration tab from the Web UI.
2. Select Devices.
3. Select System Profile from the options on left-hand side of the UI.
4. Select Critical Resources.
FIGURE 89
Critical Resources screen - List of Critical Resources tab
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.
5. Select the Add button at the bottom of the screen to add a new critical resource and
connection method, or select and existing resource and select Edit to update the resource’s
configuration.
