AP Critical Resources

The Critical Resources screen displays device IP addresses on the network (gateways, routers etc.). These IP addresses are critical to the health of the access point managed network. 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. Each device's VLAN, ping mode and state is displayed for the administrator.

To review a selected access point's critical resource statistics:

1. Select the Statistics menu from the Web UI.
2. Expand the System node from the navigation pane (on the left-hand side of the screen). The System node expands to display the RF Domains created within the managed network.
3. Expand an RF Domain node, select a controller or service platform, and select one of its connected access points. The access point's statistics menu displays in the right-hand side of the screen, with the Health tab selected by default.
4. Select Critical Resource from the left-hand side of the UI.
   The Statistics > AP > Critical Resource screen is displayed in the right-hand pane.
