To configure a new Wireless Access Point Over subscription threshold:

1. Configure the following:
   • Name. Specify a name for the threshold. This name helps you identify the threshold in the Threshold library and displays as the report title on the Alert Center Home page.
   • Threshold. Select and enter the desired threshold criteria variables and values. The default threshold is configured to alert when the average number of clients attached exceeds the 'Client Count' for more than the specified 'Time Range'.
   • Devices to Monitor. Click Select to choose the devices to which the threshold applies. The Threshold Devices dialog appears. Specify to which devices the threshold applies by adding them or to which devices the threshold does not apply by excluding them using this dialog. Additionally, groups can also be added or excluded from the threshold using this dialog. Click OK.
   • Notification. Select the notification policy to apply to this threshold. This policy begins sending notifications when an item is outside the configured threshold limits. If you do not see an appropriate threshold policy, or if the list is empty, click browse (...) to open the Notification Policy dialog and configure a new policy.

   Note: Notification policies are optional for most thresholds. If you do not select a notification policy, no notifications are generated for the threshold, but a dashboard report listing the out of threshold items still appears on the Alert Center Home page.

   • Threshold check. Enter a value for the threshold check interval, or the interval at which the Alert Center checks the Network Performance Monitor database to see if there are items that are out of the threshold's parameters. The default check interval is every 10 minutes.
   • Select Automatically resolve items no longer out of threshold to have Alert Center automatically resolve items when they go back inside the parameters of the threshold.
2. Click OK.

Clone a threshold based on a custom or built-in configuration:

1. Click on a threshold on the Thresholds Library panel you want to copy.
2. Click the Copy button, and click OK to create a new Device Over Subscription Threshold.

   The Edit Device Over Subscription Threshold dialog displays.

3. Save or customize your new threshold, either:
   • Type in a new value for Name field (or keep the default) and click OK to save to the Thresholds Library.
   • Follow the Edit Device Over Subscription Threshold instructions.

Delete an existing Device Over Subscription Threshold:

1. Select Device Over Subscription Threshold you want to delete from the Device Over Subscription Threshold panel.
2. Click the Delete button, and then click Yes to confirm the deletion.

   The Device Over Subscription Threshold configuration is deleted.
