The historical alarm list displays all previously-active alarms in the network (or for specific NEs) over a specified time period.

Perform the following operations to manage the order and content of your alarm list:

• Filter the Merged Alarm List. Click on the Filter button to configure a filter.

• Filter the alarm list under a specific column using a quick filter. Click on the filter button in a column header, then choose an operator and enter a value in the search field at the top of a column and press Enter, or use the date picker or drop-down list (where available) and press Enter.

• Sort the alarm list under a specific column. Click on a column header to sort the list under that column. Click the column header a second time to toggle the sort order (ascending/descending), as indicated by the Up/Down arrow.

• Refresh the alarm list manually. Click the Refresh button.
