Whenever route changes are committed, a new snapshot of the line card is taken. This snapshot includes all of the routes, their statuses and location descriptions, and their associated equipment at the time of the snapshot.
Find the line card whose history you want to review. See Viewing a Line Card.
Click the Actions button and select View Line Card History. This displays the Line Card History window.
The equipment on this form is sorted according to the sort index at the time the snapshot was taken (not necessarily the sort index that specified in the current line card type template). You can move between the changes made to the line card using the navigation bar in the lower left. The most recent snapshot is displayed when you first open this window.
