Dear friend!
There are two methods:
Method 1:
Open the ASON link list, for example, querying OTN trails:
1. Choose from the Main Menu.
2. The Filter dialog box is displayed. In this dialog box, click Filter All to display the WDM ASON Trail Management window.
3. In the trail list, right-click the WDM ASON trail that you want to view and choose from the shortcut menu.
4. In the dialog box displayed, view the basic attributes of the WDM ASON trail.
You can view the link in the ASON trail list. If the link to be queried is not in the list, it indicates that the link is not an ASON link.
Method 2:
1. The Manage WDM Trail window is displayed.
2. Check the attributes of an ASON-WDM Trail in the list. If Yes is displayed, the trail is an ASON trail. If No is displayed, the trail is a normal trail.

Thanks!
