You view the impacts for an MPLS problem notification by clicking the Impact tab in the Notification Properties dialog box. The Impact tab lists all of the affected objects for the notification.
For example, Impact tab that shows the impacts for the VRF Down problem lists the impacts that are diagnosed by MPLS Manager for the VRF Down problem shown in GUID-655CDD38-ACB0-4F2E-BA23-B9A874DD53E1.html#GUID-655CDD38-ACB0-4F2E-BA23-B9A874DD53E1___MPLS_USER_MAPS_97101.
For an MPLS impact notification, that is, a notification that identifies an MPLS object that is impacted by a problem, a Caused By tab (instead of the Impact tab) appears in the Notifications Properties dialog box. Caused By tab that shows the problems causing a VPN Impacted impact provides an example. The Caused By tab lists the problems that caused the notification.
