This SnmpAdminString object, delivered alongside the cvsDualActiveDetectionNotif trap, describes the cause of the dual-active condition and which detection method caught it. Because a dual-active event in a virtual switch can cause both chassis to forward traffic independently and create loops or duplicate MAC conflicts, this text gives the admin the specific mechanism (e.g., which detection protocol fired) needed to diagnose the failure quickly. When the trap arrives, an on-call engineer would read this field to learn whether it was, for instance, a Fast Hello or PAgP-based dual-active detection method that triggered the alert.
