This read-write TruthValue object turns the generation of the cvsDualActiveDetectionNotif SNMP notification on or off. Dual-active detection is critical in a virtual switch because if the VSL link fails, both chassis may believe they are the sole active switch, causing network conflicts; this trap alerts operators the moment that condition is caught. An admin managing a VSS pair would enable this object so their monitoring system pages someone immediately if a dual-active event occurs rather than discovering it later through network instability.
