Virtual Switches in a High Availability VSX Cluster
In a VSX Cluster, Virtual Switches are also clustered for redundancy and are defined as Active/Active.
The physical interface connected to the Virtual Switch
Virtual Device on a VSX Gateway or VSX Cluster Member that functions as a physical switch. Acronym: VSW. is monitored by means of the Cluster Control Protocol (CCP).
In the event of a failover, all Virtual Systems on the Standby VSX Cluster Member Security Gateway that is part of a cluster. become Active, and send Gratuitous ARP Requests from the warp interface between the Virtual System Virtual Device on a VSX Gateway or VSX Cluster Member that implements the functionality of a Security Gateway. Acronym: VS. and the Virtual Switch.

In the above figure, a simplified VSX Cluster contains two VSX Cluster Members in the High Availability mode, one Active, and the other Standby.
The Virtual Switches within each VSX Cluster are Active/Active.
When the physical interface connected to either Virtual Switch fails to respond, a failover occurs.
