In a VSX cluster, Virtual Switches are also clustered for redundancy. Virtual Switches in the cluster are defined as active/active.
By means of the ClusterXL Control Protocol (CCP), the physical interface connected to the Virtual Switch is monitored. In the event of a failover, all Virtual Systems on standby become active, and send gratuitous ARPs from the warp interface between the Virtual System and the Virtual Switch.
In the above figure, a simplified VSX cluster contains two members, one active, and the other standby. The Virtual Switches within each cluster are active/active. When the physical interface connected to either Virtual Switch fails to respond, a failover occurs.
