This section describes VSX High Availability features. In a VSX environment, you can work with one of two High Availability scenarios:
VSX Gateway High Availability: Each cluster member functions as a VSX Gateway and is synchronized with the other members. If one member goes down, it immediately fails over to another member. Likewise, if an individual Virtual System, Virtual Router or Virtual Switch goes down, the entire member fails over to another member. All members and Virtual Systems function in an active/active mode and are continuously synchronized.

VSX Gateway High Availability is the default cluster configuration. All members of a cluster must be configured to use the same clustering mode.
In the above example, member M1 experiences a failure the affects VS1 and all Virtual Systems immediately fail over to member M2.
