High Availability Configuration  41
High Availability Configuration
An HA port allows you to cable two devices together and configure them to work as
a redundant group. A redundant group consists of one primary device and one
backup device. If the primary device fails, the backup device takes over as the new
primary, thus avoiding interruption of services.
This section describes how to connect your device for high availability.
Figure 23: HA Cabling Connections
NOTE: Do not mix port interface types. HA configuration is not supported on WAN
interfaces. You must have the same hardware configuration for both devices for
HA to work correctly. For more information about HA configuration, refer to the
Concepts & Examples ScreenOS Reference Guide.
