About Logical Devices
A logical device lets you run one application instance (either ASA or threat defense) and also one optional decorator application (Radware DefensePro) to form a service chain.
When you add a logical device, you also define the application instance type and version, assign interfaces, and configure bootstrap settings that are pushed to the application configuration.
Note | For the Firepower 9300, you can install different application types (ASA and threat defense) on separate modules in the chassis. You can also run different versions of an application instance type on separate modules. |
