Application Hosting on Cisco Catalyst 9400 Series Switches This section describes application-hosting on Cisco Catalyst 9400 Series Switches. Cisco Catalyst 9400 Series Switches support the management interface and front-panel ports for application hosting. Applications can be hosted on C9400-SSD-240GB, C9400-SSD-480GB, and C9400-SSD-960GB solid state drives (SSDs). These switches use the M2 SATA module for application hosting. For more information, see the "M2 SATA Module" chapter in the Interfaces and Hardware Configuration Guide .
Application Hosting Application Hosting on Cisco Catalyst 9400 Series Switches Stack Mode Apps Ports Used Behavior Cisco Catalyst 9300X Series Switch active + Cisco Catalyst 9300 Series Switch standby 1 2 Not supported. In this scenario, when a switchover happens, the new active will not have two front-panel ports, and the app configuration fails. After the switchover, the application is not restarted on Cisco Catalyst 9300 Series Switch, because only one front-panel port is configured, and this configuration fails. The application must be reconfigured using the available front-panel port.
Cisco Catalyst 9300X Series Switch active + Cisco Catalyst 9300 Series Switch standby 2 2 Not supported. Note Two applications, for example, app1 and app2 are running, with each application using a different front-panel port, for example, port1 and port2 respectively. After a switchover, app1 on front-panel port1 starts on Cisco Catalyst 9300 Series Switch in a running state. However, app2 is not started on Cisco Catalyst 9300 Series Switch as there is no front-panel port2. Catalyst 9300 Series Switch active + Catalyst 9300X Series Switch standby 1 or more 1 Supported. Note After a switchover, the application is restarted on Catalyst 9300X Series Switch using the front-panel port.
