These switches support application hosting in both access mode and trunk mode. Application hosting can be enabled on both modes simultaneously. Any configuration done under the app-vnic command can be rejected during activation. Note Table 1: Sample Configuration Scenarios for App Hosting in Access and Trunk Modes Application Hosting Front-Panel App Hosting on Cisco Catalyst 9300X Series Switches Scenario Supported/Unsupported Single application with two front-panel ports in access mode. Supported. No overlapping VLANs. Single application with two front-panel ports in trunk mode. Supported. No overlapping VLANs. Single application with two front-panel ports in trunk and access modes.
Supported. No overlapping VLANs. Single application with two front-panel ports in trunk mode with the default app-gateway configured. Supported. The same application with two interfaces is configured in different subnets; but the default gateway is connected to one VLAN, which has external connectivity. Single application with two front-panel ports in trunk and access modes with an overlapping VLAN. Not a valid configuration. VLAN overlapping with both ports. Single application in access mode and two front-panel ports configured on the same VLAN. Not a valid configuration. Single application in trunk mode and two front-panel ports configured on an overlapping VLAN range.
Not a valid configuration. The traffic is not isolated, and the VLAN range is overlapping. Single application in trunk mode and two front-panel ports configured on an overlapping VLAN range. Not a valid configuration. This configuration will be rejected during activation. Both the front-panel ports are in trunk mode, so any VLAN can be used. However, the same VLAN is configured for both the ports, and as a result, the VLAN overlaps with both the ports. Note The same scenario applies for access mode. Application Hosting 5
