10 Limitations and restrictions of Virtual Fabrics Virtual Fabrics interaction with other Fabric OS features Table 51 lists some Fabric OS features and considerations that apply when using Virtual Fabrics. TABLE 51 Virtual Fabrics interaction with Fabric OS features Fabric OS feature Virtual Fabrics interaction Access Gateway Virtual Fabrics is not supported on a switch if AG mode is enabled. Admin Domains Virtual Fabrics and Admin Domains are mutually exclusive and are not supported at the same time on a switch. To use Admin Domains, you must first disable Virtual Fabrics; to use Virtual Fabrics, you must first delete all Admin Domains. Refer to "Deleting all user-defined Admin Domains non-disruptively" on page 450 for information on deleting Admin Domains without disrupting device-to-device communication. Configuration upload and download Virtual Fabrics uses a configuration file that is different from the configuration file used to download system configuration parameters. Refer to Chapter 8, "Maintaining the Switch Configuration File," for more information about how Virtual Fabrics affects the configuration file. Encryption Encryption functionality using the FS8-18 blade is available only on the default logical switch. FC-FC Routing Service All EX_Ports must reside in a base switch. You cannot attach EX_Ports to a logical switch that has XISL use enabled. You must use ISLs to connect the logical switches in an edge fabric. Refer to Chapter 24, "Using FC-FC Routing to Connect Fabrics," for more information about Virtual Fabrics and FC-FC routing. FICON Up to two logical switches per chassis can run FICON Management Server (CUP), but the FICON logical switch can use both ISLs and XISLs. Licensing Licenses are applicable for all logical switches in a chassis. Performance monitoring Performance monitors are supported in a limited number of logical switches, depending on the platform type. Refer to Chapter 20, "Monitoring Fabric Performance," for more information about performance monitoring when Virtual Fabrics is enabled. QoS QoS VCs are maintained across the base fabric. Refer to Chapter 21, "Optimizing Fabric Behavior," for more information about using the Adaptive Networking features with Virtual Fabrics. Traffic Isolation Traffic Isolation zones with failover disabled are not supported in logical fabrics. Refer to Chapter 21, "Optimizing Fabric Behavior," for additional information about using TI Zones with Virtual Fabrics. Limitations and restrictions of Virtual Fabrics The maximum number of logical switches per chassis varies depending on the switch model. Table 52 lists the supported platforms and the maximum number of logical switches (including the default logical switch) supported on each.
