Virtual Fabrics considerations for Traffic Isolation Zoning 12 Virtual Fabrics considerations for Traffic Isolation Zoning This section describes how TI zones work with Virtual Fabrics. See Chapter 10, "Managing Virtual Fabrics," for information about the Virtual Fabrics feature, including logical switches and logical fabrics. TI zones can be created in a logical fabric like in regular fabrics, with the following exceptions: • The disable failover option is not supported in logical fabrics that use XISLs. Although logical switches that use XISLs allow the creation of a TI zone with failover disabled, this is not a supported configuration. Base switches do not allow the creation of a TI zone with failover disabled. • To create a TI zone for a logical fabric that uses XISLs, you must create two TI zones: one in the logical fabric and one in the base fabric. The combination of TI zones in the base fabric and logical fabric sets the path through the base fabric for logical switches. The TI zone in the logical fabric includes the extended XISL (XISL) port numbers, as well as the F_Ports and ISLs in the logical fabric. The TI zone in the base fabric reserves XISLs for a particular logical fabric. The base fabric TI zone should also include ISLs that belong to logical switches participating in the logical fabric. Figure 42 shows an initiator and target in a logical fabric (FID1). The dotted line indicates a dedicated path between initiator and target. The dedicated path passes through the base fabric over an XISL. (Figure 42 shows only physical ISLs, not logical ISLs.) To create the TI zones for this dedicated path, you must create a TI zone in the logical fabric (FID 1) and one in the base fabric.

To create the dedicated path, you must create and activate a TI zone in FID1 that includes the circled ports shown in Figure 43. Fabric OS Administrator's Guide 361 53-1002745-02
