• The TI zones appear in the defined zone configuration only and do not appear in the effective zone configuration. A TI zone only provides Traffic Isolation and is not a "regular" zone. • A TI zone must include a set (two or more) of E_Ports forming an end-to-end path. Inclusion of N_Ports is optional. • Each TI zone is interpreted by each switch and each switch considers only the routing required for its local ports. No consideration is given to the overall topology and to whether the TI zones accurately provide dedicated paths through the whole fabric. For example, in Figure 28, the TI zone was configured incorrectly and E_Port "3,9" was erroneously omitted from the zone. The domain 3 switch assumes that traffic coming from E_Port 9 is not part of the TI zone and so that traffic is routed to E_Port 11 instead of E_Port 12, if failover is enabled. If failover is disabled, the route is broken and traffic stops. • You create and modify TI zones using the zone command. Other zoning commands, such as zoneCreate, aliCreate, and cfgCreate, cannot be used to manage TI zones.

This feature is not supported in fabrics configured in any interopMode except for a predefined FICON FCIP configuration in McDATA Fabric Mode. • VE_Ports are supported in TI zones. 286 Optimizing fabric behavior
