For example, you might use Traffic Isolation Zoning for the following scenarios: • To dedicate an ISL to high priority, host-to-target traffic. • To force high volume, low priority traffic onto a given ISL to limit the effect on the fabric of this high traffic pattern. • To ensure that requests and responses of FCIP-based applications such as tape pipelining use the same VE_Port tunnel across a metaSAN. Traffic Isolation Zoning does not require a license. Traffic isolation is implemented using a special zone, called a Traffic Isolation zone (TI zone). A TI zone indicates the set of N_Ports and E_Ports to be used for a specific traffic flow. When a TI zone is activated, the fabric attempts to isolate all inter-switch traffic entering from a member of the zone to only those E_Ports that have been included in the zone. The fabric also attempts to exclude traffic not in the TI zone from using E_Ports within that TI zone. Fabric OS Administrator's Guide 267 53-1001763-01
