Traffic Isolation Zoning overview
The Traffic Isolation Zoning feature allows you to control the flow of interswitch traffic by creating a
dedicated path for traffic flowing from a specific set of source ports (N_Ports). 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.
