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.
