FIGURE 39 Traffic Isolation Zoning over FCR
In addition to setting up TI zones, you must also ensure that the devices are in an LSAN zone so that
they can communicate with each other.
If failover is enabled and the TI path is not available, an alternate path is used. If failover is disabled and
the TI path is not available, then devices are not imported.
TI zones within an edge fabric
A TI zone within an edge fabric is used to route traffic between a real device and a proxy device through
a particular EX_Port.
For example, in Figure 40 , you can set up a TI zone to ensure that traffic between Host 1 and the proxy
target is routed through EX_Port 9.
