Traffic Isolation Zoning overview
12
Figure 34
shows a fabric with a TI zone consisting of the following:
•
N_Ports:
“1,7”, “1,8”, “4,5”, and “4,6”
•
E_Ports:
“1,1”, “3,9”, “3,12”, and “4,7”
The dotted line indicates the dedicated path between the initiator in Domain 1 to the target in
Domain 4.

In
Figure 34
, all traffic entering Domain 1 from N_Ports 7 and 8 is routed through E_Port 1.
Similarly, traffic entering Domain 3 from E_Port 9 is routed to E_Port 12, and traffic entering
Domain 4 from E_Port 7 is routed to the devices through N_Ports 5 and 6. Traffic coming from
other ports in Domain 1 would
not
use E_Port 1, but would use E_Port 2 instead.
Use the zone command to create and manage TI zones. Refer to the
Fabric OS Command
Reference
for details about the zone command.
TI zone failover
A TI zone can have failover enabled or disabled.
Disable failover if you want to guarantee that TI zone traffic uses only the dedicated path, and that
no other traffic can use the dedicated path.
Enable failover if you want traffic to have alternate routes if either the dedicated or non-dedicated
paths cannot be used.
ATTENTION
If failover is disabled, use care when planning your TI zones so that non-TI zone devices are not
isolated. If this feature is not used correctly, it can cause major fabric disruptions that are difficult
to resolve. See
“Additional considerations when disabling failover”
on page 269 for additional
information about using this feature.
Table 52
compares the behavior of traffic when failover is enabled and disabled.
