Traffic isolation zoning
A Traffic Isolation zone (TI zone) is a special zone that isolates inter-switch traffic to a specific,
dedicated path through the fabric. A TI zone contains a list of E_Ports, followed by a list of N_Ports.
When the TI zone is activated, the fabric attempts to isolate all inter-switch traffic between N_Ports
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.
Traffic isolation zoning is only supported with domain and port index number members.
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 disabled failover is not used correctly, it can cause major fabric disruptions that are
difficult to resolve.
Enhanced TI zones
In Fabric OS 6.4.0 or higher, ports can be in multiple TI zones. Zones with overlapping port
members are called
enhanced TI zones
(ETIZ).
Enhanced TI zones are supported only on the following platforms:
•
24-port, 8 Gbps FC Switch
•
40-port, 8 Gbps FC Switch
•
80-port, 8 Gbps FC Switch
•
8 Gbps 12-port Embedded Switch
•
8 Gbps 24-port Embedded Switch
•
8 Gbps 16-port Embedded Switch
•
8 Gbps 24-port Embedded Switch
•
8 Gbps 16-FC ports, 6-Gbit ports Extension Switch
•
24 - 8 Gbps FC Port, 8 - 10 Gbps CEE Port Switch
•
8 Gbps 40-port Switch
•
384-port Backbone Chassis
•
192-port Backbone Chassis
•
8 Gbps Encryption Switch
Enhanced TI zones are supported only if the following conditions are met:
•
Every switch must be one of the supported platforms, as listed above.
•
Every switch must be running Fabric OS v6.4.0 or later.
If the fabric contains a switch running an earlier version of Fabric OS, you cannot create an
enhanced TI zone.
