• Create a separate TI zone for each path
• Combine all of the paths in a single TI zone
The option you select affects the failover behavior of the TI zones.
Failover behavior for Fabric-Level TI zones
Fabric-Level Traffic Isolation requires the TI zones in the backbone to have failover enabled. The
failover behavior differs depending on how you create the TI zones.
If you create a separate TI zone for each path:
• If one of the TI zone paths fails, then traffic on that path is re-routed to a non-dedicated path.
For example, in Figure 42 on page 353, if the BLUE path fails, then traffic associated with the BLUE
path is re-routed to a black path.
If you combine all of the paths in a single TI zone:
• If one of the paths in the TI zone fails, then traffic on that path is re-routed to another path in the TI
zone.
For example, in Figure 42 on page 353, if the BLUE path fails, then traffic associated with the BLUE
path is re-routed to the RED path.
Failover behavior for Fabric-Level TI zones is the same as for other TI zones, as described in TI zone
failover on page 342.
Creating a separate TI zone for each path
Create a separate TI zone for each path if you want TI traffic to failover to non-TI zone paths.
This example procedure creates two TI zones in the backbone fabric shown in Figure 42 on page 353.
1. Create TI zones with failover enabled.
Each TI zone must include the ingress and egress EX_Ports, as well as the E_Ports between the
two backbone switches. Do not include the edge fabric E_Ports or device PWWNs.
switch:admin> zone --create -t ti TI_Zone_Red -p "20,5; 20,3; 30,7; 30,9"
switch:admin> zone --create -t ti TI_Zone_Blue -p "20,6; 20,4; 30,8; 30,10"
By default, a new TI zone is configured as "Activated" with failover enabled.
2. Display defined TI zones.
switch:admin> zone --show
Defined TI zone configuration:
TI Zone Name: TI_Zone_Blue
Port List: 20,6; 20,4; 30,8; 30,10
Configured Status: Activated / Failover-Enabled
Enabled Status: Deactivated
TI Zone Name: TI_Zone_Red
Port List: 20,5; 20,3; 30,7; 30,9
Configured Status: Activated / Failover-Enabled
Enabled Status: Deactivated
Note that although the configured status is "Activated", the enabled status is "Deactivated".
3. Activate TI zones.
switch:admin> cfgactvshow
Effective configuration:
