TI zone in a backbone fabric

TI zones within the backbone fabric use the port WWN instead of D,I notation for devices that are to
communicate across fabrics. (You can use the portShow command to obtain the port WWN.) Port
WWNs should be used only in TI zones within a backbone fabric and should not be used in other TI
zones.
Using D,I and port WWN notation, the members of the TI zone in
• 1,1(EX_Port for FC router 1)
• 1,4(VE_Port for FC router 1)
• 2,7(VE_Port for FC router 2)
• 2,1(EX_Port for FC router 2)
• 10:00:00:00:00:01:00:00(Port WWN for the host)
• 10:00:00:00:00:02:00:00(Port WWN for target 1)
• 10:00:00:00:00:03:00:00(Port WWN for target 2)

Limitations of TI zones over FC routers

Be aware of the following when configuring TI zones over FC routers:
• A TI zone defined within the backbone fabric does not guarantee that edge fabric traffic will arrive at a
particular EX_Port. You must set up a TI zone in the edge fabric to guarantee this.
• TI zones within the backbone fabric cannot contain more than one destination router port (DRP) per
each fabric.
• Only one egress VE_Port for each FC router can be defined within TI zones.
• TI over FCR is supported only from edge fabric to edge fabric. Traffic isolation from backbone to edge
is not supported.
• Non-TI data traffic is not restricted from going through the TI path in the backbone fabric.
• For TI over FCR, failover must be enabled in the TI zones in the edge fabrics. The failover mode for TI
zones in the backbone fabric can be enabled or disabled.
• TI over FCR is not supported with FC Fast Write.
