296 Optimizing fabric behavior
Using D,I notation, the members of the TI zone in Figure 31 are:
• 1,8
• 1,1
• 3,-1 (E_Port for the front phantom domain)
• 4,-1 (E_Port for the xlate phantom domain)
Note that in this configuration the traffic between the front and xlate domains can go through any path
between these two domains. The -1 does not identify any specific ISL. To guarantee a specific ISL, you need
to set up a zone within the backbone fabric.
TI within a backbone fabric
A TI zone within a backbone fabric is used to route traffic within the backbone fabric through a particular
ISL. For example, in Figure 32, a TI zone is set up in the backbone fabric to ensure that traffic between
EX_Ports 1,1 and 2,1 is routed through VE_Ports 1,4 and 2,7.
Figure 32 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 (use the portShow command to obtain the port WWN). Port WWNs should
be used only in TI zones with 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 Figure 32 are:
• 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)
