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.

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) 296 Optimizing fabric behavior
