Host 1 Domain 1 8 1 9 2 Front Domain 3 9 10 -1 Host 2 E_Ports EX_Ports -1 = Dedicated Path = Ports in the TI zone Figure 47 TI zone in an edge fabric Xlate Domain 4 Proxy Target In the TI zone, when you designate E_Ports between the front and xlate phantom switches, you must use -1 in place of the "I" in the D,I notation. Both the front and xlate domains must be included in the TI zone. Using D,I notation, the members of the TI zone in Figure 47 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 TI 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 48, 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. 344 Optimizing fabric behavior
