FIGURE 40 TI zone in an edge fabric

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 40

are as follows:

• 1,8
• 1,1
• 3,-1 (E_Port for the front phantom domain)
• 4,-1 (E_Port for the xlate phantom domain)

NOTE
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 zones 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 41

, 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".
