Traffic Isolation Zoning over FC routers
12
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 41 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 42 , 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 42
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.
