Traffic Isolation Zoning over FC routers
12
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 40, 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 40 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.
Using D,I and port WWN notation, the members of the TI zone in Figure 40 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)
