Access Gateway mapping

FIGURE 4 Example port-based mapping
Table 4 provides a description of the port mapping in Figure 4 .
Considerations for initiator and target ports
Following are the possible connections to FCP initiator (host) and target ports through AG:
• All F_Ports connect to all initiator ports.
• All F_Ports connected to all target ports.
• Some F_Ports connected to initiator ports and some F_Ports connected to target ports.
For the last case, communication between initiator and target ports is not supported if both are
mapped to the same N_Port. Therefore, follow these recommendations for initiator and target port
mapping:
• If connecting a host and target port to the same AG, you should map them to separate N_Ports
and connect those N_Ports to the same fabric.
• Use separate port groups for initiator and target ports.
