Topology 3: Access Gateways
Figure 61 illustrates a switch configured as a single Access Gateway connected to a fabric switch. N
and F represent, respectively, an N_Port and an F_Port to be configured as D_Ports.
The Access Gateway must be either a Brocade 6505 or 6510.
FIGURE 61 Single Access Gateway to switch
Figure 62 illustrates multiple Access Gateways connected to a switch in a cascaded topology. N
and F represent, respectively, an N_Port and an F_Port to be configured as D_Ports.

For configuration details, refer to “Using D_Port without HBAs” on page 465.
NOTE
N_Port-to-F_Port and device (WWN) mappings must be removed from an Access Gateway port
before configuring the Access Gateway port as a D_Port. Refer to “Saving port mappings on an
Access Gateway” on page 464.
Figure 63 illustrates connectivity between an HBA and an Access Gateway. F represents an F_Port
to be configured as a D_Port.

Saving port mappings on an Access Gateway
Before configuring ports as D_Ports on a switch configured as an Access Gateway, you must
remove N_Port-to-F_Port and device (WWN) mappings. Fabric OS commands are available to save
N_Port mappings. Once you save them, you can display the saved N_Port mappings to reconfigure
them after D_Port is disabled. A command is also available to delete saved N_Port mappings.
For more details, refer to Chapter 2, “Configuring Ports in Access Gateway Mode,” in the Access
Gateway Administrator’s Guide.
