For configuration details see “Using D_Port without HBAs” on page 95.

Topology 3: Access Gateways

Figure 6 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. (See note

below.) The following equipment is supported, in any mix-or-match combination:

• Access Gateways: Brocade 6505, 6510

• Switches: Brocade DCX 8510-4, DCX 8510-8, 6505, 6510, 6520

FIGURE 6 Single Access Gateway to switch

Figure 7 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. (See note below.)

There is no D_Port support for HBA connectivity to the Access Gateway. The following equipment is

supported, in any mix-or-match combination:

• Access Gateways: Brocade 6505, 6510

• Switches: Brocade DCX 8510-4, DCX 8510-8, 6505, 6510, 6520

For configuration details see “Using D_Port without HBAs” on page 95.

NOTE

You cannot configure a D_Port in the above topologies if N_Port-to-F_Port mappings are already

present on the Access Gateway. See“Saving port mappings on an Access Gateway” on page 97.
