Diagnostic Port (D_Port)

Supported topologies
The following supported topologies illustrate at a high level how D_Port functionality can be used:
• “Topology 1: ISLs” on page 93
• “Topology 2: ICLs” on page 93
• “Topology 3: Access Gateways” on page 94
• “Topology 4: HBA to switch” on page 95
NOTE
In all of these topologies, both automatic and manual D_Port configuration and test modes are
supported. HBAs also support dynamic D_Port mode. For test output examples, see “Example test
scenarios and output” on page 100.
Topology 1: ISLs
Figure 4 illustrates ISLs that connect multiple switches through a pair of chassis. E represents
E_Ports to be configured as D_Ports. The following equipment is supported, in any mix-or-match
combination:
• Switches: Brocade DCX 8510-4, DCX 8510-8, 6505, 6510, 6520

For configuration details see “Using D_Port without HBAs” on page 95.
Topology 2: ICLs
Figure 5 illustrates ICLs between slots 5 and 8 in corresponding chassis. E represents E_Ports to
be configured as D_Ports. The following equipment is supported, in any mix-or-match combination:
• Chassis: Brocade DCX 8510-8, DCX 8510-4
