FIGURE 3 Port usage comparison
You can convert a Fibre Channel port into a D_Port on AG switch and a connected fabric switch or
another AG switch (cascaded configuration) to test the link between the ports. When you configure
the ports on each end of the link as D_Ports, diagnostic tests automatically initiate on the link
when the D_Ports go online. Results can be viewed using Fabric OS commands during or after
testing. Once in D_Port mode, the port does not participate in fabric operations, login to a remote
device, or run data traffic. Figure 4 on page 10 illustrates the supported D_Port configurations.
FIGURE 4 Diagnostic port configurations
Table 4 shows a comparison of port configurations between AG and a standard fabric switch.
