Diagnostic Port (D_Port)

1. Disable Port 1 on Switch A, by using the portDisable [slot/]port command.
switchA:admin> portdisable 1
2. Configure Port 1 on Switch A as a D_Port, by using portCfgDport - -enable [slot/]port.
switchA:admin> portcfgdport --enable 1
3. Repeat steps 1 and 2 for the corresponding port (in this example Port 2) on Switch B.
switchB:admin> portdisable 2
switchB:admin> portcfgdport --enable 2
4. Enable Port 1 on Switch A by using the portEnable [slot/]port command.
switchA:admin> portenable 1
5. Enable Port 2 on Switch B using the portEnable [slot/]port command.
switchB:admin> portenable 2
NOTE
The basic test suite starts as soon as both ports are enabled. The order in which they are enabled
does not matter.
6. While the test is running, enter the portDportTest [slot/]port - -show command to view test
results. The following test is successful.
switch:admin> portdporttest --show 10/39
