2. Configure Port 1 on Switch A as a D_Port in static mode.
switchA:admin> portcfgdport --enable 1
3. Repeat Step 1 and Step 2 for the corresponding port (in this example, Port 2) on Switch B.
switchB:admin> portdisable 2
switchB:admin> portcfgdport --enable 2
4. Reenable Port 1 on Switch A.
switchA:admin> portenable 1
5. Renable Port 2 on Switch B.
switchB:admin> portenable 2
The basic test suite starts as soon as both ports are enabled and ready to perform the test.
6. While the test is running, you can enter a variety of show commands to confirm the D_Port configuration and view test results
on an interface. See "Using D_Port show commands" at the end of this chapter.
To view D_Port status and test results for an interface:
switch:admin> portdporttest --show 10/0/39

Optional : To stop the test on both ends, use the portDportTest --stop command on both the ends. After stopping the test,
verify manually that the test has stopped on both ends. You can restart the test on both ends using the portDportTest --start/
restart command on any one of the ends. You do not need to run the same command on both ends of a single connection
