Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands
diagnostic start
When specifying a test name, use the show diagnostic content privileged EXEC command to display
the test ID list. To specify test 3 by using the test name, enter the diagnostic start switch number test
TestPortAsicCam privileged EXEC command.
If specifying more than one test to run, use the test-id-range parameter, and enter integers separated by
a comma and a hyphen. For example, to specify tests 2, 3, and 4, enter the diagnostic start switch
number test 2-4 command. To specify tests 1, 3, 4, 5, and 6, enter the diagnostic start switch number
test 1,3-6 command.
After starting the tests by using the diagnostic start command, you cannot stop the testing process.
Examples This example shows how to start diagnostic test 1 on stack member 2 when this command is entered on a
stack master:
Switch# diagnostic start switch 2 test 1
Switch#
06:27:50: %DIAG-6-TEST_RUNNING: Switch 2: Running TestPortAsicStackPortLoopback{ID=1} ...
(switch-1)
06:27:51: %DIAG-6-TEST_OK: Switch 2: TestPortAsicStackPortLoopback{ID=1} has completed
successfully (switch-2)
This example shows how to start diagnostic test 2 on a stack member in a switch stack. Running this test
disrupts the normal system operation, causes the switch to lose stack connectivity, and then causes the
switch to reload.
Switch# diagnostic start switch 1 test 2
Switch 1: Running test(s) 2 will cause the switch under test to reload after completion of
the test list.
Switch 1: Running test(s) 2 may disrupt normal system operation

This message appears if the configured test can cause the switch to lose stack connectivity:
Switch 3: Running test(s) 2 will cause the switch under test to reload after completion of
the test list.
Switch 3: Running test(s) 2 may disrupt normal system operation
