Extreme Networks ExtremeWare XOS Command Reference Manual page 1969

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
Extreme Networks. The switch performs a hardware test to confirm that the stack ports are operational;
traffic to and from the ports on the switch is temporarily unavailable. This Bit Error Rate Test (BERT)
provides an analysis of the number of bits transmitted in error.
After the switch runs the diagnostic routine, test results are saved to the switch's EEPROM and
messages are logged to the syslog.
Viewing Diagnostics. To view results of the last diagnostics test run, use the following command:
show diagnostics {slot [<slot> | A | B]}
NOTE
The slot, A, and B parameters are available only on modular switches.
If the results indicate that the diagnostic failed on a module, replace the module with another module of
the same type.
If the results indicate that the diagnostic failed on the switch, contact Extreme Networks Technical
Support.
Example
BlackDiamond 10808 switch and BlackDiamond 8800 series switch example
The following command runs normal diagnostics on the I/O module installed in slot 2 of either the
BlackDiamond 10808 switch or the BlackDiamond 8800 series switch:
run diagnostics normal slot 2
The switch displays a warning similar to the following about the impact of this test. You also have the
opportunity to continue or cancel the test:
Running Diagnostics will disrupt network traffic.
Are you sure you want to continue? (y/n)
Enter to continue and run the diagnostics. Enter
y
BlackDiamond 12804 switch example
The following command runs normal diagnostics on all of the installed I/O modules and the primary
MSM of the BlackDiamond 12804 switch:
run diagnostics normal
The switch displays a warning similar to the following about the impact of this test. You also have the
opportunity to continue or cancel the test:
Running Diagnostics will disrupt network traffic.
Are you sure you want to continue? (y/n)
Enter to continue and run the diagnostics. Enter
