Understanding the Error Reading Diagnostics Message

For more detailed infomation about error messages and their meanings, see the ExtremeXOS and Switch Engine 32.2 EMS Messages Catalog .

If you have never run diagnostics on the switch or stack ports and use the show diagnostics command, the switch displays a message similar to the following:

Result: FAIL
Test date run is invalid. Please run Diagnostics.
Error reading diagnostics information.

This message is normal and expected if you have never run diagnostics on the switch. After running diagnostics, you see information about the executed test using the show diagnostics command.
