BlackDiamond X8 and 8800 Series Switches

If you run the diagnostic routine on an I/O or Fabric module (BlackDiamond X8 series only), that module is taken offline while the diagnostic test is performed. Traffic to and from the ports on that I/O or Fabric (BlackDiamond X8 series only) module is temporarily unavailable. When the diagnostic test is complete, the module is reset and becomes operational again.

If you run diagnostics on an MSM/MM, that module is taken offline while the diagnostics test is performed. When the diagnostic test is complete, the MSM/MM reboots and becomes operational again.

If you run diagnostics on the primary MSM/MM, the backup MSM/MM assumes the role of the primary and takes over switch operation.

After the MSM/MM completes the diagnostic routine and reboots, you can initiate failover from the new primary MSM/MM to the original primary MSM/MM. Before initiating failover, confirm that both MSMs/MMs are synchronized using the show switch command. If the MSMs/MMs are synchronized, initiate failover using the run msm-failover command. For more detailed information about system redundancy and MSM/MM failover, see GUID-18238ACD-D9D5-4B4A-8449-E79687EAEFFD.

Run diagnostics on one MSM/MM at a time. After you run the diagnostic routine on the first MSM/MM, use the show switch command to confirm that both MSMs/MMs are up, running, and synchronized before running diagnostics on the second MSM/MM.

After the switch runs the diagnostic routine, test results are saved in the module‘s EEPROM and messages are logged to the syslog.

Run diagnostics on I/O, Fabric (BlackDiamond X8 series only), or MSM/MM modules with the following command:

run diagnostics [extended | normal | stack-port] {slot [slot | A | B]}

Where the following is true:

extended—Takes the switch fabric and ports offline and performs extensive ASIC, ASIC-memory, and packet loopback tests. Extended diagnostic tests take approximately 15 to 20 minutes to complete. The CPU is not tested. Console access is available during extended diagnostics.

If you have a Power over Ethernet (PoE) module installed, the switch also performs an extended PoE test, which tests the functionality of the inline power adapter.

normal—Takes the switch fabric and ports offline and performs a simple ASIC and packet loopback test on all ports.
slot—Specifies the slot number of an I/O or Fabric (BlackDiamond X8 series only) module. When the diagnostic test is complete, the system attempts to bring the module back online.
Note

BlackDiamond 8800 series switches—To run diagnostics on the management portion of the master MSM, specify slot A or B. If an I/O subsystem is present on the MSM, then that I/O subsystem will be non-operational until diagnostics are completed.

BlackDiamond 8810 switch—If you run diagnostics on slots 5 and 6 with an MSM installed in those slots, the diagnostic routine tests the I/O subsystem of the MSM.

BlackDiamond 8806 switch—If you run diagnostics on slots 3 and 4 with an MSM installed in those slots, the diagnostic routine tests the I/O subsystem of the MSM.
A | B—Specifies the slot letter of the primary MSM. The diagnostic routine is performed when the system reboots. Both switch fabric and management ports are taken offline during diagnostics.
Note
BlackDiamond X8 and 8800 series switches do not allow you to run diagnostics on a module that has been disabled. Command line interface message: Cannot run diags because I/O card is not Operational or Offline Current state is Down.
