Troubleshooting
The switch keeps aging out endstation entries in the switch Forwarding Database (FDB):
Reduce the number of topology changes by disabling STP on those systems that do not use redundant
paths.
Specify that the endstation entries are static or permanent.

Debug Mode

The Event Management System (EMS) provides a standardized way to filter and store messages
generated by the switch. With EMS, you must enable debug mode to display debug information. To
enable or disable debug mode for EMS, use the following commands:
enable log debug-mode
disable log debug-mode
After debug mode has been enabled, you can configure EMS to capture specific debug information from
the switch. Details of EMS can be found in Chapter 8, "Status Monitoring and Statistics," on page 91.

System Health Check

The system health check tests the backplane, the CPU, and I/O modules by periodically forwarding
packets and checking for the validity of these packets. If you observe a failure, please contact Extreme
Technical Support.
To enable system health check, use the following command:
enable sys-health-check slot <slot>
System health check is enabled by default.
To disable the system health checker, use the following command:
disable sys-health-check slot <slot>

System Odometer

Each field replaceable component contains a system odometer counter in EEPROM. You can use the
command to see how long an individual component has been in service since it was

manufactured. The odometer is supported on the following BlackDiamond 10808 components:
• Master MSM and slave MSM
• Backplane
• All modules
