Diagnostic tests and monitoring

Brocade FastIron software includes diagnostic tests to help you troubleshoot the hardware. System diagnostic software is designed to
fulfill the purpose of offline diagnostics. In offline diagnostics, you must turn the diagnostic flags on or off to execute diagnostic tests
during the next bootup.
The CLI commands for system diagnostic tests are dm diag and dm alt-diag. These diagnostic tests verify all available hardware
components including:
•
I2C devices
•
EEPROMS
•
CPU packet
•
Test MAC alignment
•
Line rate
During system diagnostic testing, the system is completely under the control of the diagnostic software. All hardware components are
verified, and results are displayed on the console. In cases where a failure is detected, results and corrective actions will be displayed. After
the system diagnostic testing is complete, the system exits from the diagnostic mode and reloads the system for normal operation.
System diagnostic testing runs at link speeds 10 Gbps and 40 Gbps (QSFP+ ports) depending on the speed of the link being tested and
the type of port.
