Runtime (On-Demand) System Diagnostics

The ExtremeWare diagnostics test suite offers a set of one-time test routines that can be run on demand
by user command on specific slots in a BlackDiamond switch. These tests check the CPU subsystem, the
switch fabric subsystem (MSMs and I/O modules), and control and data path communication. These
tests offer user-configurable options and can also be run on Alpine and Summit systems, where
differences in hardware architecture determine what aspects of the diagnostics tests apply.
There are three categories runtime diagnostics:
• Normal System Diagnostics—These tests take the switch fabric and ports offline and perform a
simple, fast ASIC and packet loopback test on all switch fabric ports. The normal tests are completed
in approximately 30 seconds.
• Extended System Diagnostics on page 58—These tests take the switch fabric and ports offline and
perform extensive ASIC, ASIC-memory, and packet loopback tests. The extended tests take a
maximum of 15 minutes.
• On Demand Packet Memory Scan on page 59—The packet memory test scans the switch fabric in the
switch (Summit or Alpine) or the module in the specified slot (BlackDiamond only) for single-bit
packet memory defects.

Normal System Diagnostics

The normal system diagnostics test the following switch elements (depending on the switch
type—Summit or Alpine vs. BlackDiamond, and—for BlackDiamond systems—the module type being
tested: MSM or I/O module):
• Register ASIC on the CPU
• Real Time Clock
• Management port PCI memory, PCI interface, and transceiver loopback
• Register ASICs (Twister, Quake, MAC, Triumph ASICs)
• Memory (Twister ACL, Quake external memory, MAC memory, Triumph external memory)
• Built-in self test (BIST) in ASICs (Twister, MAC, Triumph)
• Loop-back test (ready state initialization; MAC loop-back test; IP route loop-back test)
NOTE
Only run these diagnostics when the switch or module can be brought off-line. The tests performed are
extensive and affect traffic that must be processed by the system CPU, because the diagnostics are
processed by the system CPU.
