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. Depending on the switch platform and model—differences in hardware architecture
determine what aspects of the diagnostic tests apply, these tests are activated by different commands
and different user-configurable options.
• "i" series switches—The BlackDiamond family of core chassis switches (6804, 6808, and 6816), the
Alpine systems (3802, 3804, 3808), and the Summit "i"-series stackables (Summit1i, Summit5i,
Summit7i, Summit 48i, and Summit48Si).
• "e" series switches—Summit 200-24, Summit 200-48, Summit 300-24, Summit 300-48,
Summit 400-24p, Summit 400-24t, and Summit 400-48t.
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.
Runtime Diagnostics on " i " Series Systems
On "i" series systems, there are three categories of 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.
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)
• Extended System Diagnostics—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.
These diagnostics test hardware components to verify basic system integrity. These diagnostics are
invasive. You should use these diagnostics when the syslog displays some intermittent or sporadic
error messages that might indicate a problem, but does not provide sufficient information to confirm
the problem or isolate the fault. The extended system diagnostics help verify whether the error
messages indicate soft, transient errors or hard faults.
The extended system diagnostics test the same set of switch elements as the normal diagnostics
described above (depending on the switch type—Summit or Alpine vs. BlackDiamond, and—for
