Extended System Diagnostics
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.

indicate soft, transient errors or hard faults.
The extended system diagnostics test the following switch elements (depending on the switch
type—Summit or Alpine vs. BlackDiamond, and—for BlackDiamond systems—whether the module
type being tested is an MSM or an I/O module):
type—Summit or Alpine vs. BlackDiamond, and—for BlackDiamond systems—whether the module
type being tested is an MSM or an 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
•
Packet memory test (where possible, this test also attempts to remap up to eight errors)
•
Additional loop-back tests: Big packet (4k) MAC, transceiver, VLAN
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.
