Diagnostics
NOTE
Only run these diagnostics when the switch can be brought off-line. The tests performed are extensive
and affect traffic that must be processed by the system CPU, because the diagnostics themselves are
processed by the system CPU.

Running the Diagnostics on Summit “ e” Switches
To run the diagnostics on a Summit “ e ” system, use this command:
run diagnostics [extended | normal | stack-port]
where:
System Impact of Running the Diagnostics on Summit “ e” Series Switches
These diagnostics are invasive diagnostics. The diagnostics perform different tests, depending on
whether the test is being performed on the CPU subsystem or an individual I/O module. The
diagnostics reset and erase all current hardware states. On the Summit “e” series switches, when the
runtime diagnostics are activated (or the switch fails), the switch is offline and reboots.
When you enter the
run diagnostics
command on a Summit “ e ” series switch, the test routine will
display a message prompting you to confirm the diagnostic action. For example,
Running Normal diagnostics will reset the switch and disrupt network traffic.

Automatic Packet Memory Scan (via sys-health-check)
An automatic packet memory scan is set up when the system health check
auto-recovery
option is
enabled (see “System (CPU and Backplane) Health Check” on page 70 ). When system health checks fail
at the specified frequency, packet memory scanning is invoked automatically.
NOTE
The automatic packet memory scan and system health check features are supported only on “i” series
Summit, Alpine, and BlackDiamond switches.
extended
(All Summit “ e” switches.) The extended test routine takes 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.
normal
(All Summit “ e” switches.) The normal test routine takes 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.
stack-port
(Summit 400 switches only.) The stack-port option runs the diagnostic test routine on
the stacking port of the Summit 400 switch.
