level1 Enter the keyword
Level1
to run Level 1 diagnostics. Level 1
diagnostics is a smaller set of diagnostic tests with support for
automatic partitioning. They perform status/self test for all the
components on the board and test their registers for appropriate
values. In addition, they perform extensive tests on memory
devices (for example, SDRAM, flash, NVRAM, EEPROM, and
CPLD) wherever possible. At this level, ports are shut down
automatically.
level2 Enter the keyword
level2
to run Level 2 diagnostics. Level 2
diagnostics are a full set of diagnostic tests with no support for
automatic partitioning. Level 2 diagnostics are used primarily for
on-board loopback tests and more extensive component
diagnostics. Various components on the board are put into
Loopback mode and test packets are transmitted through those
components. These diagnostics also perform snake tests using
VLAN configurations.

Usage Information Before you use this command to run diagnostic test, make sure that the port extender
(PE) stack-unit is offline (
offline stack-unit unit number
command). You are
prompted to reboot when the offline diagnostics is complete.
The PE unit goes offline and reboots automatically after the test is completed. Once the
test is finished, the diag report is generated, and it is stored in the PE flash. To view the
diag report, use the
show diag pe pe-id stack-unit unit-number
command
from C9000 system. The
show diag pe
command uploads the TestReport from the
PE to the C9000.
The filename of the TestReport is:
TestReport-SU-Stack-Unit-Number-PE-pe-
id-Year_Month_Day_Unique-Tag.txt
, where SU identifies the PE stack-unit on
which the offline diag test was run,
Year_Month_Day
is a timestamp to identify when
the offline diag test was run for that unit, and the
Unique Tag
is to identify that
specific diag test. Diag test reports on PE are not overwritten. Offline diag test reports
