packets on the corresponding switch line card; for example,
line-card CPU 1 processes packets on line card 1.
pe pe-id Enter the pe pe-id parameters to run offline diagnostic
tests only on a specified port extender unit. The PE ID range
is from 0 to 255.
NOTE: The pe option is only available when the feature
extended bridge is enabled.
stack-unit unit-
number
Enter the stack-unit value to run offline diagnostic test
on a specified stack-unit. The stack-unit range is 0 to 7.
alllevels Enter the keyword all levels to run the complete set of
offline diagnostic tests.
level0 Enter the keyword level0 to run Level 0 diagnostics. Level
0 diagnostics check for the presence of various
components and perform essential path verifications. In
addition, they verify the identification registers of the
components on the board.
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. There are no tests
on 10G links. 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.
interactive Enter the keyword interactive to run offline diagnostics
in interactive mode.
NOTE: On a C1048P, interactive diagnostic tests are
supported only in standalone mode; they are not
supported in stacking mode and only from the PE
console.
testname name Enter the testname name parameters to run a specified
offline diagnostic test. Enclose the test-case name in double
quotes (“ “). For example: diag level1 testname
“eepromTest”
.
