Enter the cp unit-id parameters to run offline diagnostic tests
only on the Control Processor CPU. The Control Processor CPU
ID is 0.
Enter the linecard unit-id parameters to run offline
diagnostic tests only on a specified line card. The linecard slot-id
range is from 0 to 11. Each line-card CPU processes packets on
the corresponding switch line card; for example, line-card CPU
1 processes packets on line card 1.
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.
Enter the stack-unit value to run offline diagnostic test on a
specified stack-unit. The stack-unit range is 0 to 7.
Enter the keyword all levels to run the complete set of
offline diagnostic tests.
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.
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.
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.
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.
