clear hardware stack-unit
Clear statistics from selected hardware components.
Syntax
clear hardware stack-unit 0–5 {counters | unit 0–1 counters | cpu data-
plane statistics | cpu party-bus statistics | stack-port 0–52}
Parameters
stack-unit
0–5
Enter the keywords stack-unit then 0 to 5 to select a particular stack member
and then enter one of the following command options to clear a specific collection
of data.
counters Enter the keyword counters to clear the counters on the selected stack member.
unit
0–0
counters
Enter the keyword unit along with a port-pipe number, from 0 to 1 , then the
keyword counters to clear the counters on the selected port-pipe.
cpu data-plane
statistics
Enter the keywords cpu data-plane statistics to clear the data plane
statistics.
cpu party-bus
statistics
Enter the keywords cpu party-bus statistics to clear the management
statistics.
stack-port
33–56
Enter the keywords stack-port then the port number of the stacking port to
clear the statistics of the particular stacking port. The range is from 33 to 56.
NOTE: You can identify stack port numbers by physical inspection of the rear
modules. The numbering is the same as for the 10G ports. You can also inspect
the output of the show system stack-ports command.

Commands
show diag— displays the data plane or management plane input and output statistics of the designated
component of the designated stack member.
diag stack-unit
Run offline diagnostics on a stack unit.
Syntax
diag stack-unit number {alllevels | level0 | level1 | level2 [verbose no-
reboot]| terminate| interactive test <id>}
Parameters
number
Enter the stack-unit number. The range is from 0 to 5.
alllevels Enter the keyword alllevels 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, stack ports are
shut down automatically.
