Command Modes
EXEC Privilege
stack-unit id Enter the keyword stack-unit to select a particular stack member and
then enter one of the following command options to clear a specific
collection of data.
Unit ID range:
S4810 range: 0-11
Z9000: 0
counters Enter the keyword counters to clear the counters on the selected stack
member.
unit 0–5 counters Enter the keyword unit along with a port-pipe number, from 0 to 5,
followed by the keyword counters to clear the counters on the selected
port-pipe.
Note: S25 models (S25N, S25P, S25V, etc.) have only port-pipe 0.
cpu data-plane statistics Enter the keywords cpu data-plane statistics to clear the data plane
statistics.
cpu i2c statistics Z9000 only: Enter the keywords cpu i2c statistics to clear the i2c
statistics.
cpu party-bus statistics Enter the keywords cpu party-bus statistics to clear the management
statistics.
cpu sata-interface
statistics
Z9000 only: Enter the keywords cpu sata-interface statistics to clear
the sata interface error counting statistics.
stack-port 0–52 S-Series only: Enter the keyword stack-port followed by the port number
of the stacking port to clear the statistics of the particular stacking port.
Range: 0 to 52
