Enter the keywords cp with a command option to display
hardware statistics from the Control Processor. The
command options are:
• cpu data-plane statistics: Displays data-plane
statistics, including the HiGig port statistics with input/
output counters to which the stacking module is
connected.
• cpu i2c statistics : Displays active i2c-address
statistics.
• cpu management statistics: Displays management
port counters.
• cpu sata-interface statistics: Displays sata-
interface error counter statistics.
Enter the keyword cp-switch with a command option to

for for all interface in a specified port-pipe.. The range of
port-pipe unit numbers is 0 to 3.
•
buffer unit unit-num total-buffer
statistics: Displays the number of buffers allocated
for a specified NPU. The range of NPU numbers is 0 to 3.
• cpu data-plane statistics: Displays data-plane
statistics, including the HiGig port statistics with input/
