Display the data plane or management plane input and output statistics of the designated component of 
the designated stack member. 
Syntax

party-bus statistics | drops [unit 0-1 [port 0-27]] | stack-port 0-52 | unit 0-1 {counters | 
details | port-stats [detail] | register}}

stack-unit 0-7 
{command-option}
Enter the keyword stack-unit followed by 0 to 7 to select a particular 
stack member and then enter one of the following command options 
to display a collection of data based on the option entered.
cpu data-plane 
statistics
Enter the keywords cpu data-plane statistics, optionally followed by 
the keywords 
stack port and its number — 0 to 52 — to display the data 
plane statistics, which shows the Higig port raw input/output counter 
statistics to which the stacking module is connected.
cpu party-bus statistics Enter the keywords cpu party-bus statistics, to display the 
Management plane input/output counter statistics of the pseudo party bus 
interface.
drops [unit 0-1 [port 
0-27]]
Enter the drops keyword to display internal drops on the selected 
stack member. Optionally, use the unit keyword with 0 or 1 to select 
port-pipe 0 or 1, and then use port 0-27 to select a port on that 
port-pipe. 
stack-port 0-52 Enter this keyword and a stacking port number to select a stacking 
port for which to display statistics. Identify the stack port number as 
you would to identify a 10G port that was in the same place in one of 
the rear modules.
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.
unit 0-1 {counters | 
details | port-stats 
[detail] | register}
Enter the unit keyword followed by 0 or 1 for port-pipe 0 or 1, and 
then enter one of the following keywords to troubleshoot errors on 
the selected port-pipe and to give status on why a port is not coming 
up to register level: counters, details, port-stats [detail], or 
register
Version 7.8.1.0
Modified: 
stack-port keyword range expanded from 49-52 to 0-52; output modified 
for the 
cpu data-plane statistics option; the following options were added: 
drops [unit 0-1 [port 0-27]] ; unit 0-1 {counters | details | port-stats 
[
detail] | register}
