9.9(0.0) Introduced on the FN IOM.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
show hardware stack-unit
Display the data plane or management plane input and output statistics of the designated component of the designated stack member.
Syntax
show hardware stack-unit 0-5 {buffer [ unit 0 ] total buffer | buffer unit 0
interface all queue [(0-14) | a11] buffer-info}{phy-firmware-version} {cpu
data-plane statistics [stack-port 0-52] | cpu party-bus statistics | cpu
private-mgmt statistics | drops [unit number] | stack-port 33-56 | unit 0-0
{counters | details | port-stats [detail] | register}}
Parameters
stack-unit 0–5
{command-option}
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 display a collection of data based on
the option entered.
buffer Enter the keyword buffer. To display buffer statistics for a all interface, enter the
keyword interface followed by the keyword all. Enter the keywords buffer unit
then total-buffer to display the buffer details per unit and mode of allocation. To
display the forwarding plane statistics containing the packet buffer usage for all interface
per stack unit, enter the keywords buffer unit then interface all and the
inteface all, then buffer-info. To display the forwarding plane statistics
containing the packet buffer statistics per COS per port, enter the keywords buffer
unit, and queue (0-14 or all), and buffer-info. The buffer unit default is 1.
phy-firmware-
version
Each member of the stack is updated automatically with the latest firmware while
booting as well as during OIR. To dump the physical firmware version for stack units,
enter the keywords phy-firmware-version.
cpu data-plane
statistics
(Optional) Enter the keywords cpu data-plane statistics then the keywords
stack port and its number from 0 to 52 to display the data plane statistics, which
shows the High Gig (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.
cpu private-mgmt
statistics
Enter the keywords cpu private-mgmt statistics, to display the Management
plane input/output counter statistics of the Private Management interface.
drops [unit 0] Enter the keyword drops to display internal drops on the selected stack member.
Optionally, use the keyword unit with 0 to select port-pipe 0.
stack-port 33–56 Enter the keywords stack-port 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.
