History
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 [buffer unit | port [(1-56) | all] total buffer | buffer unit (1) port
(1-56)
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 0-1 [port
1-56]] | stack-port 33-56 | unit 0-0 {counters | details | port-stats [detail] | register}}
Parameters
stack-unit 0-5 Enter the keyword stack-unit followed by a numeral from 0 to 5 to
select a stack ID.
port-set 0-0
Enter the keyword port-set with a port-pipe number — 0.
Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module
stack-unit 0-5
{command-option}
Enter the keyword stack-unit followed by 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, optionally followed by the keywords
total-buffer to show the total buffer statistics per stack unit. 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 per port per stack unit, enter the keywords
buffer
unit
followed by port and the port number (1-56 or 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 port (1-56),
and
queue (0-14 or all), and buffer-info.
Buffer unit default: 1
phy-firmware-version
Each member of the stack is updated automatically with the latest firmware
while booting as well as during OIR. Enter the keyword
phy-firmware-version, to dump the physical firmware version for stack
units.
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 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.
