Show hardware system-flow pe pe—id stack-unit unit—number port-set number { counters | }
NOTE: You can also clear the system-flow statistics from the specified port extender hardware component by using the
clear hardware system-flow pe pe—id stack-unit unit—number port-set number { counters
| <cr> } command.
● Display the operational status or the internal ports that are dynamically mapped to a backplane link or control-plane trunk
group that is down.

Troubleshoot a flap or fault condition on a HiGig backplane link by displaying the internal ports that are mapped to backplane
links for control or data traffic and the status of backplane links. In the show hardware bp-link-state command
output, 1 indicates that a backplane link is up; 0 indicates the a link is down. You can also display the traffic utilization of
member interfaces in a HiGig port channel that transmits control or data traffic from the Control Processor or a line card
over the C9000 series backplane. unit defines the Network Processing unit (NPU) of a HiGig port channel. hg-port-
channel defines the HiGig port-channel number.
NOTE:
In the C9000 series CLI, NPUs are sometimes referred to as units.
Besides the front-end I/O ports on line cards, the C9000 series uses six internal SFM units to transmit the data between
line-card ports.
Environmental Monitoring
The system components use environmental monitoring hardware to detect transmit power readings, receive power readings,
and temperature updates.
To receive periodic power updates, enable the enable optic-info-update interval command. The output in the
following example displays the environment status of the RPM.
