● pe pe–id — Enter the keyword pe and port extender ID. Range is 0– 255.
● stack-unit number — Enter the keyword stack-unit and a stack unit number. Stack unit range is 0 –7.
● Upload a trace-log file from a switch CPU.

Last Restart Reason
If a switch restarted for some reason (automatically or manually), the show rpm slot-id and show linecard slot-id
command outputs include the reason for the restart.
The following table shows the reasons displayed in the output and their corresponding causes.

show hardware Commands
Use the show hardware commands to troubleshoot error conditions by displaying information about a hardware
subcomponent and details from hardware-based feature tables.
NOTE:
Use the show hardware commands only under the guidance of the Dell Networking Technical Assistance Center
(TAC).
● Display internal interface status of the line-card CPU port which connects to the external management interface.
show hardware linecard slot—id cpu management statistics
● Display driver-level statistics for the data-plane port on the CPU for the specified line card.
show hardware linecard slot—id cpu data-plane statistics
The command output provides details about the packet types entering the CPU to see whether CPU-bound traffic is internal
(IPC traffic) or network control traffic, which the CPU must process.
● Display internal status and driver-level CPU port statistics of the Control Processor and Route Processor.
show hardware cp cpu {data-plane | i2c| management | sata-interface} statistics
show hardware rp cpu {data-plane | i2c| management | sata-interface} statistics
The command output provides details about the packet types entering the CPU to see whether CPU-bound traffic is internal
(IPC traffic) or network control traffic, which the CPU must process.
● Display detailed information on the modular packet buffers per line card and the mode of allocation.
show hardware linecard slot—id buffer total-buffer
● Display hardware ACL Information
show hardware { ip | ipv6 | mac } { in-acl | eg-acl } stack-unit 0 port-set
● Display Hardware Buffer Configurations, Counters.
show hardware {linecard <0-11> | pe <1-255> stack-unit <0-7>} buffer unit <0-0> port buffer-info
● Display the modular packet buffers details per unit and the mode of allocation.
