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.
show hardware linecard slot—id buffer unit unit-number} total-buffer
• Display the forwarding plane statistics containing the packet buffer usage per port per line card.
show hardware linecard slot—id buffer unit unit-number port {port-number | all} buffer-info
• Display the forwarding plane statistics containing the packet buffer statistics per CoS per port.
show hardware linecard slot—id buffer unit unit-number port {port-number} queue {queue—num |
all} buffer-info
• Display input and output statistics on the party bus, which carries inter-process communication traffic between CPUs.
show hardware party-bus {port { slot—id} | all} statistics
• Display the ingress and egress internal packet-drop counters, MAC drop counters, and FP packet drops for the line card on a per port
basis.
show hardware linecard slot—id drops unit unit-number port {port-number}
Use the command output to troubleshoot a line card and port-pipe unit that may experience internal drops.
• Display the input and output statistics for a stack-port interface.
show hardware linecard slot—id unit unit-number
• Display the counters in the field processors of a port-pipe unit on a line card.
show hardware linecard slot—id unit unit-number counters
• Display the details of the FP devices, and HiGig ports on a port-pipe unit on a line card.
show hardware linecard slot—id unit unit-number details
• Execute a specified bShell command from the CLI without going into the bShell.
show hardware linecard slot—id unit unit-number execute-shell-cmd {command}
• Display the Multicast IPMC replication table from the bShell.
