Concept Guide

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 specied 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 trac is internal (IPC
trac) or network control trac, 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 trac is internal (IPC
trac) or network control trac, which the CPU must process.
• Display detailed information on the modular packet buers 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 Buer Congurations, Counters.
show hardware {linecard <0-11> | pe <1-255> stack-unit <0-7>} buer unit <0-0> port buer-info
• Display the modular packet buers 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 buer 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 buer 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 trac 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 eld 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 specied 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.
show hardware unit unit-number ipmc-replication
