Using the Show Hardware Commands
The
show hardware
command tree consists of commands used with the system. These commands display information from a
hardware sub-component and from hardware-based feature tables.
NOTE: Use the
show hardware
commands only under the guidance of the Dell Technical Assistance Center.
The following lists the show hardware commands available as of the latest Dell Networking OS version.
• View internal interface status of the stack-unit CPU port which connects to the external management interface.
EXEC Privilege mode
show hardware stack-unit { 0-11 } cpu management statistics
• View driver-level statistics for the data-plane port on the CPU for the specified stack-unit.
EXEC Privilege mode
show hardware stack-unit { 0-11 } cpu data-plane statistics
This view provides insight into 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.
• View the modular packet buffers details per stack unit and the mode of allocation.
EXEC Privilege mode
show hardware stack-unit { 0-11 } buffer total-buffer
• View the modular packet buffers details per unit and the mode of allocation.
EXEC Privilege mode
show hardware stack-unit { 0-11 } buffer unit { 0-1 } total-buffer
• View the forwarding plane statistics containing the packet buffer usage per port per stack unit.
EXEC Privilege mode
show hardware stack-unit { 0-11 } buffer unit { 0-1 } port { 1-64 | all} buffer-info
• View the forwarding plane statistics containing the packet buffer statistics per COS per port.
EXEC Privilege mode
show hardware stack-unit { 0-11 } buffer unit { 0-1 } port { 1-64 } queue { 0-14 | all} buffer-
info
• View input and output statistics on the party bus, which carries inter-process communication traffic between CPUs.
EXEC Privilege mode
show hardware stack-unit { 0-11 } cpu party-bus statistics
• View the ingress and egress internal packet-drop counters, MAC counters drop, and FP packet drops for the stack unit on per
port basis.
EXEC Privilege mode
show hardware stack-unit { 0-11 } drops unit { 0-1 } port { 1-64 }
This view helps identifying the stack unit/port pipe/port that may experience internal drops.
• View the input and output statistics for a stack-port interface.
EXEC Privilege mode
show hardware stack-unit { 0-11 } stack-port { 0-64 }
• View the counters in the field processors of the stack unit.
