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 { 1–6 } 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 { 1–6 } 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 { 1–6 } buffer total-buffer
• View the modular packet buffers details per unit and the mode of allocation.
EXEC Privilege mode
show hardware stack-unit { 1–6 } 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 { 1–6 } 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 { 1–6 } 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 { 1–6 } 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 { 1–6 } drops unit { 0-1 } port { 1-64 }
