Using the Show Hardware Commands
The show hardware command tree consists of commands used with the Aggregator switch.
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.
• View internal interface status of the stack-unit CPU port which connects to the external management
interface.
EXEC Privilege mode
show hardware stack-unit {0-5} 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 {0-5} 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 {0-5} buffer total-buffer
• View the modular packet buffers details per unit and the mode of allocation.
EXEC Privilege mode
show hardware stack-unit {0-5} 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 {0-5} 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 {0-5} 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 {0-5} 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 {0-5} drops unit {0-0} port {33–56}
