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 specied 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 trac is internal (IPC trac) or network
control trac, which the CPU must process.
• View the modular packet buers 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 buers 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 buer 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 buer 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 trac 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}
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 {0-5} stack-port {33–56}
• View the counters in the eld processors of the stack unit.
