Service Manual
• 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.
EXEC Privilege mode
show hardware stack-unit {0-11} unit {0-1} counters
