Dell Force10 Z9000 Configuration Manual page 826

It 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.

• View the modular packet buffers details per unit and the mode of allocation.

• View the forwarding plane statistics containing the packet buffer usage per port per stack unit.
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.
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.
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.
show hardware stack-unit {0-11} drops unit {0-1} port {1-64}
This helps identify the stack unit/port pipe/port that may experience internal drops.
• View the input and output statistics for a stack-port interface.
show hardware stack-unit {0-11} stack-port {0-64}
• View the counters in the field processors of the stack unit.
show hardware stack-unit {0-11} unit {0-1} counters
• View the details of the FP Devices, and Hi gig ports on the stack-unit.
show hardware stack-unit {0-11} unit {0-1} details
• Execute a specified bShell command from the CLI without going into the bShell.
show hardware stack-unit {0-11} unit {0-1} execute-shell-cmd {command}
• View the Multicast IPMC replication table from the bShell.
show hardware stack-unit {0-11} unit {0-1} ipmc-replication
• View the internal statistics for each port-pipe (unit) on per port basis.
show hardware stack-unit {0-11} unit {0-1} port-stats [detail]
• View the stack-unit internal registers for each port-pipe.
show hardware stack-unit {0-11} unit {0-1} register
• View the tables from the bShell through the CLI without going into the bShell.

The Z9000 supports thirty–two 40G ports or one-hundred twenty–eight 10G ports on four port-pipes, which are also called units.
The system displays internal port numbers, not the external port numbers that you see. For information that maps the internal unit
port number with the port-pipe unit for the 40G (highlighted lines only) and 10G ports (all lines), refer to the following table.
