show hardware Commands
Use the show hardware commands to troubleshoot error conditions by displaying information about a hardware
subcomponent and details from hardware-based feature tables.
NOTE: Use the show hardware commands only under the guidance of the Dell Networking Technical Assistance Center
(TAC).
● Display the data plane or management plane input and output statistics of the designated component of the designated
stack member.
stack-unit <id> {buffer [ unit 0 ] total buffer | buffer unit 0 interface all queue
[(0-14) | a11] buffer-info}{cpu data-plane statistics | cpu management statistics | drops
[unit number] | fpga register | party-bus statistics | stack-port | ti-monitor | unit 0-1
{counters | details | port-stats [detail] | register}}
● View internal interface status of the stack-unit CPU port which connects to the external management interface.
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.
show hardware stack-unit {0-11} cpu data-plane statistics
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.
show hardware stack-unit {0-11} buffer total-buffer
● View the modular packet buffers details per unit and the mode of allocation.
show hardware stack-unit {0-11} buffer unit {0-1} total-buffer
● Display buffer statistics for a specific interface.
show hardware buffer interface interface{priority-group { id | all } | queue { id| all} ]
buffer-info
● Display buffer statistics tracking resource information for a specific interface.
show hardware buffer-stats-snapshot resource interface interface{priority-group { id |
all } | queue { ucast{id | all}{ mcast {id | all} | all}
● 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
● Displays internal drops on the specified interface or for a range of interface.
show hardware drops interface interface
● 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
● Display the hardware counters interface.
show hardware counters interface interface
● 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.
show hardware stack-unit {0-11} unit {0-1} table-dump {table name}
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
