show hardware stack-unit {1–12} 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 {1–12} 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 input and output statistics on the party bus, which carries inter-process communication traffic between CPUs.
EXEC Privilege mode
show hardware stack-unit {1–12} 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 {1–12} drops unit {0-0}
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 {1–12} stack-port {portnumber}
• View the counters in the field processors of the stack unit.
EXEC Privilege mode
show hardware stack-unit {1–12} unit {0-0} counters
• View the details of the FP Devices and Hi gig ports on the stack-unit.
EXEC Privilege mode
show hardware stack-unit {1–12} unit {0-0} details
• View the Multicast IPMC replication table from the bShell.
EXEC Privilege mode
show hardware stack-unit {1–12} unit {0-0} ipmc-replication
• View the internal statistics for each port-pipe (unit) on per port basis.
EXEC Privilege mode
show hardware stack-unit {1–12} unit {0-0} port-stats [detail]
• View the stack-unit internal registers for each port-pipe.
EXEC Privilege mode
show hardware stack-unit {1–12} unit {0-0} register
• View the tables from the bShell through the CLI without going into the bShell.
EXEC Privilege mode
show hardware stack-unit {1–12} unit {0-0} table-dump {table name}
Enabling Environmental Monitoring
The device components use environmental monitoring hardware to detect transmit power readings, receive power readings, and
temperature updates.
To receive periodic power updates, you must enable the following command.
• Enable environmental monitoring.
