Environmental Monitoring
The MXL Switch 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
enable optic-info-update interval command. The output in Figure 39-4 shows the environment status.
Table 39-1. show hardware Commands
Command Description
show hardware stack-unit {0-5} cpu management
statistics
View the internal interface status of the stack-unit CPU port which
connects to the external management interface.
show hardware stack-unit {0-5} cpu data-plane
statistics
View the driver-level statistics for the data-plane port on the CPU for the
specified stack-unit. 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.
show hardware stack-unit {0-5} buffer total-buffer
View the modular packet buffers details per stack unit and the mode of
allocation.
show hardware stack-unit {0-5} buffer unit {0-1}
total-buffer
View the modular packet buffers details per unit and the mode of
allocation.
show hardware stack-unit {0-5} buffer unit {0-1}
port {1-64 | all} buffer-info
View the forwarding plane statistics containing the packet buffer usage per
port per stack unit.
show hardware stack-unit {0-5} buffer unit {0-1}
port {1-64} queue {0-14 | all} buffer-info
View the forwarding plane statistics containing the packet buffer statistics
per COS per port.
show hardware stack-unit {0-5} cpu party-bus
statistics
View input and output statistics on the party bus, which carries
inter-process communication traffic between CPUs.
show hardware stack-unit {0-5} drops unit {0-0}
port {33-56}
View the ingress and egress internal packet-drop counters, MAC counters
drop, and FP packet drops for the stack unit on per port basis. It assists in
identifying the stack unit/port pipe/port that may experience internal drops.
show hardware stack-unit {0-5} stack-port
{33-56}
View the input and output statistics for a stack-port interface.
show hardware stack-unit {0-5 unit {0-0} counters
View the counters in the field processors of the stack unit.
show hardware stack-unit {0-5} unit {0-0} details
View the details of the FP devices and Hi gig ports on the stack-unit.
show hardware stack-unit {0-5} unit {0-0}
execute-shell-cmd {command}
Execute a specified bShell commands from the CLI without going into the
bShell.
show hardware stack-unit {0-5} unit {0-0}
ipmc-replication
View the Multicast IPMC replication table from the bShell.
show hardware stack-unit {0-5} unit {0-0}
port-stats [detail]
View the internal statistics for each port-pipe (unit) on per port basis.
show hardware stack-unit {0-5} unit {0-0} register
View the stack-unit internal registers for each port-pipe.
show hardware stack-unit {0-5} unit {0-0}
table-dump {table name}
View the tables from the bShell through the CLI without going into the
bShell.
