Environmental Monitoring
Aggregator 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 22-6 shows the environment status.
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
